The layers of the limbs consist of skin, fascia (superficial, and deep), muscles, and bones.
Fasciae
The fasciae are found deep into the skin. They are a sheet of connective tissue that support, limit, protect, and interconnect different organs and structures. They allow movement and gliding over of structures, vessels and nerves.
There are two types of fascia:
- Superficial or subcutaneous fascia
- Deep fascia
Superficial fascia
The subcutaneous fascia is attached to the dermis of the skin.
- Contains a large amount of fat.
- It is formed by loose connective tissue.
- Its tissue is thick and varies from one anatomical area to another, and from person to person.
- Its functions are to allow the movement of the skin over the rest of the body, conduct the neurovasculature, and serve as a reserve of energy.
Deep fascia
The deep fascia encloses organized and dense connective tissue.
- An external layer of this fascia is inserted deep onto the superficial fascia to form a thin fibrous lamina that covers most of the deeper area of the body.
- An internal layer of this fascia conforms to the intermuscular septa, a structure that organizes
