Across
- 2. in hair, the innermost layer of keratinocytes originating from the hair matrix
- 3. active phase of the hair growth cycle
- 4. cell: type of stem cell found in the stratum basale and in the hair matrix that continually undergoes cell division, producing the keratinocytes of the epidermis
- 6. pili: smooth muscle that is activated in response to external stimuli that pull on hair follicles and make the hair “stand up”
- 8. transitional phase marking the end of the anagen phase of the hair growth cycle
- 13. type of structural protein that gives skin, hair, and nails its hard, water-resistant properties
- 17. structure that forms an impermeable junction between cells
- 18. cell: receptor cell in the stratum basale of the epidermis that responds to the sense of touch
- 20. skin condition due to infected sebaceous glands
- 21. type of callus that is named for its shape and the elliptical motion of the abrasive force
- 22. pigment that determines the color of hair and skin
- 24. sore on the skin that develops when regions of the body start necrotizing due to constant pressure and lack of blood supply; also called decubitis ulcers
- 26. cell that produces keratin and is the most predominant type of cell found in the epidermis
- 28. bulb: structure at the base of the hair root that surrounds the dermal papilla
- 29. sweat gland: type of sweat gland that is common throughout the skin surface; it produces a hypotonic sweat for thermoregulation
- 31. fibers: fibers made of the protein elastin that increase the elasticity of the dermis
Down
- 1. cell found in the stratum basale of the epidermis that produces the pigment melanin
- 5. sweat gland: type of sweat gland that is associated with hair follicles in the armpits and genital regions
- 7. follicle: cavity or sac from which hair originates
- 9. genetic disorder that affects the skin, in which there is no melanin production
- 10. gland: type of oil gland found in the dermis all over the body and helps to lubricate and waterproof the skin and hair by secreting sebum
- 11. clear protein-bound lipid found in the stratum lucidum that is derived from keratohyalin and helps to prevent water loss
- 12. type of scar that has layers raised above the skin surface
- 14. collagen-rich skin formed after the process of wound healing that is different from normal skin
- 15. layer of skin between the epidermis and hypodermis, composed mainly of connective tissue and containing blood vessels, hair follicles, sweat glands, and other structures
- 16. type of skin cancer that originates from the melanocytes of the skin
- 19. in hair, the second or middle layer of keratinocytes originating from the hair matrix, as seen in a cross-section of the hair bulb
- 23. outermost tissue layer of the skin
- 25. matrix: layer of basal cells from which a strand of hair grows
- 27. skin condition due to an allergic reaction, which resembles a rash
- 30. thickened area of skin that arises due to constant abrasion
