Membranes- Chapter 3.1

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)

peri%%cardi%%um- 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
