the bod’s miracle wrao
epidermis
cells are produced in the stratum basale
keratinocytes,melanocytes, langerhans cells and merkel cells
squamos cell containing
keratin
cell divide by mitosis and some of the newoly formed cell become the cell of the more superficial strata
stratum basale
keratin fibers and lamellar bodies accumulate
stratum spinosum
keratin fibers and lamellar bodies accumulate
stratum spinosum
keratohyalin and a hard protein envelope form; lammellar bodies release lipids;cell dies
stratum granulosum
keratohyalin and a hard protein envelope form; lammellar bodies release lipids;cell dies
stratum granulosum
dead cells containing dispersed keratohyalin
stratum lucidum
dead cells containing dispersed keratohyalin
stratum lucidum
dead cells with a hard protein envelope; the cells contain keratin and are surrounded by lipids
stratum corneum
transformation if stratum basale cell intostratum corneum cells
keratinzation
nails and external parts of the hair, more durable, do not desquamate
soft keratin
thickened area due to increased number pf layers
callus
thickened area due to increased number pf layers
callus
-cone shaped structure over bony prominences
-extends deep into epidermis
