Document Summary
6. 1c subcutaneous layer: deep to the integument is the subcutaneous layer, also known as the hypodermis, or superficial fascia. It is not considered a part of the integument. This layer consists of both areolar connective tissue and adipose connective tissue. In some locations of the body, adipose connective tissue predominates, thus the subcutaneous layer is called subcutaneous fat. The connective tissue fibers of the reticular layer of the dermis are extensively interwoven with those of the subcutaneous layer to stabilize the position of the skin and bind it to the underlying structures. The subcutaneous layer pads and protects the body, acts as an energy reservoir, and provides thermal insulation: drugs often are injected into the subcutaneous layer because its extensive vascular network promotes rapid absorption. Normally, the subcutaneous layer is thicker in women than in men, and its regional distribution also differs between the sexes.
