What is the epidermis?
These structures produce hair and are embedded in the dermis.
What are hair follicles?
This is the skin’s primary role in protecting internal organs from injury and infection.
What is protection?
These cells produce keratin.
What are keratinocytes?
This occurs when melanocytes produce excess melanin after sun exposure.
What is tanning?
This layer contains blood vessels, hair follicles, and sweat glands.
What is the dermis?
These glands produce oil to lubricate the skin and hair.
What are sebaceous glands?
The skin helps maintain body temperature through sweating and this process involving blood vessels.

These glands help regulate body temperature through sweating.
What are sweat (sudoriferous) glands?

What is Vitamin D?
These immune cells help defend against pathogens in the epidermis.
What are Langerhans cells?
This type of burn affects only the epidermis.
What is a first-degree burn?
This specific layer of the epidermis is responsible for continuous cell division.
What is the stratum basale?
These tiny muscles attached to hair follicles cause “goosebumps.”
What are arrector pili muscles?
This function allows us to feel pain, pressure, heat, and cold
What is sensation?
These cells are responsible for light-touch sensation in the epidermis.
What are Merkel cells?
This dangerous skin cancer arises from melanocytes.
What is melanoma?
This epidermal layer is present only in thick skin like the palms and soles.
What is the stratum lucidum?
This tough protein gives strength to hair and nails.
What is keratin?
This function involves the removal of small amounts of metabolic waste through sweat.
What is excretion?
This pigment protects deeper skin layers from UV radiation.
What is melanin?
This condition occurs when there is a lack of melanin production.
What is albinism?
