Tissues and Cells
Cards in this deck (40)
- 1Flexure LinesForm where the dermis is closely attached to the underlying facia.
- 2Clevage (tension) LinesRepresents seperations between underlyin collagen fiber bundles in the reticular region of the dermis. They tend to run circularly around the trunck and longtitudially in the limbs.
- 3Reticular LayerAccounts for about 80% of the dermis, is course, dense irregular connective tissue.
- 4Stratum LucidumVisible only in thick skin, is a thin translucent band just above the Stratum Granulosum.
- 5Thick SkinCovers areas subject to abrasion - The palms, fingertips, and soles of the feet.
- 6KeratinizationThe process in which the cells fill with Keratin
- 7Statum Germinativum-Stratum Basale-
Deepest epidermal layer, one row of actively miotic stem cells; some newly formed cells become part of the more superficial layers. See occasional melanocytes and dendritic cells. - 8KaratinocytesKeratinocytes main role is to produce keratin. Most epidermal cells are keratinocytes.
- 9Stratum CorneumMost superficial layer; 20-30 layers of dead cells, essentially flat membranous sacs filled with keratin. Glycolipids in extracellular space.
- 10Stratum GranulosumTypically one to five layers of flattened cells; organelles deteriorating; cytoplasm full of lamellar granules (release lipids) and keratohyaline granules.
- 11Stratum SpinosumSeveral layers of keratinocytes unified by desmosomes, Cells contain thick bundles of intermediate filaments made of pre-keratin.
- 12Stratum BasaleDeepest epidermal layer; one row of actively mitotic stem cells, some newly formed cells become part of the more superficial layers. See occasional melanocytes and dendritic cells.
- 13Superficial FasciaHypodermis subcutaneous tissue, not part of the skin
- 14Third-Degree BurnsA burn that involves the entire thickness of the skin; also called a full-thickness burn. Usually requires skin grafting.
- 15Sudoriferous GlandsEpidermal Gland that produces sweat
- 16Sweat Glands-Sudorifrous Gland-
Epidermal Gland that produces sweat - 17Second Degree BurnsA burn in which the epidermis and the upper region of the dermis are damaged
- 18SebumOily secretion of sebaceous glands
- 19Sebaceous GlandsEpidermal Glands that produce an oily secretion called sebum.
- 20Rule of ninesMethod of computing the extent of burns by dividing the body into a number of areas, each accounting for 9% (or a multiple thereof) of the total body area.
- 21MelaninDark Pigment formed by cells called melanocytes imparts color to skin to hair
- 22Mammary GlandsMilk producing glands of the breast
- 23KeratinFibrous protein found in th epidermis, hair, and nails that makes those structures hard and water resistamt; precursor is keratohyaline.
- 24Merocrine Sweat GlandsGlands that produce secretions intermitently; secretions do not accumulate in the gland.*
- 25Stratum Spinosumseveral layers of keratinocytes unified by desmosomes, cells contain thick bundles of intermediate filaments made of pre-keratin
- 26Integumentary SystemSkin and its derivitives; provides the external protective covering of the body
- 27Hair FolliclesStructure with outer and inner root sheaths extending fro the epidermal surface into the dermis and from which new hair developes.
- 28HemoglobinOxygen - Transporting protein of erythrocytes
- 29HypodermisSubcutaneous tissue just deep to the skin; consistes of adipose plus some areolar connective tissue.
- 30First-degree BurnsA burn in which only the epidermis is damaged
- 31Eccrine Sweat GlandSweat glands abundant on the palms, soles of feet, and the forehead
- 32EpidermisSuperficial layer of the skin; composed of keratinized stratified squamous epithelium
- 33DermisLayer of skin deep to the epidermis composed mostly of dense irregular connective tissue
- 34Dendritic CellsProtective cells that engulf antigens, migrate to lymph nodes, and present the antigen to T cells, causing them to activate and mount an immune response; those in the skin are sometimes called langerhans cells.
- 35CaroteneYellow to orange pigment that accumulates in the stratum corneum epidermal layer and in fatty tissue of the hypodermis
- 36BurnTissue damage inflicted by intense heat, electricity, radiation or certain chemicals all of which denature cell proteins and kills cells in the affected area.
- 37Arrector PiliTiny, Smotth muscles attached to hair follicles; contraction causes the hair to stand upright.
- 38AlopeciaBaldness
- 39Apocrine sweat glandsThe less numerous type of sweat gland; produces a secretion containing water, salts, proteins, and fatty acids.
- 40ABCD RuleAsymmetry: the two sides of the pigmented spot or mole do not match
Border irregularity: The borders of the lesion exhibit indentations
Color: The pigmented spoy contains several colors (blacks, browns, tans, somtimes blues and reds)
Diameter: The spot is larger than 6mm in diameter (the size of a pencil eraser)
