Intro to the nervous system

Question 1

The part of the nervous system that carries signals from your CNS to only your skeletal muscles.

Answer 1

Somatic or Voluntary Nervous system

Question 2

In the nervous tissue, the type of cell that can transmit signals from one another?

Answer 2

Neuron

Question 3

The part of the peripheral nervous system that carries signals from your central nervous system to your muscles and glands.

Answer 3

Motor or efferent division

Question 4

What produces and insulating barrier called myelin sheath in the central nervous system?

Answer 4

Oligodendrocyte

Question 5

What is the main source of immune defense against invading microorganisms?

Answer 5

microglial cells

Question 6

What is it called when the central nervous system processes an input and decides what should be done with it?

Answer 6

Integration

Question 7

In nervous tissue, the type of cell that can transmit signals from one cell to another.

Answer 7

Neuron

Question 8

What is the signal the CNS sends out to activate certain parts of the body?

Answer 8

Motor output

Question 9

The part of the nervous system consisting of the brain and spinal cord.

Answer 9

CNS

Question 10

In the CNS, these transmit impulses between other neurons.

Answer 10

interneurons

Question 11

A neuron with one axon and a single dendrite extending from its soma, found in limited places like the retina of the eye.

Answer 11

Bipolar neuron

Question 12

Most abundant and versatile glial cells. They govern the exchange of materials between neurons and capillaries.

Answer 12

Astrocytes

Question 13

All the nerves branch off from the brain and spine and allow your CNS to communicate with the rest of your body.

Answer 13

Peripheral Nervous System

Question 14

Branch-like processes that pick up messages from other cells.

Answer 14

Dendrites

Question 15

Surround and support neuron cell bodies.

Answer 15

Satellite cells

Question 16

Create, secrete and circulate cerebrospinal fluid.

Answer 16

ependymal cells

Question 17

Produce insulating barrier called myelin sheath in the peripheral nervous system

Answer 17

Schwann cells

Question 18

In the peripheral nervous system, these receive messages from the central nervous system and transmit impulses out to peripheral effector organs, like muscles and glands.

Answer 18

efferent neurons

Question 19

In the peripheral nervous system, these pick up messages from sensory receptors and transmit impulses toward the CNS.

Answer 19

Afferent neurons

Question 20

A neuron with a simple extension from the soma that leads to an axon with dendrites at one end and axon terminal sat the other; peripheral sensory neurons are this type.

Answer 20

unipolar neurons

Question 21

The first function of the nervous system, describes the reception of stimuli by our senses and transmission of the signal to the central nervous system.

Answer 21

sensory input

Question 22

Part of the nervous system that carries signals from your central nervous system to regulate things like your heart beating, lungs breathing, and stomach churning.

Answer 22

Autonomic nervous system

Question 23

The part of the autonomic nervous system that encourages digestion, relaxes the body, and store excess energy

Answer 23

Parasympathetic division

Question 24

In the peripheral nervous system, these receive messages from the central nervous system and transmit impulses out to peripheral effector organs, like muscles and glands,

Answer 24

efferent neurons

Question 25

The part of the autonomic nervous system that mobilizes energy and gets the body ready to fight or flee

Answer 25

sympathetic system

Question 26

The most common type of neuron in the body

Answer 26

multipolar neuron

Question 27

Produce insulting barrier called myelin sheath in the peripheral nervous system

Answer 27

schwann cells

Question 28

All the nerves that branch off the brain and spine and allow your central nervous system to communicate with the rest of your body.

Answer 28

Peripheral nervous system

Question 29

Long extension or fiber that transmits electrical impulses away from the cell body to other cells.

Answer 29

Axon
