25
There is limited cell division in this tissue
stratum Spinosum
26
This tissue is spindle-shaped when hydrated but is flat when dehydrated. There is also limited cell division in this tissue portion
stratum Spinosum
27
The highly mitotic cells of the epidermis are found here which replaced the old cells
stratum Basale / stratum Germinativum
28
This tissue is the deepest portion of the epidermis
stratum Basale / stratum Germinativum
29
This tissue has high mitotic activity and is the deepest portion of the epidermis
stratum Basale / stratum Germinativum
30
Nerve endings are found in the?
Dermal papilla
31
Four epidermal cells
Melanocytes Keratinocytes Merkel's cells Langerhans' cells
32
This cell is the pigment melanin (gives pigment)
Melanocytes
33
This cell is usually found at the area of the stratum Basale / stratum Germinativum
Melanocytes
34
This cell is usually found at the area of the stratum Basale / stratum Germinativum and gives pigment (pigment melanin)
Melanocytes
35
This cell produces keratine
Keratinocytes
36
This cell is found on most layers of the dermis (stratum Corneum, stratum Lucidum, stratum Granulosum)
Keratinocytes
37
This cell is found on most layers of the dermis (stratum Corneum, stratum lucidum, stratum Granulosum)
Keratinocytes
38
This cell detects light touch and pressure
Merkel's cells
39
This cell is part of the immune system
Langerhans' cells
40
This is the waterproofing of the epidermis
Keratinization
41
This is when cells die and produce the outer layer that resist abrasion and forms the permeability layer
Keratinization
42
This is the waterproofing of the cells and when the cells die, it produces the outer layer that resists abrasions and form a permeability layer
Keratinization
43
The lipid and protein found in the the stratum Corneum
Intercellular lipid Keratin
44
Subcellular structure that is found in the stratum Lucidum
Lamellar body
45
Subcellular structure found in the stratum Lucidum that releases lipids
Lamellar body
46
What does the lamellar body releases?
Lipids
47
These can be found in the stratum Granulosum
Protein envelope Keratohyalin granules
48
These can be found in the stratum spinosum
Lipid-filled lamellar body Keratin fiber
49
These can be found in the stratum Basale / stratum Germinativum
Desmosome Hemidesmosomes Basement membrane
50
What layer is plump if it is filled with lipid but flat if not?
stratum Spinosum
51
Two layers of the dermis
Superficial layer Deeper reticular layer
52
This layer is underneath the dermis and is made up of loose connective tissue
Superficial layer
53
This layer is made up of dense connective tissue and is responsible for the formation of striae (stretch marks)
Deeper reticular layer
54
This layer is made up of connective tissue fibers, subcutaneous fat, adipose cells, and contains macrophages
Hypodermis
55
The accessory skin structures
Hair Nails Glands (sebaceous glands, sudoriferous glands)
56
Two types of sudoriferous glands
Merocrine sweat glands Apocrine sweat glands
57
The gland secretory portion is intact thus, producing sweat within the cells which is secreted by the cells at the secretory portion then is transmitted to the duct into the ski
Merocrine sweat glands
58
The gland secretory portion is apart thus, becomes the secretion itself. thus, it buds off and enters the duct to the skin.
Apocrine sweat glands
59
This is found above the skin surface
Hair shaft
60
This is known as the base of the hair root and the area where the hair is initially formed
hair bulb
61
The gland is connected to the hair follicle to lubricate the hair shaft to give it a shiny appearance and give protection to the scalp from any bacterial or fungal infection
Sebaceous glands
62
These muscles are connected to the hair follicle and gives that goosebump appearance
Arrector pili
63
Three concentric layer of the hair
Medulla Cortex Cuticle
64
Three concentric layer of the hair
Medulla Cortex Cuticle
65
The dilated portion of the hair root
Hair bulb
66
The central axis of the hair
Medulla
67
This forms the bulk of hair
Cortex
68
This forms the hair surface
Cuticle
69
Three dense connective tissue that gives more protection to hair structure
Internal epithelial root sheath External epithelial root sheath Dermal root sheath
70
Anatomy of the nail
Nail root is proximal Nail body is distal
71
Growth of nail is
Continous
72
What produces the nails?
Nial root
73
The nail root is made up of?
Dead cells
74
This area of the nail is made up of dead cells
Nail root
75
This gland produces sebum and oils the hair and skin surface
sebaceous glands
76
this gland is commonly found in the palms, soles, forehead, axillae, genitalia, and around the anus
Sudoriferous glands
77
This gland secretes earwax
cerumonous
78
This gland produces milk
Mammary glands
79
What does the sebaceous glands produces
Sebum
80
What is the purpose of sebaceous glands
Oils hair and skin surface
81
what does the ceruminous gland secretes?
Earwax
82
What does the mammary gland produce
Milk
83
Also known as the accumulation of keratin
Keratinization
84
Produces upper layer of cells of epidermis, hair, and nails
Keratinization
85
Two main types of glands in skin
Sebaceous glands (Oily) Sudoriferous glands (watery)
