The subcutaneous tissue (from Latin subcutaneous 'beneath the skin'), also called the hypodermis , hypoderm (from Greek 'beneath the skin'), subcutis , or superficial fascia , is the lowermost layer of the integumentary system in vertebrates . The types of cells found in the layer are fibroblasts , adipose cells , and macrophages . The subcutaneous tissue is derived from the mesoderm , but unlike the dermis , it is not derived from the mesoderm's dermatome region. It consists primarily of loose connective tissue and contains larger blood vessels and nerves than those found in the dermis. It is a major site of fat storage in the body.

It is often mechanically strengthened, for example, in pine leaves, forming an extra protective layer or a water storage tissue. Subcutaneous fat is the most widely distributed subcutaneous tissue layer. It is composed of adipocytes, which are grouped together in lobules separated by connective tissue . The number of adipocytes varies among different body areas, while their size varies according to
