Epidermis
Collagen and elastic tissues. All sensory nerve endings, sweat glands, blood vessels, hair follicles, and sebaceous glands
Dermis
2 layers of the dermis.
Papillary dermis and reticular dermis.
Temperature regulation, control of fluid loss/intake, production of vitamin D, secretion of lubricating oils, and defense against disease
Skin Functions
Involve the epidermis. Red and painful but heals readily without scaring.
Superficial Burns (1st degree)
Involves the epidermis and part of dermis. Usually heals within 10 days by regeneration from the edges. Easily infected.
Superficial partial thickness burn (2nd degree).
Involves epidermis and deep dermal layers. Most hair follicles and sweat glands will be damaged, usually heals within 3 to 5 week.
Deep Partial thickness burn (3rd degree).
Destroys epidermis dermis and often subcutaneous tissue, eschar is present and do not heal without surgical grafts.
Full thickness burn (4th degree).
Involves complete destruction of all tissue from epidermis down to and through the subcutaneous tissue, extensive surgery is required. Due to contact with a flame, hot liquid or electricity.
Subdermal burn
