Document Summary

Lecture 4 body cavities & skin: body cavities, thoracic/pleural, abdominal/peritoneal, serous membranes. Continuous layer of cells that produces a watery fluid. Lubricant between surfaces in the cavity: visceral, membranes line the organs within the cavity, parietal, membranes line the sides/boundaries of the cavity. Pleura around lungs and heart: skin (integument, tattoos, hair, gland and udder. Thoracic cavity: parietal pleura, pleura cavity, visceral pleura. Peritoneal cavity: connecting peritoneum, double fold of peritoneum suspending organ, contains blood vessels and nerves. Thoracic cavity: contains heart, aorta, trachea, esophagus and thymus, bounded by, ribs, vertebrae, sternum, diaphragm, mediastinal pleura potential space formed by parietal pleura. Integument (skin: function in protection, sensory detection, secretion, fat storage, thermoregulation, communication. Includes: hair, footpads, claws, nail, hooves, baleen, horns, osteoderms. Tattoo process: epidermal-dermal junction, 24 hours post tattoo, tattoo ink in epidermal cells, inflammatory cells and intercellular spaces, 1 month post tattoo, some ink in basal cells of epidermis, most ink containing cells in dermis.
