Document Summary

Outline: covering and lining membranes, cutaneous membrane skin. Epidermis (epithelium) and dermis (connective tissue: mucous membrane (mucosa) lines organs and cavities that open to outside of body epithelial cells secrete mucous coating, serous membranes (serosae) surrounds outsides of organs and lines body cavities. Layers: parietal layer lines body cavity, visceral layer surrounds organs. Body cavities: peritoneum abdominopelvic cavity (stomach area, pericardium pericardial cavity surrounding heart, pleura pleural cavity surrounds lungs (chest area) Integument: functions, waterproof sebum (oil) and glycolipids create barrier, excretion of liquids and salts, sensory receptors for touch, temperature and pain, body temp regulation capillary network, evaporation, hair, protection stops bacteria, protects from dehydration, absorbs and protects. Loose areolar ct (papillary dermis) and below dense irregular ct (reticular dermis: hypodermis (hypo=below) Some dendritic langerhans cells: stratum granulosum. Hypodermis adipose ct stores fat and insulates body anchors the skin to the underlying structures.
