This deepest epidermal layer contains actively dividing cells and melanocytes.

What is the Stratum Basale? 

100

A papercut does not bleed or cause much pain. This layer of the integument is the only layer effected. 

What is the Epidermis?

100

The living part of the nail, under the nail plate.

What is the Nail bed?

100

This structure sticks up/out from the most superficial layer of the skin. 

What is a hair/hair shaft?

100

This medical specialty focuses on the diagnosis, study, and treatment of skin disorders

What is dermatology?

200

This layer of the skin lies beneath the epidermis and contains blood vessels, nerves, glands, and hair follicles

What is the dermis?

200

This is the process by which a wound heals by scar formation rather than complete replacement of original tissue

What is fibrosis?

200

A patient exposed to cold temperatures develops decreased blood flow to the skin. This is the process where blood vessels get smaller to decrease surface area and their skin turns blue

What is vasoconstriction? 

200

This small smooth muscle attached to a hair follicle causes hair to stand up, producing “goosebumps.”

What is the arrector pili?

200

The skin is also known as the __________ membrane.

What is the Cutaneous membrane.

300

A patient’s skin appears darker after UV exposure, but the number of melanocytes has not significantly increased. This cellular product is mainly responsible for the darker appearance.

What is Melanin?

300

This is the first stage of wound healing where blood fills the wound and starts to clot. 

What is Hemostasis?

300

A nail rips and the skin, aka ____________, underneath the free edge is ripped.

What is the Hyponychium 

300

These sweat glands are the most common type and help regulate body temperature. (specifically!)

What are merocrine sweat glands?

300

This blood pigment can give skin a reddish color depending on blood flow and oxygenation.

What is hemoglobin?

400

This cell that makes up most of the epidermis and produces keratin to help form our most superficial barrier. 

What are keratinocytes?

A patient has a chronic inflammatory skin condition involving excessive keratinocyte production, leading to thickened, scaly lesions. This disease is caused by the immune system attacking the skin.

What is psoriasis?

400

These modified sweat glands produce earwax.

What are ceruminous glands

400

This sensory receptor is often shown deep in the dermis or hypodermis and detects deep pressure

What is a lamellar corpuscle?

400

A chemotherapy patient experiences diffuse hair loss because rapidly dividing cells are affected. This phase of active hair growth is heavily affected. 

What is the Anagen Phase? 

500

These bundles are formed by the orientation of collagen and elastin bundles and are important in surgery to reduce scarring

What are lines of cleavage?

500

This is the reason a third-degree burn can be life-threatening even if the patient reports little pain at the deepest part of the burn.

What is risk of dehydration/fluid loss? OR What is loss of the protection against pathogens/germs?

500

These glands in a patient’s axillary and pubic become more active at puberty and produce a secretion associated with body odor. (Be specific)

What are apocrine sweat glands?

500

On a skin model, this sensory receptor is located in the papillary dermis and is associated with light touch.

What is a tactile corpuscle? 

500

A patient has low calcium levels. This  integumentary-related compound is involved in helping increase calcium absorption from the digestive tract. (BOTH NAMES)

What is Active Vitamin D? AND What is Calcitriol?
