CONGENITAL DISORDERS of the blood vessels in the dermis
Birthmarks
26
where the skins RESTS AND ATTACHES it to underlying BONE AND MUSCLE and supplies it with blood vessels and nerves.
Subcutaneous Tissue
27
not part of the skin… (Aww xoxad di belong)
Hypodermis
28
includes adipose tissue that contains about half the body’s stores lipids *can be used to estimate total body fat *21 to 30% in female ; 13% to 25% in male
Subcutaneous Tissue
29
found everywhere on the skin, except on the palms, soles, lips, nipples, parts of the genitalia and the distal segments of the fingers and toes
Hair
30
is produced in the hair bulb, which rests on the papilla
Hair
31
consists of COLUMNS of DEAD KEARTINIZED epithelial cells
Hair root and shaft
32
growth stops and the hair is held in the hair follicle
Resting Stage
33
30 days/105 days; scalp hair 3 years/1-2years
Eyelashes
34
melanin MELANOCYTES WHICH OCCURS IN THE HAIR BULD by the same method as in the skin.
Hair Color
35
smooth muscles cell associated with each hair follicle that causes “goose bumps”
Arrector Pili
36
2 major Glands of the skin
*Sebaceous Gland *Sweat Gland
37
simple, branched acinar glands • connected by a duct to the superficial part of a hair follicle *Found in the dermis
Sebaceous Gland
38
an OILY WHITE SUBSTANCE RICH IN LIPIDS;holocrine secretion; lubricates the hair and the surface of the skin
Produces SEBUM
39
Two types of Sweat Glands
*Eccrine Glands *Apocrine Glands
40
> simple , coiled, tubular gland; RELEASE SWEAT BY MEROCRINE SECRETION • numerous in palms and soles • secretion that is mostly water with few salts
Eccrine
41
Simple, coiled, tubular gland that PRODUCE A THICK SECRETION RICH IN ORGANIC SUBSTANCE. merocrine secretion • armpits and genitalia • active in puberty • body odor
Apocrine
42
THIN PLATE, consisting of layers of dead stratum corneum cells that contains a VERY HARD TYPE OF KERATIN.
Nails
43
VISIBLE part of the nail *Distal part of the nail
Nail Body
44
Part of the nail that is COVERED by the skin *Proximal part of the nail
Nail Root
45
The LATERAL and PROXIMAL EDGES of the nail are covered by skin called?
Nail Fold
46
the edges of the nail are held in place by the?
Nail Groove
47
The stratum corneum of the nail fold grows onto the nail body as the? *EXTEND onto the nail body
Cuticle
48
Beneath the free edge of the nail body is the? *A thickened region of the stratum corneum.
Hyponychium
49
The nail root extends distally from the?
Nail Matrix
50
The nail also attaches to the underlying________ *Located between the NAIL MATRIX and the HYPONYCHIUM.
Nail Bed
51
Grows without resting stage ( sheesh di napapagod)
Nails
52
a WHITISH CRESCENT shaped area at the base of the nail. appears white because the blood vessels do not show through the thicker nail matrix
Lunula
53
A YELLOWISH SKIN COLOR occurs when EXCESS bile pigments accumulate in the blood. *Liver damage
Jaundice
54
The bacteria release a toxin into the blood that causes the PINK-RED RASH for which this disease was named.
Rashes and Lesions
55
is affected by nutritional status. VITAMIN A. DEFICIENCY causes the skin to produce excess keratin and assume a characteristic sandpaper texture, whereas iron-deficiency anemia causes the nails to lose their normal contour and become fl at or concave (spoon-shaped).
The condition of the skin, hair, and nails
56
injury to a tissue caused by heat, cold, friction, chemicals, electricity or radiation
Burns
57
Partial thickness burns damage only the epidermis
First Degree Burn
58
damage the epidermis and dermis. Minimal dermal damage causes redness, pain, edema, and blisters.
Second-Degree Burns
59
FULL-THICKNESS burns, destroys the epidermis, the dermis and usually the underlying tissues
Third-Degree Burns
60
Types of Skin cancers
*Basal Cell Carcinoma *Squamoous Cell Carcinoma *Melanoma
61
composed of dense collagenous connective tissue containing fibroblasts, adipocytes and macrophages.
Dermis
