These cells synthesize skin pigment to give skin and hair its color; found in the deepest layer of the epidermis:
Langerhans cells
The cells are macrophages in the epidermis that help activate our immune system.
Merkel cells
melanocytes
keratinocytes
Langerhans cells
These cells function as sensory receptors for touch in the epidermis.
