Skin Flashcards
Stratum Corneum
Dead cells with a hard protein envelope; the cells contain keratin and are surrounded by lipids.
TOP SUPERFICIAL
Stratum Lucidum
Deadcells containing dispersed keratohyalin
2ND SUPERFICIAL
Stratum granulosum
Keratohyalin and hard protein envelope form; lipids are released; cells die
3RD SUPERFICIAL
Stratum spinosum
Keratin fibers and lameliar bodies accumulate
2nd DEEP
Stratum basale
Cells divide by mitosis and some of the newly formed cells become the cells of the more superficial strata
