Anatomy Vocab. 1
Skin, hair, membranes
| Question | Answer |
|---|---|
| Plain Whorl | 2 deltas; at least one ridge making complete circuit (spiral, oval, circular, variant of circle) |
| Plain Arch | ridges enter one side of impression, flow out other side with rise/wave in center |
| Basal cell carcinoma | least malignant & most common skin cancer |
| mucous membrane (mucosa) | forms the linings of body cavities open to exterior (digestive, respiratory, urinary, reproductive) |
| tented arch | possesses either angle, upthrust, or 2/3 basic characteristics of loop |
| articular cartilage | covers articular surfaces of bones |
| articular capsule | joint capsule; envelope surrounding synovial joint |
| fibrous capsule | capsule of fibrous cells/tissues; external layer of articular capsule |
| accidental whorl | combination of 2 different types of patterns |
| double loop whorl | 2 separate loop formations |
| radial loop | flows in direction of radius bone |
| ulnar loop | flows in direction of ulna bone toward pinky finger |
| central pocket loop | one or more free recurving ridges & 2 points of delta |
| coronal | frontal plane that passes through long axis of body |
| spinous | slender and pointed like a spine |
| imbricate | overlapping of successive layers of tissue in surgical closure of a wound |
| eponychium | thickened layer of epidermal tissue over fingernail/toenail; CUTICLE |
| hair--intermittent | follicle dystrophy; follicle leading to fragility |
| hair--absent | brittle slowing growth |
| squamous cell carcinoma | arises from cells of stratum spinosum; scaly, reddened papule gradually forms shallow ulcer with firm raised border (skin cancer) |
| melanoma | caner of melanocytes (5%; often deadly) |
| cuticle | thick proximal nail fold; borders nail overlapped by skin folds |
| carbuncles | composite boils typically caused by bacterial infection; inflammation of hair follicles & sebaceous glands |
| impetigo | pink, water-filled, raised lesions; develop yellow crust & eventually rupture |
| third degree burn | destroy entire thickness of skin--blanched/blackened |
| second degree burn | epidermis & upper dermis--red, painful, blisters appear |
| first degree burn | epidermis is damaged--red & swollen (2-3 days healing) |
| psoriasis | chronic condition; reddened epidermal lesions covered with dry, silvery scales |
| hair root | part of hair enclosed in follicle |
| papillary layer | upper dermal region--uneven with fingerlike projections from superior surface |
| serous membrane | lines cavity w/o opening to outside of body (except joint cavities); serosa |
| parietal peritoneum | lines abdominal wall |
| visceral peritoneum | lines abdominal viscera |
| cutaneous membrane | skin; epidermal and dermal layers |
| keratinization | becoming hard and tough |
| eccrine glands | numerous & all over body; produce sweat |
| stratum lucidum | latter epidermal layer--skin is hairless & extra thick (palms, soles of feet) |
| stratum basale | deepest cell layer of epidermis; closest to dermis |
| stratum corneum | outermost layer--20 to 30 cell layers thick; 3/4 of epidermal thickness |
| hypodermis | deep to dermis--not part of skin but anchors skin to organs |
| hair follicle | compound structures; cavity where hair grows |
| pleura | serous membrane covering lungs & lining thoracic cavity |
| peritoneum | serous membrane lining interior abdominal cavity & covering surfaces of abdominal organs |
| keratin | tough, insoluble protein in tissues--hair, nails, epidermis |
| hair--continuous | no disruptions along shaft |
| hair--fragmented | portion of visible areas of medulla is less than areas when medulla isn't visible |
| hair shaft | projecting from surface of scalp/skin |
| reticular layer | deepest skin layer--blood vessels, swear, oil glands, deep pressure receptors |
| medulla | central portion of certain organs |
| melanocytes | cell that produces melanin |
| sebaceous glands | empties sebum secretion into hair follicles |
| apocrine glands | less numerous sweat gland--produces secretion containing salts, water, proteins |
| melanin | dark pigment synthesized by melanocytes--gives skin color |
| arrector pili | tiny, smooth muscles attached to hair follicles, cause hair to stand upright |
| dermis | deep layer of skin--dense irregular connective tissue |
| epidermis | outer layer of skin; epithelium |
| synovial membrane | lines capsule of synovial joint |
| pericardium | membranous sac enveloping the heart |
