dermis

5

which is the fat layer?

subcutaneous / hypodermis

6

terminal - coarser, thicker

11

finger nails grow how long in a day?

0.1 mm

12

True or False. Sweat glands Produce a fatty substance that is secreted onto the skin surface through the hair follicles

False: sebaceous glands

13

what are the 2 types of sweat glands

1. eccrine - control body temp, secrete onto skin surface

2. apocrine - in axillary & groin, open onto hair follicle

14

What is used in screening moles for melanoma?

A- asymmetry
B- borders-- irregular
C- change in color
D- diameter
E- elevation or enlargement

15

what is turgor

speedc with which, skin returns into place

16

what is mobility

lift skin and note ease with which it lifts up

17

what is A slightly but uniformly pigmented macule or patch with a somewhat irregular border.

Café-Au-Lait Spot

18

what is vitiligo?

Depigmented macules appear on the face, hands, feet, extensor surfaces.
Brown pigment is normal skin while the pale areas are vitiligo

19

where is jaundice is reliably and most easily seen?

sclera

20

what is the slapped cheek disease

fifth disease

21

what is an immune-mediated disease that affects the skin. It occurs when the immune system mistakes the skin cells as a pathogen, and sends out faulty signals that speed up the growth cycle of skin cells.
Presents as silvery scaly lesions

psoriasis

22

what is eczema?

skin rashes that are characterized by redness, skin edema (swelling), itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding.
An allergic disease associated with asthma.

23

lupus malar rash

24

what is plaque?

A patch of closely grouped papules

25

what is a palpable solid lesion with distinct edges

nodule

26

what is A vascular reaction involving the deep dermis or subcutaneous or submucosal tissues, representing localized edema caused by dilatation and increased permeability of the capillaries, and characterized by the development of giant wheals

angioedema

27

A small raised lesion filled with clear fluid

vesicles

28

another name for blister

bulla

29

life threatening skin conditions that are Thought to be a hypersensitivity complex

erythema multiforme - Stevens–Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN)

30

what are scales?

dry, horny build-up of dead skin cells that often flakes off the surface

31

what is lichenification

Rough, thick epidermis with exaggerated skin lines.

32

what are Linear or punctate erosions

excoriation

33

stages of pressure ulcer

Stage 1: Skin is not broken but is red or discolored.
Stage 2: The epidermis is broken, creating a shallow open sore.
Stage 3: The break in the skin extends through the dermis into the subcutaneous and fat tissue.
Stage 4: The breakdown extends into the muscle and can extend to the bone. Usually lots of dead tissue and drainage are present.

34

what are The least serious burns are those in which only the outer layer of skin is burned, but not all the way through.

1st degree

35

When the first layer of skin has been burned through and the second layer of skin (dermis) also is burned, the injury is called a second-degree burn.

2nd degree

36

The most serious burns involve all layers of the skin and cause permanent tissue damage. Fat, muscle and even bone may be affected. Areas may be charred black or appear dry and white. Difficulty inhaling and exhaling, carbon monoxide poisoning, or other toxic effects may occur if smoke inhalation accompanies the burn.

3rd degree

37

what is commonly known as flesh-eating disease or flesh-eating bacteria syndrome

necrotizing fasciitis
