Key Terms
1. Skin- the thin layer of tissue forming the natural outer covering of the body of a person or animal.
2. Epidermis- the thin layer of tissue forming the natural outer covering of the body of a person or animal.
3. Stratum basal- stratum germinativum: the innermost layer of the epidermis
4. Stratum spinosum- a layer of the epidermis found between the stratum granulosum and stratum basale
5. Stratum Granulson- the layer of epidermis just under the stratum corneum or (on the palms and soles) just under the stratum lucidum; contains cells (with visible granules) that die and move to the surface
6. Stratum Corneum- the horny outer layer of the skin
7. Dermis- the skin
8. Papillary Layer- the superficial layer of the dermis raised into papillae that fit into corresponding depressions on the inner surface of the epidermis
9. Reticular Layer- the deeper layer of the dermis formed of interlacing fasciculi of white fibrous tissue
10. Elastin- a protein that is similar to collagen and is the chief constituent of elastic fibers
11. Collagen- an insoluble fibrous protein of vertebrates that is the chief constituent of the fibrils of connective tissue (as in skin and tendons) and of the organic substance of bones and yields gelatin and glue on prolonged heating with water
12. Lunula- a crescent-shaped body part
13. Cuticle- an outer covering layer as the outermost layer of integument composed of epidermis
14. Pili- a hairlike appendage found on the surface of many bacteria.
15. Shaft- The midsection of a long bone
16. Hair follicle- a small cavity in the epidermis and corium of the skin, from which a hair develops.
17. Root of the hair- The root of the hair ends in an enlargement, the hair bulb, which is whiter in color and softer in texture than the shaft, and is lodged in a follicular involution of the epidermis called the hair follicle.
18. Hair bulb- The root of the hair ends in an enlargement, the
