Protection
Cutaneous Sensation
Blood Reservoir
Excretion
Oil gland
moisturize hair follicle
helps regulate temperature
Skin Color
melanin
froms range of color
made from tyrosine.
Hair
hair follicle receptor
warmth
accumulation of keratin
hair matrix
cells for hair are made
epidermis
layers
stratum basale
2 cells are made
1 cell stays another breaks off and becomes dead cells
rapid division of these cells.
stratum spinosum
prickly layer
tension-resisting protein
second layaer
stratum corneum
Keratin and proteins that accumulate
protect the skin against abrasion and penetration
stratum granulosum
keratohyaline granules
form keratin in the upper layers
lamellar granules
slow water loss
process of keratinization
stratum lucidum
only found in thick skin
dead keratinocytes
cells
keratinocytes
produce keratin
Melanocytes
synthesize the pigment melanin
dendritic cells
arise from bone marrow
surrounding keratinocytes,
tactile epithelial cells
sensory receptor for touch.
