This is about the cells of the oral epithelium which are called the non keratinocytes
have colour coded the layers to make it easy to remember
Blue for basal cells
Pink for prickle cells
Greenfor granular cells

These cells do not produce keratin so non keratinocytes
Langerhans cells
Merkel cells
Melanocytes
Antigen presenting cells
Function of each type of cells ,their importance
how their levels vary during oral pathological conditions
