Study Notes
Summary Title: Types of Membranes and Fasciae in the Body
Connective Tissue Membrane: Synovial Membranes
- Synovial membranes are all connective tissue without an epithelial layer.
- They provide a smooth surface and lubricating fluid.
- They are located in the fibrous capsules surrounding joints and in bursae and tendon sheaths that cushion the joints.
- Bursae are closed serous sacs lined by a serous membrane.
Serous Membranes: Serosa
- Serous membranes are composed of two layers: visceral and parietal.
- The pleural membrane surrounds the lungs and contains pleural fluid in the pleural space.
- The pericardial membrane consists of the outer fibrous pericardium and the inner serous pericardium, which contains pericardial fluid in the pericardial space.
- The peritoneal membrane covers the abdominal viscera and lines the abdominal wall. It contains peritoneal fluid in the peritoneal space.
Skin
- The skin is an organ that comprises all four tissue types: epithelial, connective, muscular, and nervous.
- It accounts for nearly 15% of the weight of an average human and has a surface area of 1.8 m2.
- The skin has a superficial epithelial layer (epidermis) with five layers and a deep connective tissue layer (dermis).
- The hypodermis, or subcutaneous tissue, lies deep to the dermis and is composed of adipose and loose areolar connective tissues.
- The skin has appendages, including hair, nails, sweat glands, and sebaceous glands. They are absent in the palm and sole but abundant in the scalp, face, ears, and nostrils.
Fasciae
- Fasciae are bands or sheets of connective tissue beneath the skin.
- There are two types of fasciae: superficial and deep.
- Superficial fascia, or hypodermis, is a loose mixture of adipose and loose areolar connective tissues that unite the skin to underlying structures.
- The deep fascia is more dense than the superficial fascia and interpenetrates and surrounds the muscles, bones, nerves, and blood vessels of the body.
- There are modifications of deep fascia, including intermuscular septa and interosseous membranes, retinacula, palmar and plantar aponeuroses, formation of sheaths around big blood vessels, ligaments, fibrous flexor sheath, and fibrous capsule.
