Flashcards in Unit 1: Lecture 2 Self-study Deck (12):
1

Functions of skin (PASTE)

Protection
Absorption
Sensation
Temperature
Excretion

2

Layers of the skin (3)

1. epidermis - vegetative intermitotics with a keratinized layer
2. dermis - (papillary/superficial) papillae that carry vasculature to epidermis, and (reticular/deep) a network of collagen elastic fibers
3. Tela subcutanea - panniculus adiposis (layer of fat) and stratum fibrous (superficial fascia)

3

Hair

contained in hair follicle, and consists of keratinized epithelium

4

Arrector Pili

smooth muscle coursing from the root of the hair follicle to the dermis

under sympathetic control

5

Sebaceous Gland

Absent from palms of hands and soles of feet

Sebum production can clog hair follicle, causing acne

Since entire cell is lost in secretion, it is called a "holocrine gland"

6

Sweat Gland

absent from glans of penis and labia minor

"eccrine gland" because none of cell is secreted

large "apocrine glands" (secrete some of cell) around anus and armpit

7

Nails

keratinized epithelium produced at the base of the nail bed

8

Mammary Gland boundaries

Superior: 2nd or 3rd rib.

Inferior: 6th or 7th costal cartilage.

Lateral: Anterior axillary fold (identify on yourself).

Medial: Lateral border of sternum.

9

Nipple

Surrounded by areola and is found at 4th rib

10

Portions of mammary glands (2)

1. parenchyma (functional part)
2. stroma (supportive, connective tissue part)

11

Radical Mastectomy

surgery that is done after breast biopsy

12

Axillary Lymph Node Groups (5)

1. lateral group (around the axillary artery)
2. central group
3. pectoral group
4. subscapular group
5. apical group
