There are four layers of what one consider to be skin, from superficial to deep, they are epidermis, dermis, hypodermis, and deep fascia.
Epidermis is formed by stratified squamous epithelial tissue, keratinized type:
Dermis has two layers: papillary dermis and reticular dermis. The deeper reticular dermis is composed of mostly dense irregular connective tissue that makes it resistant to pulling forces in many directions. Structures that can be found in the dermis are: Messiner’s corpuscle, Pacinian corpuscle, hair follicle, arrector pili, sebaceous (oil) gland, and sweat gland.
Hypodermis is composed of mostly adipose tissue. It is also known as the subcutaneous layer and superficial fascia.
Under the hypodermis would be the deep fascia that wraps around the skeletal muscle.
