Collagen type 7 is present in the lamina densa, it is responsible for holding the lamina densa to the lamina reticularis. This type 7 (along with the type 3 of the reticularis layer) also interweaves into the underlying connective tissue to anchor.
Thanks very helpful. can you please provide some information about the morphological informations . is it look like a random fibrous mesh or bundles of fibers? How about the size, the thickness for example or the diameter of fibers?
Not sure what you mean by 'belongs to epithelial tissue', nor how that's any different than 'just part of it', but basically neither, the basement membrane is, as far as I know, CREATED BY the epithelial cells, and is a non-cellular layer which connects the epithelium to underlying connective tissue. I'm still somewhat confused about it's component parts, though.
@@dannichols6261 it is non cellular matrix which is secreted by both epithelial cells and connective tissue cells, basement has two parts basal lamina which is secreted by epithelium and second part is reticular lamina secreted by connective tissue layer
The basement membrane is the whole structure, while the basal lamina is just part of the basement membrane. If you compare basement membrane to a whole sandwich, the basal lamina is supposed to be just a slice of bread.
is the basal lamina= lamina lucida???? reticlar lamina=lamina densa???? u said before in the previous video that lamina densa contain basicly type 4 collagen no 3???? i realy get confused????

Thank you so much for this video!. I was having confusion with the basement membrane and this video helped!.
BUT....according to Wiki, the lamina densa is made up of collagen type 4 (IV) not 6 (VI).
I have exam next week and this would be a big problem
but really thanx for the video so helpful
u r right...
Yes, lamina densa is type 4 (IV), not 6 (VI)
Wiki isn’t always trusting sometimes they have false stuff
Yes, 100 percent type IV
Thanks for this video sir... But densa is made up of type 4 collagen.
very well explained, thank you so much
Got confused with collagen 7 until I read the comments and was relieved !!

AMAZING VIDEO
I love your accent, oh dear! Thanks for this vid
This was really great! Thanks!
Great explination thank you 👍
very well explained
Thank youuuuuuuu👍🏻👍🏻
Can you please tell me is all basement membrane structure belongs to epithelial tissue? or just part of it. Thanks!

@@dannichols6261 and it is present between epithelium layer and connective tissue layer
Well done 👍
Good video.
Thank you!
Can I be a part of this programme without having the money for it ?
Great job!
Nice work
collagen type 4 ...not type 7 please
thank u so much !
wich is the difference between the membrane and the lamina?
The basement membrane is the whole structure, while the basal lamina is just part of the basement membrane.
If you compare basement membrane to a whole sandwich, the basal lamina is supposed to be just a slice of bread.
nice work
🙏🏻
is the basal lamina= lamina lucida????
reticlar lamina=lamina densa????
u said before in the previous video that lamina densa contain basicly type 4 collagen no 3????
i realy get confused????
Nice work
