Integumentary System

is the deepest layer of the epidermis, the topmost layer of skin. It's responsible for the continuous regeneration of skin, and is made up of a single layer of cells that are constantly dividing and moving upwards.

• stratum basale

• stratum spinosum

• stratum granulosum

• stratum corneum

• stratum lucidum

NGSS.MS-LS1-2

a layer of skin that's located between the stratum basale and stratum granulosum layers of the epidermis. It's made up of several rows of keratinocytes that are held together by desmosomes, which are sticky proteins that resemble spines

NGSS.MS-LS1-3

thin layer of cells in the epidermis that's located between the stratum spinosum and the stratum corneum and gives the epidermis its water proofing ability.

NGSS.MS-LS1-2

the outermost layer of the epidermis and the first line of defense for the skin. It's made up of dead skin cells called corneocytes, which are rich in keratin, a protein also found in hair and nails.

• stratum basale

• stratum spinosum

• stratum granulosum

• stratum corneum

• stratum lucidum

a thin, translucent layer of dead skin cells in the epidermis that acts as a barrier between the living and dead layers of the skin. It's located between the stratum granulosum and the stratum corneum, and is only found in thick skin areas like the palms and soles of the feet.

• stratum spinosum

• stratum granulosum

• stratum corneum

• stratum lucidum

are the primary type of cell found in the epidermis, the outermost layer of the skin. In humans, they constitute 90% of epidermal skin cells

• keratinocyte

• melanocyte

• cornocyte

• Merkel cell

• Langerhan's cell

cells that produce melanin, a pigment that gives color to skin and hair, and protects the skin from ultraviolet radiation damage.

• Langerhan's cell

a type of skin cell that are near nerve endings and help with touch sensation.

a type of white blood cell that help the body fight infection and regulate the immune system. They are found throughout the body, especially in the skin, lymph nodes, spleen, lungs, liver, and bone marrow.
