aluskudede

Aluskudede, or subcutaneous tissue, is the layer of connective tissue located beneath the dermis of the skin. In humans it is often referred to as the hypodermis. This layer lies between the dermis and the underlying fascia and muscles, and its thickness varies by body region, sex, age, and body composition.

The subcutaneous tissue comprises adipose tissue (fat cells) embedded in loose connective tissue, along with small blood vessels, nerves, and lymphatic vessels. Adipose tissue stores energy in the form of fat, provides insulation to help regulate body temperature, and acts as a cushion to protect underlying structures. The loose connective tissue component allows flexibility and serves as a conduit for nerves and vessels that supply the skin.

Function and clinical relevance: The subcutaneous layer plays a key role in energy storage, insulation, and mechanical protection. It also serves as a site where medications can be administered (subcutaneous injections) and as a target for cosmetic procedures such as liposuction. Variations in thickness and fat distribution are influenced by genetics, hormones, nutrition, and aging, and patterns differ across body regions and between sexes.

Conditions affecting aluskudede may include inflammation of the fat tissue (panniculitis), infection (cellulitis), edema, lipomas, or changes due to obesity or lymphedema. Understanding the subcutaneous layer is important in dermatology, surgery, and various medical fields for procedures, diagnostics, and treatment planning.
