This is the second layer of the skin under the epidermis, it cushions the body from stress and strain, this layer contains nerve endings, sebaceous glands, sweat glands, hair follicles and blood and lymphatic vessels.
The nerve endings in our dermis tell us how things feel when we touch them; they work with our brain and nervous system so that the brain gets the message about what we are touching. The dermis is also full of tiny blood vessels that keep the skin cells healthy by bringing them oxygen and nutrients they need and by taking away waste. The sebaceous glands secrete sebum which is an oily matter that keeps the skin lubricated and water proof, these glands are present throughout the skin except the hands and feet; they are in greatest abundance on the face and scalp. The sweat glands help in the regulation of body temperature by releasing sweat through pores on the skin. The hair follicle grows hair and attached to it is the sebaceous gland; about 50-100 hairs are shed daily from a normal scalp.
The Hypodermis (subcutaneous tissue):
This layer lies below the dermis and attach the skin to underlying bone and muscle as well as supplying it with blood vessels and nerves. It consists of loose connective tissue and elastin (a protein which play a role in the elasticity of skin). The hypodermis contains 50% of body fat. Fat serves as padding and insulation for the body.
