- The Stratum Granulosum & the Stratum Lucidum.
- The Stratum Corneum.
- The Papillary Layer.
- The Reticular Layer.

What are the parts of the dermis?
The dermis is divided into two layers: the papillary dermis and the reticular dermis. The papillary dermis is the superficial layer, lying deep to the epidermis. The papillary dermis is composed of loose connective tissue that is highly vascular.
What is found in epidermis?
