Q

______ _______ ______makes the dermis tough.

A

Collagen protein fibers

30
Q

It is the uneven upper dermal region.

A

Papillary Layer

31
Q

finger like projections from the superior surface of
the papillary layer that indents the epidermis above.

A

Dermal papillae –

32
Q

It is the deepest skin layer of dense irregular connective tissue,
containing blood vessels, sweat glands, oil glands and phagocytes.

A

Reticular Layer

33
Q

It is a layer of loose subcutaneous adipose tissue found deep into
the dermis and is not considered as part of the skin but it anchors
the skin to the underlying organs, muscle or bone.

A

Hypodermis

34
Q

It serves as a shock absorber and insulates the deeper tissues from
extreme temperature changes occurring outside the body.

A

Hypodermis

35
Q

It also supplies the skin with blood vessels and nerves.

A

Hypodermis

36
Q

has minor protective functions and help keep foreign
particles out of the respiratory tract

A

Hair

37
Q

found everywhere on the skin except the palms, soles, the lip,
the nipples, parts of the external genitalia, and the distal segments
of the fingers and toes.

A

Hair

38
Q

protrudes above the surface of the skin

A

Shaft

39
Q

located below the surface of the skin

A

Root

40
Q

keratinized epithelial cells arranged in three concentric layers:

A

Medulla
Cortex
Cuticle

41
Q

a single layer of cells also containing hard keratin and
covers the cortex.

A

Cuticle

42
Q

the central axis of the hair and it consists of two or three
layers of cells containing soft keratin.

A

Medulla

43
Q

surrounds the medulla and forms the bulk of the hair.

A

Cortex

44
Q

The cells of the_____contain hard keratin

A

Cortex

45
Q

a tube-like invagination of the epidermis that extends into
the dermis, where hair develops and grows

A

Hair follicle

46
Q

expanded portion at the lower end of the hair root and forms
the base of the hair follicle.

A

Hair bulb

47
Q

The growth of a hair results from the
proliferation of cells of the_____.

A

hair bulb

48
Q

a mass of undifferentiated epithelial cells inside the hair bulb that produces the actual hair

A

Matrix

49
Q

a dermis projection into the hair bulb, within the hair papilla are blood vessels that provide nourishment to the cells of the matrix

A

Hair papilla

50
Q

smooth muscle extending from the hair follicle to the papillary layer of the dermis.

A

Arrector pili muscle

51
Q

During contraction, it pulls the follicle
into a more perpendicular position.

A

Arrector pili muscle

52
Q

These secrete materials onto the skin surface

A

Glands

53
Q

located in the dermis and found all over
the skin except on the palms of the hands and the soles of the feet.

A

Sebaceous glands

54
Q

produced by the sebaceous glands which is a mixture of
oily substances that lubricates the skin making it soft and moist as
well as preventing the hair from becoming brittle.

A

Sebum

55
Q

widely distributed in the skin
and secretes sweat through pores to help in thermoregulation.

A

Sweat glands

56
Q

most common type and found all over the body’s skin but are numerous in the palms of the hands and soles of the feet.

A

Eccrine sweat glands

57
Q

confined to the axilla, around the anus,
and genital areas

A

Apocrine sweat glands

58
Q

It is a thin plate consisting of layers of dead stratum corneum cells
that contain a very hard type of keratin

A

Nail

59
Q

It is a modification of the epidermis with its root embedded in the skin

A

Nail

60
Q

proximal portion covered by skin.

A

Nail root

61
Q

distal visible portion of the nail.

A

Nail body

62
Q

skin that covers the lateral and proximal edges of the nail

A

Nail fold

63
Q

holds in place the edges of the nail.

A

Nail groove

64
Q

the exposed prolongation of the nail fold’s
stratum corneum that grows onto the nail body

A

Cuticle

65
Q

a thickened region of the stratum corneum found beneath the free edge of the nail body

A

Hyponychium

66
Q

tissue where the nail root extends.

A

Nail matrix

67
Q

tissue under the nail and is located between the nail matrix and the hyponychium

A

Nail bed

68
Q

A small part of the nail matrix that is seen through the nail
body as whitish crescent-shaped area at the base of the nail.

A

Lunula

69
Q

attract and bind water and help the
skin stay hydrated

A

Collagen fibers

70
Q

It is the deepest layer of the epidermis and lies closest to the dermis
and contains the only epidermal cells that receive adequate
nourishment via diffusion of nutrients from the dermis.

A

Stratum Basale
