Nervous System

Question 1

It is a system of cells, tissues, and organs that regulates the body’s responses by transmitting signals from one part to another.

Answer 1

Nervous System

Answer 4

Brain

Question 5

Three main parts of brain

Answer 5

Cerebrum
Cerebellum
Brain Stem

Question 6

large, upper part of the brain that controls activity and thought

Answer 6

Cerebrum

Question 7

the part under the cerebrum that controls the posture, balance and coordination

Answer 7

Cerebellum

Question 8

the part that connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate, and blood pressure

Answer 8

Brain Stem

Question 9

This serves as a channel for signals between the brain and the rest of the body and controls simple musculoskeletal reflexes without input from the brain.

Answer 9

Spinal Cord

Question 10

connects the central nervous system to the organs and limbs.

Answer 10

Peripheral Nervous System (PNS)

Question 11

this system is associated with the voluntary control of the body movements and has two main parts.

Answer 11

Somatic Nervous System

Question 12

2 parts of Somatic nervous system

Answer 12

Spinal Nerves and Cranial Nerves

Question 13

the nerves that carry motor and and sensory signals between the spinal cord and the body.

Answer 13

Spinal Nerves

Question 14

the nerve fibers that carry information into and out of the brain stem.

Answer 14

Cranial Nerves

Question 15

this system is associated with the involuntary control of body and has two subdivisions.

Answer 15

Autonomic Nervous System

Question 16

the two subdivisions of the Autonomic Nervous System

Answer 16

Sympathetic and Parasympathetic

Question 17

it is achieved when body is in a dynamic role or stress.

Answer 17

Sympathetic

Question 18

it maintains body functions and restores the body to normal or relaxed mode.

Answer 18

Parasympathetic

Question 19

the basic unit of the nervous system, has a cell body containing the nucleus, are cells with the special ability to carry signals or impulses.

Answer 19

Neurons

Nucleus

Question 22

spherical part of the neuron that contain the nucleus.

Answer 22

Cell Body

Question 23

carry the impulses toward the cell body.

Answer 23

Dendrites

Question 24

carry the impulses away from the cell body.

Answer 24

Axon

Question 25

are gaps in the myelin sheath coating in the neutral axon

Answer 25

Nodes of Ranvier

Question 26

an insulating layer, that form around the nerves and allows electrical impulses to transmit quickly and efficiently along the nerve cells

Answer 26

Myelin Sheath

Question 27

support nerve regeneration

Answer 27

Schwann Cells

Question 28

is a combination of electrical charge and a chemical reaction. It is not a flow of electricity, but an electrochemical signal moving along a neuron.

Answer 28

Nerve Impulse
