I just wanna say...THANK YOU. What I love the most about your lectures is the way you speak with such tranquility and enthusiasm at the same time. You are giving me the motivation to study and when I study from your lectures I feel more concentrated because you don't put any pressure. It's like you are talking about something ordinary without making big deal out of it and that is very helpful. I feel less stressed when I hear your voice saying internal elastic lamina. Once again, big thanks!

A few questions: 1. Is the *internal elastic lamina* a part of the *tunica interna* ? 2. And can the *sub-endothelial layer* alternatively be termed the *basement membrane* ? And/or if basement membrane is a correct term, would it be more correctly said to be comprised of *both* the sub-endothelial layer *and* the internal elastic lamina? 3. And is the *external elastic lamina* a part of the tunica *media* , or of the tunica *externa* ? 4. At ~5:59, speaking about *dense irregular connective tissue* , the *closed captions* says, '...it's out as that neural arrangement...', but I suspect that's not what you said. What did you say?

The books seldoms give a clearly distiction between the different types of capillaries, when they mention fenestrated and sinusoids capillaries interchangeably. This is confusing from time to time. (Even my professor at the medical faculty of Oslo says that capillaries in endocrine glands are both sinusoids and fenestrated). It's about time someone clear this up. Thanks a bunch.

Hello , my book says that the Tunica Externa is composed of Areolar CT. Is it possible that in some come vessel there is dense irregular ct, while in other vessels there is areolar ct? Or is it one of those things in biology that has yet to have solid backing so there's not a consensus as to which ct the tunica externa is composed of? ty
