to Module 1
This illustration shows
the different layers of skin:
- The bottom layer is
made up of fat cells. These fat cells form the subcutaneous tissue.
- Above the fat cells,
in the reticular layer, hair follicles and sweat glands begin and
continue through the remaining layers to the surface.
- A
papillary/reticular dermal interface separates the reticular layer and
the layer above it, which is the papillary layer.
- Above the papillary
layer is the uppermost layer, the epidermis. The epidermis is
comprised of squamous cells and melanocytes interspersed through basal
cells.
