25
It has all 5 strata, it is found in areas subject to pressure or friction
Thick Skin
26
It covers the rest of the body and is more flexible and than thick skin
Thin Skin
27
It is an area of the skin subjected to friction or pressure
Callus
28
It is the skin over bony prominences structure
Corn
29
It is a group of pigments primarily responsible for skin, hair, and eye color
Melanin
30
These are vesicles which melanocytes produce and package melanin
Melanosomes
31
It is a recessive genetic trait that results from an inability to produce tyrosinase
Albinism
32
It is a condition in which skin turns a reddish hue when the amount of blood flowing increases
Erythema
33
It is a condition where the skin turns to a bluish color due to decrease in blood flow
Cyanosis
34
It is a yellow pigment found in plants it is a source of vitamin A for humans
Carotene
35
It is used for tuberculin skin test, it goes into the dermis
Intradermal Injection
36
It extends into the subcutaneous tissue, example is insulin injection
Subcutaneous Injection
37
It reaches muscle deep into the subcutaneous tissue, it is used for injecting vaccines
Intramuscular Injection
38
It develops by the 5th or 6th month of fetal development, it is unpigmented hair
Lanugo
39
It is pigmented in the near time of birth it is long, coarse
Terminal Hairs
40
These are short, fine, and usually unpigmented, it replaced the lanugo on the rest of the body
Vellus Hairs
41
This is the part of the hair where it protrudes above the surface of the skin
Shaft
42
It is part of the hair that is located below the surface
Root
43
The base of the roots is expanded to form
Hair Bulb
44
It is the central axis of the hair which consists two to three layers of keratin
Medulla
45
It surrounds the medulla and forms the bulk of the hair
Cortex
46
It covers the cortex it is single layered and contains hard keratin
Cuticle
47
It is a tubelike invagination of the epidermis that extends into the dermis
Hair Follicle
48
Hair follicle consists of two parts
Dermal Root Sheath Epithelial Root Sheath
49
It is the portion of the dermis that surrounds the epithelial root sheath
Dermal Root Sheath
50
It is inside the hair bulb that contains a mass of undifferentiated epithelial cells
Matrix
51
It projects from the dermis of the skin into the hair bulb
Hair Papilla
52
Hair increases in length and a new matrix of cells are produced
Growth Stage
53
It is also called spot baldness it involves varying degrees of hair loss and can affect all areas of the body
Alopecia Areata
54
This part of the hair follicle produces goose bumbs
Arrector Pili
55
What are the two types of Sweat Glands
Eccrine Glands Apocrine Glands
56
It produces isotonic fluid that is mostly water that also contains some salts and small amounts of ammonia
Eccrine Sweat Glands
57
These glands are found in the Axillae and genitalia, it is active during puberty as a result of sex hormones, it releases body odor
Apocrine Sweat Glands
58
These are modified eccrine sweat glands located in the ear canal
Ceruminous Glands
59
It is composed of combined secretions of the ceruminous glands and sebaceous glands
Cerumen
60
These are modified apocrine sweat glands located in the breasts, they produce milk
Mammary Glands
61
It is a thin plate consisting of layers of dead stratum corneum cells that contains a hard type of keratin
Nail
62
The nail consists of two parts
Nail Root (covered by skin) Nail Body (visible portion of the skin)
63
It covers the lateral and proximal edges of the nail
Nail Fold
64
It is the nail fold that grows onto the nail body
Cuticle or Eponychium
65
It is a thickened region of the stratum corneum it is beneath the nail edge
Hyponychium
