Study Notes
Superficial Fascia
- A layer of loose connective tissue located directly below the skin.
- Acts as a medium for vessels, nerves, and glands, including mammary glands and the deep part of sweat glands.
- Softens the body surface and facilitates movement of the skin.
- Contains a reservoir of fat, which helps prevent heat loss.
- Forms retinacula, aponeurosis, and intermuscular septa, which help support and organize muscles and tendons.
- Forms interosseous membranes, which are sheets of connective tissue that separate muscles in the limbs.
Deep Fascia
- A membrane made up of collagen fibers.
- Forms fibrous sheaths around muscles, tendons, and vessels.
- Creates fibrous median raphe and fibrous pulleys, which are structures that help guide and support tendons.
- Can form broadsheets that enclose and separate muscle groups.
