Integumentary System
1. The integumentary system comprises three parts of the body?
Hair, skin, nails
2. List the three layers of the skin from superficial to deep.
epidermis, dermis, hypodermis
3. Functions of the integumentary system:
Production of vitamin D; contain sense organs for protection of skin and underlying tissue; protection
from pathogens
4. Thermoreceptors detect fine touch.
False, Merkel’s cells respond to light touch
5. Merkel’s cells and Meisner’s corpuscles are thermoreceptors.
False.
6. True or false: Pacinian corpuscles detect pressure.
True
Glands
8. Describe what an exocrine gland contains and how its contents reach the surface of the skin.
Exocrine glands contain secretions released through ducts into the epithelial surface. Secretions can be
released onto the surface of the skin or onto an epithelial surface, such as the salivary amylase released
into the mouth.
9. What is a sebaceous gland?
Sebaceous glands are oil glands that produce sebum, which keeps skin and hair from drying out and
impairs the growth of harmful microorganisms.
10. What is the purpose of thermoregulation in the body?
The purpose of thermoregulation in the body is to regulate the body's temperature by releasing heat, as
neccessary, through sweat glands. This is called perispiration and it occurs when sweat is released by
duct to the epidermis.
The Epidermis
11. True or false: The epidermis is made up of stratified cuboidal epithelium.
False (stratified squamous epithelium)
12. What are the four layers of the epidermis?
Stratum corneum, stratum granulosum, stratum spinosum and stratum basale
