INTRODUCTION TO ANATOMY AND PHYSIOLOGY

Subcutaneous Layer (Hypodermis)

The Hypodermis or Subcutaneous tissue is as you will see from the diagram below the “innermost” layer of the skin located under the Dermis.  It consists of connective tissue and fat and houses the larger blood vessels and nerves.  It functions as an insulator and helps to regulate the bodies temperature.   The thickness of this layer varies according to external factors (such as age, gender, and dietary habit) and also within the body thickness varies according to location.

The Hypodermis layer divides the Dermis layer from the subjacent muscles and permits the skin to move without restriction in the majority of the body.

The fat cells (Adipose tissue)– cushion and protect the mass of blood vessels and nerve endings in this region.

Sweat glands– regulate the body temperature and are part of the detoxification system of the body.

Sweat glands – these help to control body temperature (maintaining the correct temperature) and help with detoxification.

Sebaceous glands-secrete oils (sebum), which are mainly found in combination with hair follicles. They occur independently only in the area around the nipples, the eyelids, and the mucous membranes of the lips.
