Flashcards in The Dermis Deck (37):
1

Histamine

Causes swelling

2

Technical term for swelling

Edema

3

Also know as the dermal matrix...made up of proteins and GAGS

Ground substance

4

Glycosaminoglycans

Gel like substance that is made up of water and proteins, it maintains water balance and gives support to the dermis

5

Can hold 100x it's own weight in water

Hyaluronic acid

6

Elastin

Makes up 15% of the dermis and gives the skin it's elasticity

7

Cicatrix (scar)

When elastin is damaged and replaced with collagen

8

Makes up 5% of the dermis and creates a support system or framework for the other structures found within the dermis

Reticulan

9

Subcutaneous

Also known as the hypodermis and subcutis

10

Makes up 70% of the dermis and gives support (tone) to the skin

Collagen

11

Sebacesous glands

Produces sebum which lubricates the surface of the skin and slows down TEWL

12

Excretes waste and toxins through perspiration

Sudoriferous glands

13

Hair follicle

Protects against the elements, helps with regulation of body temp, aids in the transportation of sebum onto skin

14

Responsible for the inflammatory response

Produces two chemicals: histamine and heparin

Mast cell

15

Location where small arteries and veins come together for A gaseous exchange

Looped capillaries

16

Fat cells

Used for insulation and energy reserve

17

Gel like substance that is made up of water and proteins

Gags

18

Fibroblast

Specialized cell that produces collagen

19

Type of white blood cell that produces antibodies

Lymphocyte

22

Structure in the dermis used for insulation and energy reserve

Fat cells

23

Blood vessels

Transport blood which carries oxygen and nutrients to the cells and removes waste products

24

What does vitamin c stimulate?

Fibroblast to produce more collagen

25

Also know as the subcutis and hypodermis

Subcutaneous

26

Collagen

Makes up 70% of the dermis and gives support to the skin (tone)

27

Filters and removes waste from the extra interstitial fluid and returns it back to the blood stream

Lymph vessels

28

Transports blood which carries oxygen and nutrients to the cells and removes waste products

Blood vessels

29

Dermal papillae

Cone like projections that contain looped capillaries and tactile corpuscles

30

Regulates body temperature through insulation
Cushions and protects the bones and internal organs
Stores excess energy
Stores fat soluble vitamins a d e k
