Document Summary

Simplest organs only 2 tissue types: consist of epithelium (avascular) attached to ct (with a basement membrane between them, membrane types, mucous membranes (mucosa) Line cavities which open directly to the body exterior. Also called the mucosa of the e. g. digestive, respiratory, urinary, reproductive systems (fig 4. 11) Line closed cavities that do not open to the exterior i. e. abdominal and: allows organs to slide past one another no friction. Also called serosa in the (especially the peritoneal cavity) Double membranes - each composed of epithelial layers (often simple squamous) next to serous cavity, & cts (always areolar): parietal layer against cavity wall, visceral layer against organ. Named for location: pleura lung, peritoneum abdominal organs, pericardium heart. Peri- means surrounding (e. g. pericardium means surrounding the heart: synovial membranes. Areolar ct, no epithelium (only one tissue type!) (tissue level of organization) Skin: epithelium = stratified squamous (named the epidermis, ct = areolar and dense irregular (named the dermis)
