composed of layers (strata)

Answer 11

epidermis

Question 12

two kinds of tissue compose the skin

Answer 12

epidermis and the dermis

Question 13

anchors the skin to underlying organs
not technically part of the integumentary system
composed mostly of adipose tissue
serves a shock absorber to insulate deeper tissues

Answer 14

strata of the epidermal

stratum granulosum
stratum spinosum
stratum basale (deepest)

Question 16

deepest layer of the epidermis

Answer 16

stratum basale

-daughter cells are pushed upward to become the more superficial layers

Answer 17

stratum basale
