Lying below or under the cutaneous (dermis, leather) tissue. This tissue is usually composed of fat cells and the structures that run through it, i.e., blood vessels, nerves, etc. Fat is a soft, shock-absorbing barrier that acts as a conduit for the nerves and blood vessels. As well, subcutaneous tissue is an energy-storage device. See Fat in the glossary. The sebaceous glands of the hair follicle arise in the subcutaneous layer and are in high concentration on the face and scalp. There are no sebaceous glands on the palms or soles.
