got my sl exam tomorrow, last minute reviewing, praying i get a 4/5, and this vid helped so much. thank you 🙏
This video is incredibly helpful, (as with all your other videos!) Thank you very much for all these topic breakdowns, my whole sports science class watches your videos for revision. They are very understandable and concise. We don't know how we would survive IB without this channel :D
Thank you very much. More will follow over the next few months. Good luck to your class
This is such a great video, thank you for making and sharing! I like the analogy of the muscle contraction, it makes something complicated very accessible!
Glad you enjoyed it!
👍
hi can somone explain what is the actin and myosin

Watch this video carefully. Explains the whole muscular contraction sequence, including the role of actin and myosin (they are just filaments that slide over each other to allow a muscle to contract).
sliding filament theory is so hard, still don’t sure if i know it enough for an exam.
Do a bullet point list of key events. Start backwards if it helps. Starting with the contraction itself. If it is still overwhelming, break it down into stages. So look at the synapse and what makes everything happen there. Then look at the impulse traveling through the muscle. And then look at contraction including role of calcium ions and ATP. Remember sodium ions are responsible for transporting the impulse and when sodium ions arrive at the synapse, and at the sarcomere, they positive charge that area. This opens up calcium ion gates allowing calcium ions in. They are responsible for making a change. So sodium for transport and charge and calcium for change. Calcium ions allow ACl to transmit the impulse across the synapse whereas the calcium ions move the troponin and tropomyosin in the sarcomere allowing actin and myosin to interact (with the presence of ATP). Just write down a bullet point list of 6 things and learn them in a chain of events. Don’t overcomplicate it. If you are struggling, have a bullet point list of 3 events and add to it when you are more confident.
ur so cute
