Question | Answer |
---|---|
Apocrine Sweat Gland | Located in the axilla and genital regions; these glands enlarge and begin to function at puberty |
Appendage | The hair, nails, and skin glands |
Areola | Small space; the pigmented ring around the nipple |
Arrector Pili | Smooth muscles of the skin, which are attached to hair follicles; when contraction occur, the hair stands up resulting in “goose flesh” |
Basement Membrane | The connective tissue layer of the serious membrane that holds and supports the epithelial cells |
Blister | Fluid filled skin legion |
Bursa | Small cushion-like sacs found between moving body parts, which make movement easier |
Cutaneous Membrane | Skin; Primary organ of the integumentary system |
Cuticle | Skinfold covering the root of the nail |
Dermal-epidermal Junction | Junction between the thin epidermal layer of the skin and the dermal layer providing support support for the epidermis |
Dermal Papilla | Upper region of the dermis that forms part of the dermal-epidermal junction and forms the ridges and grooves of fingernails |
Dermis | The deeper of the two major layers of the skin, composed of dense fibrous connective tissue interspersed with glands, nerve endings, and blood vessels; called “true skin” |
Eccrine Sweat Gland | Small glands distributed over the total body surface |
Epidermis | False skin; outermost layer of the skin |
Follicle | Specialized structures required for hair growth |
Freckle | Small brown or red macules that are a common genetic variant of normal skin pigmentation |
Hair Follicle | Small tube where hair growth occurs |
Hypodermis | The loose ordinary tissue just underneath the skin and superficial to the muscles |
Integument | Another name for skin |
Integumentary System | Hair, nails, and skin glands as an organ system; the skin |
Keratin | Protein substance found in hair, nails, outer skin cells, and horny tissues |
Lanugo | The extremely fine and soft hair found on a newborn infant |
Lunula | Crescent-shaped white area found under the proximal nail bed |
Meissner's Corpuscle | A sensory receptor located in the skin close to the surface that detects light touch |
Melanin | Brown skin pigment |
Melanocyte | Specialized cells in the pigment layer that produce melanin |
Membrane | Thin sheetlike structure with an important function in the body |
Mucocutaneous junction | The transitional area where the skin and mucous membrane meet |
Mucous Membrane | Epithelial membrane that lines the body surfaces opening directly to the exterior and secrete a thick, slippery material called mucus |
Mucus | Thick, slippery material that is secreted by the mucous membrane and keeps the membrane moist |
Pacinian Corpuscle | A receptor found deep in the dermis that detects pressure on the skin surface |
Papilla | Small, nipple shaped elevations |
Parietal | The walls of an organ or cavity |
Perietal Peritoneum | Serious membrane that lines and is adherent to the wall of the abdominal cavity |
Parietal Pleura | Serous membrane that lines and is adherent to the wall of the thoracic cavity |
Peritoneum | Large, moist, slippery sheet of serious membrane that lines the abdominopelvic cavity |
Perspiration | Transparent, watery liquid released by glands in the skin that eliminates ammonia and uric acid and helps maintain body temperature; also commonly known as sweat |
Pigment Layer | The layer of the epidermis that contains the melanocytes that produce melanin to give skin its color |
Pleura | The serious membrane in the thoracic cavity |
Pore | Pinpoint-size openings on the skin that are outlets of small ducts from the eccrine sweat glands |
Sebaceous Gland | Oil-producing glands found in the skin |
Sebum | Secretion of sebaceous glands |
Serous Membrane | Found only on surfaces with closed cavities; composed of two distinct layers of tissue |
Stratum Corneum | The rough outer layer of the epidermis; cells are filled with keratin |
Stratum Germinativum | The innermost of the tightly packed epithelial cells of the epidermis; cells here are able to reproduce themselves |
Subcutaneous Tissue | Tissue below the layers of the skin; made up of loose connective tissue and fat |
Sudoriferous Gland | Glands that secrete sweat |
Synovial Membrane | Connective tissue membrane lining the spaces between bones and joints that secretes synovial fluid |
Visceral | Pertaining to the viscera or internal organs |
Visceral peritoneum | Serous membrane that covers and is adherent to the abdominal viscera |
Visceral Pleura | Serous membrane that covers and is adherent to the lungs |
