|
Stratum Corneum
|
Mostly squamos, keratinized, get sluffed often, no nucleus
|
|
Stratum Lucidum
|
Only in thick skin, no nucleus
|
|
Stratum granulosum
|
Flattened, nucleated, in layers, many granuoles, membrane coating present (like waterproofing) Also only in thick skin
|
|
Sratum Spinosum
|
Pickle Cells (spiney- spinosum). Spiney because of the desmosomes that connect the cells.- Also has Langerhaans cells, which are dendritic/macrophages the are APC
|
|
Sratum basale
|
Deepest layer. Single layer of tall cuboital keratinocytes. Constantly mitotically active.2 types of cells in basale:Melanocytes and Merkel cells (respond to touch)
|
|
Dermis
|
Papilary layer: gives fingerprints, has capillary loops. Also has Meisner's corpusules (fine touch, two point)Reticular layer: dense and sensory receptors. Free nerve endings. Roots of hair follicles go here. Erector pili muscle is also here.
