Front 1

epidermis

Back 1

stratified squamous epithelium, avascular

Front 2

stratum germinativum

Back 2

deepest layer of the epidermis, constantly dividing into daughter cells

Front 3

stratum corneum

Back 3

outermost layer of the epidermis consisting of dead keratinized cells

Front 4

basment membrane

Back 4

seperates the two parts of the integument, layer of glycoproteins

Front 5

dermis

Back 5

dense irregular connective tissue, composed of collagen and elastic fibers

Front 6

fibrocytes

Back 6

secrete and maintain teh collagen fibers

Front 7

superficial fascia

Back 7

consists of loose bundles of collagen and elastic fibers and the site of lipocytes.

Front 8

deep fascia

Back 8

below superficial fascia, thin layers of collagen material covering and tightly adherent to underlying muscles. also merges with tendons and ligaments and surrounds bundles of blood vessels and nerves

Front 9

exocrine glands

Back 9

retain connection to the epithelial surface

Front 10

endocrine glands

Back 10

lose their connection to the epithelial surface, hormones

Front 11

sudoriferous gland

Back 11

long, coiled tubular glands that extend deep into dermis. purpose is to secrete water onto the surface of the epidermis

Front 12

holocrine

Back 12

produce and oily material that is thought to keep hairs pliable

Front 13

matrix

Back 13

at the bottom of each hair follicle, a mass of mitotically active cells; produces daughter cells, become keratinized

Front 14

sebacuous gland

Back 14

secrete and oily substance that functions in part to keep hair pliable

Front 15

arrector pili muscle

Back 15

attached to a hair follicle by one end and to the upper dermis by the other, bundle of muscle fibers, allows hair to stand uprights

Front 16

dermatomes

Back 16

a specific region of skin innervated by a specific spinal cord level

Front 17

Nerves

Back 17

found in both the dermis and epidermis
