    Skin Keratinized.mp4

    – [Voiceover] This slide is keratinized skin. The current magnification is 40X total magnification. Now what we’re looking for are the various layers that are found within the skin. So what I hope you can notice is more towards the top of the slide up here, you have this kind of pinkish red and this almost gray color. This is one portion of the epidermis. The other portion is going to be this purple, this dark and lighter purple. Together, from here all the way down to the bottom of that purple, is considered the epidermis.

    Integumentary System: Functions

    Okay, now we’re gonna discuss the functions of the integumentary system. And most people think of it as fairly straightforward, in terms of protection. Protection is one of the key functions of the integumentary system, however, it certainly is not the only function. And we’ll go into quite a bit more detail in terms of the others, but we’re going to start with protection first, because it is truly one of the most important functions. Now, first and foremost, I want to start our discussion talking about the proteins that are associated with the integumentary system, particularly, with the most superficial layer, the epidermis. Now, in terms of the epidermis,…

    Integumentary System: Layers of Skin & Functions – Dermis

    Okay, let’s continue our discussion of the integumentary system with the deepest layer of the skin. So remember the epidermis is going to be superficial and right underneath it will be the dermis, which is quite a bit more substantial, both in terms of size as well as contents. Okay, so the dermis is situated between the more superficial epidermis and the deeper subcutaneous or hypodermal region. And it’s mentioned before there are lots of stuff in there. So you’ll have hair roots, you’ll have muscles associated with hair, you’ll have sensory receptors, you’ll have glands and very importantly, particularly in terms of the survival of the epidermis, you’re going…

You might remember from anatomy class in school that your skin has two main layers, an epidermis closer to the surface and a dermis underneath it. The epidermis has four or five sub-layers, depending on its location in the body, and the dermis has two sub-layers. Hair follicles are organs housed within the dermis. The role of the follicles is to regulate the growth of hair. So hair begins growing from a root in the bottom of the follicle, which…
