    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…

    Does Cut Hair Grow Back Thicker, Darker or Faster?

    To understand the answer, it’s worth taking a look at what hair is. Basically, it’s a protein filament, which is a long chain of proteins, that grows from hair follicles. 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…

    The Integumentary System

    It’s Professor Dave, let’s look at the integumentary system. With some basics covered regarding two of the types of tissue in the human body, we are ready to start looking at some of the different systems found in the body, and we are going to start with the outermost system, which is called the integumentary system. This is made up of the skin that covers and protects all your other body parts, as well as its derivatives, like certain glands, as well as hair and nails. Let’s look at the structure and function of these components now. The skin is a remarkable organ, acting as the first line of defense…
