Integumentary System Study Guide Answer
Integumentary System Study Guide
1. Which portion of the epidermis has actively reproducing cells? Stratum Basale
2. Are keratin levels higher in superficial or deep epidermis? Superficial
3. Blood vessels and nerves are present in which layer of skin? Dermis
4. In what layer of skin can you find melanocytes? Epidermis (stratum basale)
5. What structure pulls the hair follicle into an upright position? Arrector Pili
6. What structure is responsible for whorled ridges on epidermal surfaces? Dermal Papillae
7. What region of the integumentary system is responsible for shock absorption? Hypodermis
8. Which skin gland produces sweat? Sudoriferous - Eccrine
9. Which skin gland produces oil/sebum? Sebaceous
10. In a hair, the outermost single layer of cells that overlap one another like shingles is called
11. the cuticle.
12. The part of a hair that projects from the surface of the scalp or skin is called the hair shaft. 13. The skin that covers the palms of the hands and the soles of the feet has an extra layer of epidermis called the stratum lucidum.
14. The type of burn that involves injury to the epidermis and the upper region of the dermis and is red, blistered, and painful is termed as a second degree burn.
15. The white crescent area located over the nail matrix is called the lunula.
16. Baldness is medically termed alopecia.
17. The most external skin region is composed of squamous epithelia.
18. What are the types of epithelial tissue membranes? Cutaneous (skin), mucous, serous
19. What is the first threat to life from a massive third-degree burn? Dessication
20.Where are mucous membranes located in the body? Line cavities open to the outside
21. How is the "tanning" effect (darkening of the skin) that occurs when a person is exposed to the sun somewhat protective? Exposure to UV radiation causes melanocytes to increase melanin production. Melanin covers the nuclei of cells and absorbs UV radiation.
22.When a person has severe burns, what are the two most
1. Which portion of the epidermis has actively reproducing cells? Stratum Basale
2. Are keratin levels higher in superficial or deep epidermis? Superficial
