Question 9

stratum basale

Answer 9

deepest

stem cells producing keratinocytes

Question 10

stratum spinosum

Answer 10

prickle cell layer
8-10 cell layers
polyhedral cells with cytoplasmic processes called spines -> contact neighboring cells by desmosomes

Question 11

stratum granulosum

Answer 11

3-5 cell layers
diamond shape cells
function as glue

Question 12

stratum lucidum

Answer 12

2-3 layers
present in thicker skin usually in palms or soles
thin clear layer consisting of eleidin –> product of keratohyalin

most superficial
20-30 cell layers
uppermost layer made of dead keratinocytes
varies most in thickness

callous skin = thicker
