Where do you find keratinocytes and dendritic cells?
Stratum spinosum
Where do you find tactile cells and melanocytes
basal layer
What cells do you find in stratum spinosum
Keratinocytes and Dendritic cells
What cells do you find in basal layer
melanocytes and tactile cells
What do keratinocytes do
Most abundant layer in epidermis- produce keratin (protein), antibiotics, enzymes
What do dermal papallae do
- Increase surface area, gas exchange
-Adhere to epidermis - Lie on finger prints (increase gripping)
What do reticular dermis do
- Nerve endings, blood vessils, glands
Hypodermis functions
- Increase insulation
- Anchor skin to structures (protect)

Everywhere but palms and bottom of feet
Eccrine vs apocrine gland
- Eccrine makes true sweat, apocrine makes pheromone sweat.

Ductless- secrete hormones directly into tissue fluid
Exocrine gland
- Carry products to epithelial surface

Hyperopic eye problem
Difficult see up close. Eye too short, focused point behind retina.
Myopia problem
Cant see far. Eye too long, focus in front of retina
