What are the main structural features of the epidermis?
The epidermis has a complex structure designed to protect from the environment. It has an undulating surface with cross-crossing ridges and valleys, with invaginations due to follicles and sweat duct ostia. Epidermis is thickest on palms and soles, and thinnest on eyelid and scrotum.
What are the layers of the skin describe each?
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What happens in each layer of the epidermis?
The outermost layer of the epidermis (stratum corneum) holds in water and keeps your skin hydrated and healthy. Producing new skin cells. New skin cells develop at the bottom layer of your epidermis (stratum basale) and travel up through the other layers as they get older.
What are the functions of the epidermis layers?
The epidermis: Acts as a protective barrier: The epidermis keeps bacteria and germs from entering your body and bloodstream and causing infections. It also protects against rain, sun and other elements. Makes new skin: The epidermis continually makes new skin cells.
What are the layers of the epidermis from superficial to deep?
It does not have any blood vessels within it (i.e., it is avascular). Skin that has four layers of cells is referred to as “thin skin.” From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum.
