Answer 2

barrier function

Question 3

fluid between epidermal cells

Answer 3

intercellular matrix

Question 4

a hormone that stimulates skin cells to reproduce and heal

Answer 4

epidermal growth factor (EGF)

Question 5

cell stimulators

Answer 5

fibroblasts

Question 6

small, involuntary muscles in the base of the hair follicles that cause goose bumps

Answer 6

arrector pili muscle

Question 7

guard cells of the immune system that sense unrecognized foreign invaders, such as bacteria, and then process these antigens for removal through the lymph system.

Answer 7

langerhans immune cells

Question 8

tube like opening for sweat glands on the epidermis

Answer 8

pores

Question 9

oil that provides protection for the epidermis from external factors and lubricates both the skin and hair

Answer 9

sebum

Question 10

fiberous protein of cells that is also the principal component of skin, hair, and nails; provides resiliency and protection

Answer 10

keratin

Question 11

fiberous protein of cells that is also the principal component of skin, hair, and nails; provides resiliency and protection

Answer 11

keratin

Question 12

outermost layer of skin; a thin, protective layer with many cells, mechanisms and nerve endings
- It is made up of 5 layers:
stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum germinativum

Answer 12

epidermis

Question 13

AKA the derma, corium, cutis, or true skin;
support layer of connective tissue, collagen, and elastin below the epidermis

Answer 13

dermis

Question 14

AKA hypodermis;
subcutaneous adipose (fat) tissue located beneath the dermis; a protective cushion for the outer skin

Answer 14

subcutaneous layer

Question 15

deeper layer of the dermis that supplies the skin with oxygen and nutriendsl contains fat cells, blood vessels, sweat glands, hair follicles, lymph vessels, arrector pili muscles, oil glands and nerve endings

Answer 15

reticular layer

Question 16

deeper layer of the dermis that supplies the skin with oxygen and nutriendsl contains fat cells, blood vessels, sweat glands, hair follicles, lymph vessels, arrector pili muscles, oil glands and nerve endings

Answer 16

reticular layer

Question 17

top layer of the dermis next to the epidermis

Answer 17

papillary layer

Question 18

AKA granular layer; layer of the epidermis composed of cells filled with keratin that resemble granules; replaces cells shed from the stratum corneum

Answer 18

stratun granulosum

Question 19

AKA basal cell layer; active later of the epidermis above the papillary layer of the dermis; cell mitosis takes place here that produces new epidermal skin cells and is responsible for growth

Answer 19

stratum germinativum

Question 20

AKA basal cell layer; active later of the epidermis above the papillary layer of the dermis; cell mitosis takes place here that produces new epidermal skin cells and is responsible for growth

Answer 20

stratum germinativum

Question 21

stratum lucidum

Answer 21

clear, transparent layer of the epidermis under the stratum corneum; thickest on palms of hands and soles of feet

Question 22

AKA spiny layer, layer of the epidermis above the strtum germinativum (basal) layer containing desmosomes, the intercellular connections made of proteins

Answer 22

stratum spinosum

Question 23

white blood cells that have enzymes to digest and kill bacteria and parasites; respond to allergies

Answer 23

leukocytes

Question 23

white blood cells that have enzymes to digest and kill bacteria and parasites; respond to allergies

Answer 23

leukocytes

Question 24

protein fiber found in the dermis; gives skin its elasticity and firmness

Answer 24

elastin
