| 8460851412 | Classification of body membranes | Epithelial membranes Connective membranes | 0 | |
| 8460855530 | Epithelial Membranes | Composed of epithelial tissues and an underlying layer of connective tissue | 1 | |
| 8460860147 | Connective membranes | Composed largely of various types of connective tissue | 2 | |
| 8460860148 | Membrane | thin, sheetlike structure that may have many important functions in the body. | 3 | |
| 8460864634 | Function of membrane | cover and protect the body surface; line body cavities; cover inner surfaces of hollow organs; anchor organs to each other; secrete lubricating fluids that reduce friction | 4 | |
| 8460871652 | 3 types of epithelial tissue types | Cutaneous Serous Membrane Mucous | 5 | |
| 8460871653 | Cutaneous | The skin Largest and most visible organ Accounts for approximately 16% of body weight | 6 | |
| 8460876710 | Serous Membrane | Two layers: simple squamous epithelium lies on basement membrane Name is determined by its location Parietal: Lines walls of body cavities Visceral: Covers organs found in body cavities Pleura: Thoracic cavity Peritoneum: Abdominal cavity | 7 | |
| 8460884846 | Mucus | Line body surfaces that open directly to the exterior Lines the respiratory, digestive, urinary, and reproductive tracts Mucous membrane varies depending on its location and function Esophagus - tough Stomach - digestion Intestinal tract - absorption Produce mucus, a thick secretion that keeps the membranes soft and moist Do not contain epithelial components, rather connective tissue membranes | 8 | |
| 8460876711 | Pleurisy | inflammation of the serous membranes that line the chest cavity and cover the lungs | 9 | |
| 8460881140 | Peritonitis | inflammation of the serous membranes that line the walls of the abdominal cavity and cover the abdominal organs | 10 | |
| 8460888306 | Synovial membranes | Synovial membranes line the spaces between bones and joints that move Produce a lubricant called synovial fluid which helps reduce friction between surfaces of bones in movable joints Synovial membranes also line the small, cushion like sacs called bursae found between many moving body parts | 11 | |
| 8460888307 | The skin | The primary organ of the integumentary system | 12 | |
| 8460890622 | Epidermis | Outermost and thinnest primary layer of skin Composed of several layers of stratified squamous epithelium | 13 | |
| 8460894212 | Dermis | deeper layer made of connective tissue; thicker than epidermis Composed largely of connective tissue | 14 | |
| 8460900808 | Stratum Germinativum | innermost layer of cells that continually reproduce (undergo mitosis) and the new cells move up toward the surface | 15 | |
| 8460900809 | Keratin | protein that is tough, waterproof material that provides cells in the outer layer of the skin with a protective quality; also protects the body from excessive fluid loss | 16 | |
| 8460903637 | Stratum Corneum | Outermost layer of keratin-filled cells | 17 | |
| 8460903638 | Blisters | Caused by breakdown of union between cells or primary layers of skin | 18 | |
| 8460909346 | Pigment-containing Layer | Epidermal layer that contains pigment cells called melanocytes, which produce the brown pigment melanin | 19 | |
| 8460914272 | Dermal-epidermal junction | Specialized area between two primary skin layers | 20 | |
| 8460914273 | Papillary Layer | Upper region of dermis characterized by parallel rows of tiny bumps called dermal papillae | 21 | |
| 8460918242 | Reticular layer | Deeper areas of dermis are filled with a network of tough collagenous and stretchable elastic fibers | 22 | |
| 8460918243 | Hair | Hair growth requires an epidermal tubelike structure called a hair follicle Hair growth begins from a small, cap-shaped cluster of cells called the hair papillae, which is located at the base of the follicle Hair root lies hidden in the follicle The visible part of the hair is called the shaft | 23 | |
| 8460921641 | Arrector Pili | A tiny muscle attached to hair | 24 | |
| 8460928093 | Receptors | Specialized nerve endings that make it possible for skin to act as a sense organ Relays messages to the brain of touch, pain, temperature, and pressure | 25 | |
| 8460932202 | Meissner corpuscle | Light touch | 26 | |
| 8460932203 | Pacini Corpuscle | Pressure | 27 | |
| 8460937564 | Free nerve endings | Pain | 28 | |
| 8460940255 | Krause's end bulbs | Vibration | 29 | |
| 8460945691 | Nails | Produced by epidermal cells over terminal ends of fingers and toes Visible part is called nail body Root lies in a groove and is hidden by the cuticle (fold of skin) Crescent-shaped white area nearest root is called lunula Nail bed is a layer of epithelium under the nail Nail bed may change color with change in blood flow | 30 | |
| 8460949702 | Skin glands - 2 varieties | Eccrine Apocrine | 31 | |
| 8460949703 | Eccrine | Most numerous, important, and widespread of the sweat glands Produce a transparent, watery liquid called perspiration (sweat) Flows out through pores on skin surface Functions: eliminate waste and assist in body heat regulation Distributed over the total body surface Skin glands Sweat (sudoriferous) glands | 32 | |
| 8460954333 | Apocrine | Found primarily in armpit (axilla) and around genitals Larger than eccrine glands Secrete a thicker secretion quite different from eccrine perspiration Odor is caused by skin bacteria and not by secretion itself. | 33 | |
| 8460954334 | Sebaceous Glands | Secrete oil, or sebum, that lubricates the hair and skin | 34 | |
| 8460960339 | Sebum | "nature's skin cream" because it prevents drying and cracking of the skin Level of secretion increases during adolescence Amount of secretion is regulated by sex hormones In sebaceous gland, ducts may darken to form a blackhead | 35 | |
| 8460962503 | Important functions for survival | Protection Temperature regulation Sense organ activity | 36 | |
| 8460974485 | Protection (Keratin and Melanin) | First line of defense against Infection by microbes Ultraviolet rays from the sun Harmful chemicals Cuts and tears Excessive fluid loss Temperature regulation | 37 | |
| 8462870474 | Skin is | an enormous sense organ | 38 | |
| 8460975765 | Determining extent of a burn injury | rule of nines | 39 | |
| 8460978249 | First degree burns | Only the surface layers of epidermis are involved | 40 | |
| 8460984839 | Second degree burns | Involve the deep epidermal layers and always causes injury to the upper layers of the dermis Scarring is common | 41 | |
| 8460984840 | Third degree | Characterized by complete destruction of the epidermis and dermis May involve underlying muscle tissue and bone | 42 | |
| 8460985077 | Lesion | insensitive to pain because of destruction of nerve endings immediately after injury - intense pain is soon experienced | 43 |
