CORRECT Answers
, function the skin 1. Protects tissue and organs,
2. Regulates/Excrete salts, water, and organic wastes,
3. Maintain body temperature
4. Produces melanin and keratin
6. Makes vitamin D3
7. Stores lipids
8. Immunity (Body's first line of defense against environment)
List the three layers of skin (Superficial to Deep!) Epidermis, Dermis, and Subcutaneous layer (hypodermis)
Epidermis made up of stratified squamous epithelial tissue. Holds Melanocytes and
Keratinocytes.
Dermis Holds everything else not in the Epidermis and Subcutaneous: hair follicle, blood
vessels, nails, sweat glands, nerve receptors, and oil glands(Sebaceous).
Subcutaneous layer (hypodermis) Contains adipocytes that make adipose tissue
List the layers of the epidermis in order. (Superficial to Stratum Corneum
Deep) Stratum Lucidum (THICK SKIN ONLY)
Stratum Granulosum
Stratum Spinosum
Stratum Basale
Melanin a brown, yellow-brown, or black pigment that functions in skin, eye, & hair color
and protects against UV radiation.
Melanocytes cells that produce Melanin
Keratinocytes cells that produce Keratin
Keratin provides skin toughness & acts as a water repellant
Carotene produces an orange-yellow pigment
thick skin Found on palms of hands and soles of feet and contains five strata (layers)
thin skin Covers most of body surface and contains four strata (layers). Does NOT contain
stratum lucidum.
1st Degree burn Impacts the 1st layer of skin, the epidermis. Results in redness (Erythema) and pain.
2nd Degree burn Impacts 1st & 2nd layer of skin, the epidermis and Dermis. Results in redness
(Erythema), pain, and blisters.
3rd Degree burn Impacts all layers, the epidermis, dermis, and hypodermis. Results in less pain and
cannot repair itself. Needs skin grafts.
