Document Summary
Body membranes: cover surfaces, line body cavities and form protective (+lubricating) sheets around organs-2 groups: epithelial membranes: include cutaneous, mucous and serous membranes, connective tissue membranes: include synovial membranes. Classification of body membranes: 2 major categories-epithelial and connective classified according to tissue makeup: epithelial membranes (aka covering/lining membranes) Contain epithelial sheet with an underlying layer of connective tissue: cutaneous membranes: your skin. Composed of epithelial over connective tissue membrane called a lamina propria. Wet, moist membranes bathed in secretions or urine (in the urinary tract: serous membranes. Layer of simple squamous epithelium on thin layer of areolar connective tissue. Line body cavities that are closed to the exterior (except dorsal body and joint cavities) Occur in pairs: parietal layer lines wall of ventral cavity: visceral layer: folds of parietal layer covering the outside of organs in that cavity. Layers separated by serous fluid secreted by membranes: allows organs to slide past one without friction.
