Chapter 3.1:

membranes- surround and help protect the body’s surfaces

Epithelial:

epithelial membranes- provide a lining for the internal and external surfaces of the body

epithelial membrane structure- a sheet of epithelial cells with an underlying layer of connective tissue

Mucous:

mucous membranes- line the body cavities that are open to the outside world, also line hollow organs of the respiratory system, all moist

mucous membranes structure- a layer of epithelium over a layer of loose connective tissue called lamina propria

Serous:

serous membranes- line body cavities that are closed to the outside world

pleura- encloses the lungs (serous)

pericardium- surrounds the heart (serous)

peritoneum- lines the abdominal cavity (serous)

serous membrane structure- outer layer of simple squamous epithelium on a thin layer of loose connective tissue

serous fluid- serves as a lubricant between parietal and visceral membranes to minimize friction

Cutaneous:

cutaneous membrane- another name for skin

structure of cutaneous membrane- keratinizing, stratified squamous epithelium over dense, fibrous connective tissue

Synovial:

synovial membrane- composed solely of connective tissue, no epithelial cells

synovial membrane location- line capsules that surround synovial joints, also line tendon sheaths

synovial fluid- provides cushioning and reduces friction

bursae- small, connective tissue sacs that serve as cushions for tendons and ligaments surrounding the joints
