Systems of the Body - Tissue Types, Nervous System, and Integumentary System

Question 1

What is the system of the body that controls, commands, and communicates?

Answer 1

the nervous system

Question 2

What is the system of the body that generates motion?

Answer 2

the muscular system

Question 3

What is the system of the body that covers and protects?

Answer 3

the integumentary system

Question 4

What is the system of the body that supports and structures?

Answer 4

the skeletal system

Question 5

What is the system of the body that shuttles essential gases and nutrients around the body?

Answer 5

the circulatory system

Question 6

What are the two basic components of the nervous system?

Answer 6

neurons and glial cells

Question 7

What is the difference between the function of neuron and the function of a glial cell?

Answer 7

Neurons are responsible for sending and receiving signals; glial cells support the neurons

Question 8

What are the first two levels of the nervous system?

Answer 8

The central nervous system (CNS) and the peripheral nervous system (PNS)

Question 9

What parts of the body are included in the central nervous system?

Answer 9

The brain and spinal cord; the PNS is everything else.

Question 10

What are the next two levels of the peripheral nervous system?

Answer 10

The sensory division and motor divison

Question 11

What the next two levels of the motor division?

Answer 11

The somatic and the autonomic systems

Question 12

What type of action does the somatic system control?

Answer 12

voluntary action (action you choose to take)

Question 13

What type of action does the autonomic system control?

Answer 13

involuntary action (things that happen on their own; heartbeat, breathing, etc)

Question 14

Action potentials are how the nervous system communicates. What causes an action potential?

Answer 14

The movement of ions in and out of a neuron’s axon

Question 15

At rest, the axon of a neuron is _____________ charged.

Answer 15

negatively

Question 16

When a stimulus alters the shape of the cell, what kind of gated channel allows a small amount of positive ions into the axon?

Answer 16

mechanically-gated channel

Question 17

When the balance of electric potential starts to change, what kind of gated channel opens and rapidly floods the axon with positive ions?

Answer 17

voltage-gated channel

Question 18

What is it called when positive ions completely alter the charge in the axon?

Answer 18

depolarization

Question 19

What process of recharging the axon with negative ions must occur in order to send another action potential?

Answer 19

repolarization

Question 20

All action potentials are the same, so how does the brain tell the difference between one sensation and another?

Answer 20

the frequency of action potentials (how many action potentials happen in a set amount of time)

Question 21

A strong stimulus will have a ________ frequency

Answer 21

high (more action potentials)

Question 22

A weak stimulus will have a ________ frequency

Answer 22

low (fewer action potentials

Question 23

The system of skin and other external protective mechanisms is called the ____________ system.

Answer 23

integumentary system

Question 24

Skin is a blend of which two types of tissue?

Answer 24

epithelial and connective

Question 25

Which layer of the skin is made of 3-4 layers of dead epithelial tissue?

Answer 25

the epidermis

Question 26

What layer of the skin contains mostly connective tissue in the form of fat?

Answer 26

The hypodermis/subcutis

Question 27

What are the layers of the epidermis?

Answer 27

Corneum, Lucidum, Granulosum, Spinosum, Basale (Come, Let’s Get Sun Burned!)

Question 28

Which layer of the epidermis is only found in the thick skin of the palms and soles of the feet?

Answer 28

the lucidum

Question 29

What layer of the skin is a blend of connective tissue and epithelial tissue and contains the blood vessels and nerves?

Answer 29

the dermis

Question 30

If you cut skin deep enough to bleed, you’ve at least reached the ___________

Answer 30

dermis

Question 31

Where will you find the melanocytes that determine skin color?

Answer 31

the epidermis

Question 32

Besides protecting the body with skin, the integumentary system is responsible for what tasks?

Answer 32

producing essentials hormones and other materials that function with the skin, like sweat, saliva, and mucus
