24
Q

which layer of the skin connects to the underlying structures of the body

Study These Flashcards
A

Hypodermis (subcutaneous layer)

25
This layer of the skin is composed of loose connective tissue and adipose tissue
Hypodermis (subcutaneous layer)
26
what part of the skin is liposuction done
Hypodermis (subcutaneous layer)
27
what are the accessory stuctures of the skin
* Hair * Nail * Glands
28
what is the function of your hair
1. Protects eyes from dust, perspiration, & sunlight 2. temperature regulation 3. traps particles in nasal pathways 4. helps with light tough sensation
29
how is the color resulted
it is genetically controlled and determine by the amount of melanin
30
what are the 3 main parts of the hair anatomy
Root → extends from the dermis to the surface where follicles are Shaft → above the skin surface Hair Bulb → where the follicle is planted
31
what is the smooth muscle that contracts and makes the hair "stand up"
Arrector Pili Muscles
32
what is the partial or complete lack of hair called
Alopecia
33
what are the 3 anatomical structures of the nail from superficial to most deep?
1. Free Edge 2. Nail Root 3. Nail Body
34
what part of the skin are the sweat glands located?
The Dermis
35
what are the two sweat gland structures
1. Apocrine 2. Eccrine
36
This sweat gland is located around the hair follicles in the armpit and genitals
Apocrine
37
This sweat gland is the stinky sweat gland
Apocrine
38
the most numerous sweat gland and is important for temperature regulation
Eccrine
39
what is the function of the sebaceous gland
it lubricates and waterproofs the skin
40
this gland grows where the hair grows
sebaceous gland
41
this skin cancer is slow growing, its malignant tumor of epithelial cells and can spread if let untreated
Squamous Cell Carcinoma
42
This skin cancer is the most common type of skin cancer and is less likely to metastasize
Basal Cell Carcinoma
43
this type of skin cancer is the most serious form, & spreads from dark pigmented moles
Melanoma
44
what is the ABCDE rule
* Asymmetry * Borders * Color * Diameter * Evolving
45
what are the 12 regions of the rule of 9's
1. Whole head (9%) 2. Chest (9%) 3. Abdomen(9%) 4. Left Anterior Leg (9%) 5. Left Posterior Leg (9%) 6. Right Anterior Leg (9%) 7. Right Posterior Leg (9%) 8. Whole Left Arm (9%) 9. Whole right arm (9%) 10. Upper Back (9%) 11. Lumbar (9%) 12. Genitals (1%)
46
This type of burn is red, minimal pain & destruction, usually leads to sunburn
1st degree
47
This type of burn is painful, edema/swelling, leads to blisters and involves the deep epidermal layer
2nd Degree burn
48
This type of burn is a full thickness burn, complete destruction of epidermis, dermis, sensory receptors (no pain), and has a great risk of infection
3rd Degree Burn
49
This type of burn is a full thickness that extends below the subcutaneous tissue to reach muscle or bone
4th Degree Burn
50
what are some treatments for 4th degree burns
