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

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.

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

@@dannichols6261 and it is present between epithelium layer and 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.
