This video was put on as a test for one of my classes that I don't teach anymore. I have no plans of redoing it or doing any more chapters for those who keep asking. There are 2 or 3 mistakes. Rectus abdominus originates on the pubis and inserts at the costal angle. Orbicularis oris is around the mouth and orbicularis oculi is around the eye. Brachioradialis originates on the distal humerus and inserts on the ulnar tuberosity (really fascia between ulna and radius). I've heard both protagonist and agonist for the opposite of the antagonist. I assume they are both correct.
Great lecture, however at the end some mistakes start creeping in:
40:15 - the Serratus anterior originates on the ribs, and does not insert on the Humerus but on the Scapula; the muscle is used for shoulder protraction/abduction
41:18 - the Trapezius muscle is now generally talked about in three parts, not two: the upper or descending part; the middle or transverse part; and the lower or ascending part. The transverse trapezius among other things takes care of scapula retraction/adduction, pulling them straight towards the spine. An opposite of the Serratus anterior in this
42:04 - the Tricpes brachii does not originate on the Olecranon of the Ulna, but inserts there. It conversely originates on the Humerus and Clavicula. The terms are swapped with each other.
42:36 - he names the muscle Brachialis but points at and talks about the Brachioradialis
43:45 - he says "flexors" but means to say "extensors"
48:10 - the upper part of the picture seems correct, I could find no reference to the Gluteus minimus originating on the Sacrum; I think he is confused with the Piriformis which inserts pretty close to the insertion of the Gluteus minimus, but does originate from the Sacrum. However, the lower part of the muscle seems to be drawn wrong; the muscle inserts on the anterolateral aspect of the greater trochanter of the Femur (so the head of the Femur), instead of much lower on the Femur as shown in the picture where it could not fulfill its function
50:36 - contrary to what he says, that must be the Plantaris muscle
51:13 - "Foot extensors" should indeed be called "Foot dorsiflexors", his correction is a bit unclear
51:53 - instead of "dorsiflexors" he means to say "plantarflexors"
All verified using university grade software 'Elsevier's Complete Anatomy' (it's awesome and has a free trial, check it out) and double checked on wikipedia and google image search
Thanks for the corrections. This was actually an experiment and wasn't really meant to stay on here, but so many people watch it I just left it up. It was my first ever lecture video and then I stopped teaching this class. There are lots of mistakes. Some, however, I learned that way. Not everyone agrees when it comes to science.
@@MarkJolley I really appreciate you kept the lecture on UA-cam, one of the best I could find!
I'm just commenting a time stamp here just to help me in my studies.
9:55 - Neuromuscular Junction
18:02 - Some Gross Anatomy & Muscle Function
26:36 - Nomenclature
34:16 - Muscle Labeling
Thank you so much for so much for creating this video!
Thank you for these time stamps
Peen
my favorite parts are when he says stuff like "I don't know" "whatever" "doesn't really matter"

My professor says "who cares"
omg I'm going to cry. My teacher sucks ass at teaching anatomy. THANK YOU FOR CREATING THIS!!!!
How did it go, did u ace ur A&P?
i learned more in this video than i did the whole semester. thank you!! :)
Lindsay That's sad.
Same here. Only chapter I learned past random memorization.
It's been 11 years since this lecture was uploaded but still very relevant and helpful! Thank you for your help!
On a side note: I wish more professors/instructors would consider uploading their lectures to youtube. Talking about it once and then expecting students to learn what they didn't retain in a textbook is such an outdated way to teach.
This is one of the best lectures I have ever seen. 10 minutes in and 4 full pages of notes. Wow! What I'd do to have a professor like you.
i just wanted to add at 19:26 you said orbicularis oris was around the eyes but its actually around the mouth. orbicularis oculi is around the eyes.
If I said that it was a mistake. You are correct.
yeah i was like hold up!!!!
cougarangel123 34:35 he correctly address the orbicularis oculi when going over the head & neck muscle. I’m sure it was just a genuine mistake.
I have spent months studying anatomy and discovered a great resource at Anatomy Blueprint Pro (google it if you're interested)
cougarangel123 I
I love this video, clear and simple explanation. Thank you and you made it easier and loving. I can't stop laughing as well when you say "...I don't know it doesn't real matter.." re: contraction of rectus abdominis. I just felt good that someone is with us or feels the same about how hard its to even master the naming of this muscles. Best professor you are. I wish you were my professor.
The best one I've seen, learned more here than in A&P

Nomenclature: 26:36
Muscle labeling: 34:16
Super helpful, thanks so much for this!
Thank you so much! I'm going to add these to my personal bookmarks as well.
what a great way to explain the muscular system. This video helped me understand what my professor wasn't able to explain so well. i wish you had all the systems and chapter for the Anatomy & Physiology classes.
I don't think you're boring Thank you for sharing your knowledge, I'm staying to take a test
Thankyou Professor for taking your precious time to explain the lesson. May God bless you and your family ❤❤❤
Thank you for making this available. And thank you for caring about viewers/students understanding muscle tissue & systems. It is evident that you have learned how humans learn. 👏👏
Thank you so much. This is very helpful to a struggling BIO 210 (physiology and anatomy student) in SC.
I am watching this even though I am not going to become a doctor, I am just that bored. Thanks to Coronavirus
TashinTV same
You're not bored just hunting for knowledge, something we don't do enough because of all the distractions we have around us
I just got done watching night shift on Netflix now I just want to be a surgeon lol
You can also use this for drawing, you could probably be an artist
Same here 🤣🤣😂
I watched 2 other lectures by 2 different people and learned certain things in this video that I didn't understand in the last two. those video clips in the middle of the lecture are so helpful. his humor is great lol & he uses some good comparisons so it's easy to remember things. thank you for your lecture ! 😎
What a video man I actually am learning through Anatomical structure but find it difficult to constructively include the study of whatever you are teaching too. Keep it up!
you helped me so much on my lab quiz today, thank you. you explain it better than i've ever had it explained
Thank you for the explanation around 20 minutes about the agonists, antagonists, & synergists muscles and functions. It really helped !! Loved the literature references for protagonist, etc. Ha !
Wish my teachers taught like this
If you is interested in human anatomy the greatest results that I have had was with the Anatomy Blueprint Pro (i found it on google) without a doubt the most incredible info that I have ever tried.
Heéy
@@maggiemaggie8887 Are you not lying?
great video! Im a visual and auditory learner this helped me very much.
Oh absolutely ❤️
thanks for the information, you're helping me get an A+ in my online Anatomy class. :D
Thank you so much. My AP Bio teacher cant even pronounce half of what she is teaching us correctly. Then again i live in MS. So here i am on youtube teaching myself.
Straightforward, not too dry, well done.
I thought that connective tissue from all of the layers merged together at the end of the muscle to form the tendon, not just the fascia. In other words, fibers from the endomysium, perimysium, and epimysium (as well as the fascia) all merge together to form the tendon. The reason for this is to distribute the force from ALL of the contracting fibers onto the tendon to provide enough force for movement.... Just making sure my understanding is correct.
you are absolutely correct.
+TeachMeAandP I have spent months studying human anatomy and found a great resource at Anatomy Blueprint Pro (google it if you are interested)
Great lecture. Very helpful. I have an exam on this stuff tomorrow night. Small correction: The sartorius is the "Tailors" muscle because they will measure you from where it inserts to where it originates when they measure you or "fit" you properly for a pair of trousers. I'm 95% sure of this :)
Simple!!!!
Apt!!!!
Thank you too much. I struggled with this particular topic in the semester.
Very helpful video. Has been added and saved to my you tube account! Thanks so much!
Nice name lol
very nice video. helped me study for my exam!!
Hey
Ty for this video!! I'm taking an condensed summer anatomy class and really struggling with the muscles, so this vid was super informative!
Nice!
I'm revisiting anatomy to finally learn how to draw the human body, and this was very helpful
37:50 The abs actually inserts there at the ribs and xiphoid process, and originates at the crest of pubic. So the other way around
Also 40:35 The serratus ant. doesnt attach to the humerus in any way
Originates in the ribs
Insert in scapula
Triceps also the other way around
Regardless this is awesome for a UA-cam video mate
The triceps brachii originate on the scapula and humerus and insert on the oleccranon process of the ulna.
I got some answers to unanswered things in the book for my course from this video...just in time for a test - thanks!
this guy saved me with last min work
Exactly what I was looking for. Much respect and thanks for the excellent explanation.
The amount of times he says, "I don't know" resonates with me
🤷🏼♂️
Thanks for this video. Very helpful for studying before taking the MBLEX.
When you said abducted by aliens i had to like
Thank you I had a breakthrough with your lecture.
OMG thank you so much , this really helped me review for my HESI A2 exam.
omg same. i'm taking the HESI next week, i hope i pass!
So the hamstring is in the thighs and its lower than the glutes? (Im watching this for fun, not doing a test lol)
Yes. Posterior thigh.
You know
stevejg1001
i am watchin in terms of excercise 😁😉
And the hamstring needs extra stretching
Breaking bonds reqiuires energy, forming bonds releases energy at least that;s what i know from chemestry courses
Very helpful for last minute exam review! You covered A&P of muscle in details! Thank you 😊
I really enjoyed this lecture... I MIGHT have an answer as to way the 'anatomists' sometimes use 'major' instead of 'maximus' (or 'minor' instead of 'minimus'). 'Major' technically means '(the) biggER (one)' when comparing only 2 things. 'Maximus' translates as 'the biggEST' but only when talking about MORE than 2 things. ;)
This is super informative! We love learning new stuff and try to make our own fun learning videos too.
Agonist - muscle that accomplishes a certain movement while Antagonist - muscle acting in opposition to an agonist
Anyone else love listening to this guy as much as i do ?
Mark Jolley, a big giant, huge thank u
What a great teacher wow !!
muscle anatomy can be a lot to take in ... thanks for simplifying things
The man just has intelligence pouring out of him 😄👏🏻
better than my teacher
Lecture is really helpful. =) Only one that confused me was the brachialis. It originates on the humerus and inserts on the ulna (not radius) from what I've been reading.
If I said that it originates on the ulna then I made a mistake. It originates on the humerus and inserts on the fascia of the ulna (and radius for that matter).
Or if I said it inserts on the humerus that is also wrong. It originates on it.
Thnq soo much for this video.. Now I could memorize these names of muscles
I am very grateful to you for this lecture, very concise and straight to the point, I enjoyed it very very much!
Just loved this video! Thank you...was complete and easy to understand.
Thanks for the video. Will watch it several times. Great teacher.
awesome video... though when i heard this part 27:08 i was really hoping you would go with the pun... and you did not disappoint lol
That`s a great lesson! Thank you so much for work you did to explain all the muscle groups.
Thank you for sharing this information. It's helping me learn the muscles and each action.
triceps brachii insert on the ulna, not originate
I learned a lot of terminology!
Thank you so much! The outline in the Description doesn't work anymore, would you renew it please?
We all appreciate this vid, thanks for sharing it here too 🙏🏼
I don't think I have it anymore unfortunately
@@MarkJolley Got it, no problem. Thanks for a quick response 😄😊
This is so easy to understand. Thankyou so much.
Thank you for doing this lecture! Helped me big time!
Btw this video is absolutely awesome!!!
Great video. Helped a lot. Thank you!
Great video, but a quick question: the relationship of the muscles ( e.g., the triceps brachii and the biceps brachii) all depend on the motion/ action that is being done?
Hey Mark ,I would like to ask you a question but first I would like to tell you ,Thank you for making this video, as it is an amazing video!!! and you have a great talent to make complicated things very easy, hopefully you will make more of those video.
I have a question in minute 5:22 you are talking about the Sarcoplasm and then you say its -filled with myofibrils
*STORE GLYCOGEN AND OXYGEN
what I don't understand is ,who stores the glycogen and oxygen is it the Sarcoplasm or the myofibrils?
Thank you
Very nice class and very clear thanks for sharing
My sacrifices to become a good artist
Thank you it was very helpful
Thanks very much for this video. I think I'll watch it a few times.
I saw a lot of Anatomy Lesson on UA-cam. You are very Good.
THANK YOU SOOOOO MUCHHHHHH ~~~~~~~
thank you for this amazing video lecture!!!
Great teacher!
Thank you so much professor
great video! very helpful
The human body is amazing
Thnqu so much sir
If you speed it up to 1.25 he will seem much more excited giving the lecture lol
andriass toros ha ha. All you millennials need to be taught like it's preschool.
You're a grown ass man and you haven't yet learned that generalizing is wrong. Pretty sad. You're probably just butthurt because you're starting to get gray hair and you wish you'd be young again, it's okay. I feel bad for you.
andriass toros yes, that's it.
Excellent!! So much incredible work you have put. Thanks
Really good explanation. But there are some errors with the origin and insertion of some of the muscles. I'll still use the video, but I will go and check each single muscle with some pictures from google. Just write: "name of the muscle orgin insertion action".
When the brain recruits more muscle cells to contract. How does it do that?.... just activate more motor neurons?... what’s the process called of recruiting more muscle fibers to contract?
very informative
Thank you! It is a wonderful rendering! Understood completely...Please make more videos...
God bless you my friend
one question, you mentioned that the Brachialis originates on the Humerus, and inserts on Radius. I thought it inserts on the Ulna..? let me know, I could be wrong. thanks
John Kim you are correct it attaches at the Coronoid and tuberosity of the Ulna
oh man this helped me so much, i was struggling
Thank you for the knowledge my good sir
didnt think id find a member of the litty committee here
This very usefull for me,
You explained well all the important muscles..
thankyou very much...
43:36 medial epicondylitis is called "golfers elbow" not "tennis elbow"
That's true. Tennis elbow is lateral epicondylitis. I made a few mistakes.
I thought Triceps bracii originates from scapula and posterior shaft of humerus not olecranon process of ulna.
Would you put more Anatomy Lecture?
34:15
He sounds like he doesn't care at all, and like he's bored, even sighing throughout the video, but its very informative and easy to understand so whatever
Michael Sharf 😞
Hey it was an amazing lecture! Kudos!
great video and notes thanks!
