Test 2: Dermis And Membranes

Front 1

Dermis Papillary Layer

Back 1

superficial layer of dermis, areolar tissue, produce fingerprints and other ridges, allows heat to radiate to the skin, contains free nerve endings and touch receptors

Front 2

Dermis Reticular Layer

Back 2

Deepest skin layer, dense irregular ct; contains arteries, veins, sweat and subaceous glands, and pressure receptors

Front 3

Arrector Pili Muscle

Back 3

small muscle that connects each hair follicle to he papillary layer of dermis. When muscle contracts during cold or freight, hair follicles are pulled upright producing goosebumps

Front 4

Sebaceous (Oil) Glands

Back 4

found all over except on palms and soles, ducts empty into a hair follicle, secrete sebum which is an oily substance that acts as a lubricant to keep skin soft and moist, keeps hair from becoming brittle

Front 5

Eccrine sweat glands

Back 5

produce sweat primarily of water, salt, and urea. body's cooling system

Front 6

Apocrine sweat glands

Back 6

found in axillary and genital areas, secrete milky protein and fat rich substance containing salt, water, and urea. Good nutrient for microorganisms on skin

Front 7

Mucous Membrane

Back 7

epithelial cells resting on loose ct called the lamina propria, lubricates lines all cavities open to exterior; respiratory, digestive, and urogenital tracts

Front 8

Cutaneous Membrane

Back 8

the skin, a dry membrane with keratinizing epithelium. protects and keeps skin moist. Contains sweat glands.

Front 9

Serous Membrane

Back 9

epithelial membranes composed of simple squamous epithelium on areolar connective tissue. parietal layer lines body cavity, visceral layer covers organs, lubricates and reduces friction between organs
