22
Q

the fourth layer of the epidermis when all five layers are present. Also known as the prickle cell layer - polyhedral cells with cytoplasmic processes sometimes called “spines” that extend outward and contact neighboring cells by desmosomes.

A

stratum spinosum

23
Q

The third layer of the epidermis when all five layers are present. - Also known as the granular layer. A thin layer of cells in the epidermis lying above the stratum spinosum and below the stratum corneum

A

stratum granulosum

24
Q

The second layer of the epidermis when all five layers are present. A thin, somewhat translucent layer of cells lying superficial to the stratum granulosum and deep to the stratum corneum, especially in thickened parts of the epidermis (palms of the hands, soles of the feet).

A

stratum lucidum

25
Q

Outer, horny layer of the epidermis

A

stratum corneum

26
Q

the thick layer of the skin beneath the epidermis

A

dermis

27
Q

smooth muscle in the skin associated with a hair follicle

A

arrector pili muscle

28
Q

specialized structure associated with the peripheral end of a sensory neuron specific to detecting a particular sensation and triggering a nerve impulse in response, which is transmitted to the central nervous system

A

sensory receptors/ nerve fibers

29
Q

gland that secretes its products into a duct or onto a body surface

A

exocrine glands

30
Q

skin gland that secretes sebum

A

sebaceous glands

31
Q

oily secretion of the sebaceous glands

A

sebum

32
Q

exocrine gland in the skin that secretes a mixture of water, salt, urea, and other bodily wastes.

A

sweat/sudoriferous glands

33
Q

type of gland whose secretions contain parts of secretory cells

A

loose connective tissue layer that is mostly fat and is beneath the skin; hypodermis

A

subcutaneous layer

37
Q

glands that produce cerumen

A

38
Q

wax-like substance produced by cells that line the external ear canal

A

Q

cancer that forms in epithelial tissue

A

carcinoma

45
Q

cancer that forms in melanocytes

A

melanoma

46
Q

damage to the skin from ultraviolet radiation that may cause mutations in skin cells.

A

sunburn

47
Q

a form of non-ionizing radiation that is emitted from the sun and artificial sources. Its wavelength is shorter than the visible light spectrum which causes it to be invisible.

A

ultraviolet radiation

48
Q

superficial burn (previously first-degree burn) - only affects the epidermis

A
49
Q

nvolves the epidermis and part of the dermis; the burn site may appear red, blistered, and may be swollen or painful

A

partial thickness burn (previously second-degree burn)

50
Q

extends through and destroy all layers of the dermis and often injures the underlying subcutaneous tissue

A

full thickness burn (previously third-degree burn)

51
Q

extends into underlying soft tissue and can involve muscle and/or bone

A

deep burn injury (previously fourth-degree burn)

52
Q

an itchy rash caused by direct contact with a substance or an allergic reaction to it.

A

contact dermatitis

53
Q

eczema - believed to arise from an abnormal, overactive, inflammatory immune response. It involves both the dermis and the epidermis.
