Front 18

Melanin

Back 18

Tiny grains of pigment that are produced by melanocytes and deposited into cells in the stratum germinativum layer of the epidermis and in the papillary layers of the dermis. The are two types of melanin: pheomelanin, which is red to yellow in color, and eumelanin, which is dark brown to black.

Papule

Back 22

Also known as a pimple; small elevation on the skin that contains no fluid but may develop pus.

Front 29

Reticular layer

Back 29

Front 30

Sebaceous glands

Back 30

Also known as oil glands; glands connected to the hair follicles.

Front 31

A type of melanin that is red to yellow in color. People with light-colored skin mostly produce pheomelanin. There are two types of melanin, the other type is eumelanin.

Front 32

Secretory coil

Back 32

Coiled base of the sudoriferous gland.

Back 34

Fibers of the sensory nerves that react to hot, cold, touch, pressure and pain.

Front 35

Secretory nerve fibers

Back 35

Fibers of the secretory nerve that are distributed to sudoriferous and sebaceous glands.

Front 36

Stratum corneum

Back 36

Also known as the horny layer; outer layer of the epidermis.

Front 37

Stratum germinativum

Back 37

Also known as the basal cell layer; deepest live layer of the epidermis that produces new epidermal skin cells and is responsible for growth.

Front 38

Stratum granulosum

Back 38

Also known as the granular layer; layer of the epidermis composed of cells that look like granules and are filled with keratin; replaces called shed from the stratum corneum.
