Integumentary System

Question 1

What organs does the Integumentary system?

Answer 1

Skin, hair, nails, sebaceous gland, sudoriferous glands, ceruminous glands, hair follicles, apocrine sweat glands, and eccrine sweat glands

Question 2

What are the different skin layers?

Answer 2

Epidermis, Dermis, Hypodermis/subcutaneous layer

Question 3

What is the epidermis (on the OUTSIDE) made up of?

Answer 3

dead cells

Question 4

What kind of cells produce and distribute melanin?

Answer 4

Melanocytes

Question 5

What is the inside of the epidermis made up of?

Answer 5

Inner layer of cells

Question 6

What does the dermis contain?

Answer 6

collagen, blood vessels, glands, hair follicles, and nerve endings

Question 6

What are the functions of the integumentary system?

Answer 6

Protection, Excretion, and interaction with the environment

Question 6

How does the integumentary system protect the body?

Answer 6

Provides barrier between the body and outside pathogens, Prevents body from drying out, Divides quickly, pushing older cells towards the surface (Create a tough, waterproof outer surface), Melanocytes in the epidermis produce melanin (protects the body from ultraviolet radiation

Question 7

How does excretion work?

Answer 7

Water, minerals (sodium chloride, magnesium) are excreted by glands

Question 8

How does the integumentary system interact with the environment?

Answer 8

Contains sensory nerve endings that allow the body to detect: Touch, Change in temperature, pain. Skin also produces vitamin D when UV lights hit the skin

Question 9

Example of homeostasis in the integumentary system is

Answer 9

Body temperature– too hot, produces sweat (blood vessels dilate). too cold, blood vessels constrict, less blood is carried to the skin surface

Question 10

Integumentary system

Answer 10

An organ system comprised of skin and its associated organs

Question 11

Excretion

Answer 11

Elimination of metabolic waste from the body

Question 12

Homeostasis

Answer 12

The maintenance of a constant internal environment

Question 13

Sebaceous Glands

Answer 13

Accessory structures originating in the dermis that secrete sebum onto hair emerging from the hair follicle

Question 14

Ceruminous glands

Answer 14

Accessory structures that produce ear wax. They are found only in the dermis of the ear canal

Question 15

Hair follicles

Answer 15

Tubes arising from the dermis surrounded by invaginations of epithelial tissue, from which hair growth occurs

Question 16

Apocrine Sweat gland

Answer 16

Accessory structures of the dermis that are in physical association with hair follicles, producing a secretion with an odor (possibly a sex pheromone to humans)

Question 17

Eccrine Sweat glands

Answer 17

Accessory structures originating throughout the dermis of the human body that secrete sweat, used primarily for regulation of body temperature

Question 18

Epidermis

Answer 18

The outer layer of the skin

Question 19

Dermis

Answer 19

The middle layer of skin

Question 20

Subcutaneous

Answer 20

Under the dermis

Question 21

Hypodermis

Answer 21

The deepest layer of the skin

Question 22

Vitamin D

Answer 22

A vitamin made by the skin that helps the intestine absorb dietary calcium

Question 23

Cutaneous Vasoconstriction

Answer 23

A decrease in the diameter of blood vessels in the dermis that reduces blood flow through the skin
