Layers of the EPIDERMIS (outer to inner layer) Stratum Corneum(SC) Found in the
heel/no nuclei-> Stratum lucidum(SL) absent in thin skin/no nuclei-> Stratum
Granulosm(SGr)->Stratum Germinativum(SGerm) mitosis occurs contains stratum
basale and stratum stratum spinosum
Layers of the skin Epidermis(Keratin/layer of dead cells/no blood flow
Dermis(innermost layer of skin) contains blood vessels/sensory nerve endings/fibrous
connective tissue, Hypodermis
sebum oily secretion by sebaceous glands
arrector pili muscle goosebumps makes hair stand up
dermal papilla Responsible for fingerprints, found between dermis and epidermis
apocrine and eccrine 2 types of sweat glands
Apocrine found in armpits and comes in during puberty smell
Eccrine found on arm/legs etc and most numerous no smell
Pacinian corpuscles deep touching e.g grabbing
Meissner's corpuscles fine touching e.g like wind
simple squamous maximum diffusion(substances pass thru easily) e.g gas exchange in
lungs, alveoli, Blood vessels, lymph vessels
simpe cuboidal secretion/absorption e.gGlands and Kidneys
simple columnar epithelium secretion, and absorption e.g. uterus DI Tract
stratified squamous epithelium function Protects underlying tissues in areas subjected
to abrasion
stratified cuboidal epithelium function protection
