Superficial región
Epitelial tissue and avascular
Four cell types in epidermis
Keratinocytes

Layers of skin
3 stratum granulosum
Granular layer
4-6 cells thick's but cells are flattened
Cell appearance change
Cells above layer die
4 stratum spinosum
Several cell layer thick
Prickly layer
Keratinocytesin this layer are spiked = prickle cells
5 stratum basale
Is the basal lager
Consists of a single row of cells that actively divide 1 mitotic)
Firmly attached to dermis
Daughter cell journey from basal lager to surface, taking 25-45 day to reach surface
Cons dies as it moves toward surface
Deepest of all epidermal layer (base layer)
2 stratum lucidum
