- 17. type of skin cancer that originates from the melanocytes of the skin
- 18. partial-thickness burn that injures the epidermis and a portion of the dermis
- 21. collagen rich skin formed after the process of wound healing that is different from normal skin
- 22. skin condition due to an allergic reaction, which resembles a rash
- 23. fibers made of the protein elastin that increase the elasticity of the dermis
- 26. 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
- 27. burn in which full thickness of the skin and underlying muscle and bone is damaged
- 28. basal part of the nail body that consists of a crescent-shaped layer of thick epithelium
- 29. connective tissue connecting the integument to the underlying bone and muscle
- 31. keratinous filament growing out of the epidermis
- 32. type of structural protein that gives skin, hair, and nails its hard, water-resistant properties
- 34. superficial burn that injures only the epidermis
- 36. cavity or sac from which hair originates
- 37. in hair, the innermost layer of keratinocytes originating from the hair matrix
- 39. mark formed on the skin due to a sudden growth spurt and expansion of the dermis beyond its elastic limits
- 42. outermost tissue layer of the skin
- 43. compound that aids absorption of calcium and phosphates in the intestine to improve bone health
- 45. receptor in the skin that responds to light touch
- 47. layer of basal cells from which a strand of hair grows
- 48. receptor cell in the stratum basale of the epidermis that responds to the sense of touch
- 49. skin condition due to infected sebaceous glands
- 50. type of scar that has layers raised above the skin surface
Down
- 1. corpuscle receptor in the skin that responds to vibration
- 2. skin condition in which melanocytes in certain areas lose the ability to produce melanin, possibly due an autoimmune reaction that leads to loss of color in patches
- 3. thickened layer of stratum corneum that lies below the free edge of the nail
- 6. layer of the epidermis superficial to the stratum spinosum
- 7. layer of the epidermis between the stratum granulosum and stratum corneum, found only in thick skin covering the palms, soles of the feet, and digits
- 9. layer of the epidermis superficial to the stratum basale
- 11. deepest layer of the epidermis, made of epidermal stem cells
- 14. 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
- 15. layer of epidermis upon which the nail body forms
- 18. most superficial layer of the epidermis
- 19. smooth muscle that pulls on hair follicles and make the hair “stand up”
- 20. intercellular vesicle that transfers melanin from melanocytes into keratinocytes of the epidermis
- 24. oily substance that is composed of a mixture of lipids that lubricates the skin and hair
- 25. cell that produces keratin and is the most predominant type of cell found in the epidermis
- 30. type of sweat gland that is common throughout the skin surface; it produces a hypotonic sweat for thermoregulation
- 33. disease in children caused by vitamin D deficiency, which leads to the weakening of bones
- 35. nail fold that meets the proximal end of the nail body, also called the cuticle
- 38. layer of skin between the epidermis and hypodermis, composed mainly of connective tissue and containing blood vessels, hair follicles, sweat glands, and other structures
- 40. type of sweat gland that is associated with hair follicles in the armpits and genital regions
- 41. burn that penetrates and destroys the full thickness of the skin (epidermis and dermis)
- 44. extension of the papillary layer of the dermis that increases surface contact between the epidermis and dermis
- 46. thickened area of skin that arises due to constant abrasion
- 48. pigment that determines the color of hair and skin
