1. the integumentary system is comprised of what 3 parts of the body?: hair,
skin and nails
2. List the 3 layers of the skin from superficial to deep: Epidermis, Dermis,
Hypodermis
3. Describe 3 functions of the integumentary system: 1. Production of vitamin D
2. Contain sense organs for protection of skin and underlying tissue
3. protection from pathogens
4. True or False: Thermoreceptors detect fine touch: FALSE
Mechanoreceptors detect fine touch.
Thermoreceptors detect hot and cold
5. True or False: Merkel's cells and Meisner's corpuscles are thermoreceptors-
: FALSE
They are mechanoreceptors that detect mechanical sensory information in the form
of light touch and vibration
6. True or False: Pacinian corpuscles detect pressure: TRUE
7. Sensory organs embedded within the layers of the skin:
8. Describe what an exocrine gland contains and how its contents reach the
surface of the skin: Exocrine glands contain secretions which are released through
a duct (opening) into an epithelial surface or lining
9. What is a sebaceous gland?: Sebaceous glands (oil glands) produce sebum
(oil)
10. What is the purpose of thermoregulation in the body?: Thermoregulation
helps the body to regulate its temperature.
Perspiration is one method in assisting thermoregulation.
11. True or False: The epidermis is made up of stratified cuboidal epithelium-
: FALSE
stratified squamous epithelium
12. What are the 4 layers of the epidermis?: stratum corneum, stratum granulo-
sum, stratum spinosum, stratum basale
13. True or False: Cells of the stratum basal have a high rate of cell division: -
TRUE

14. The cells of the stratum basal have epidermal ridges which are the basis
for each person's distinct pattern called _________?: fingerprints
15. True or False: Dead cells in the stratum corneum remain for about 2 weeks
before they slough off: TRUE
16. These types of cells produce keratin: keratinocytes
17. These types of cells produce melanin: melanocytes
18. What are the 2 layers of the dermis? Which layer contains the main blood
supply for the skin?: papillary and reticular; the reticular region contains the main
blood supply
19. What is the medical term for a bruise?: contusion
20. What is one of the purposes of the hypodermis?: fat helps to insulate and
regulate body temperature
the thickness of the hypodermis protects protects the deeper tissues and organs
from injury
21. What is a dermatome?: a dermatome is a region of skin innervated by one
sensory nerve
22. Where is the information gathered from a dermatome sent?: the sensory
information gathered in each region of the skin is sent to the spinal cord and then
finally the brain for processing
23. True or False: the root of the hair follicle begins at the shaft: FALSE
The root of the hair follicle begins at the HAIR BULB
24. Each hair follicle is connected to a muscle called ____________: arrector
pili muscle
25. True or False: hair can be impacted by hormones circulating in the body: -
TRUE
26. True or False: nails are comprised of live skin cells: FALSE
nails are comprised of dead skin cells
27. Is the nail body the visible or the invisible portion of the nail?: the nail body
is the visible portion of the nail
28. What types of cells form a blood clot?: blood platelets
29. Mast cells release what type of chemical?: histamine
30. What is the purpose of the chemical released by mast cells?: helps to dilate
blood vessels to bring increased blood and nutrients to the injured area
31. True or False: Fibroblasts are involved in engulfing foreign bacteria and
particles: FALSE
