Subcutaneous means "beneath the skin." It refers to the connective tissues and adipose tissues which are in between the skin and above the muscles. There are some other terms that mean the same thing. They are hypodermis and superficial fascia.
What Does Subcutaneous Mean?
Subcutis or subcutaneous are the layers of tissues that are directly positioned under the cutis. The subcutis is mainly composed of the adipose tissue; the physiological function of the subcutis includes the storage and insulation of nutrients. Directly below the subcutis comes a layer of muscle which is covered in a fascia, or a layer of bone that is covered in periosteum.
The blood vessels that are supplied to the skin, which helps in the regulation of body temperature, run through the subcutaneous layer. These layers also contain nerves and nerve endings.
