nervous system

Question 1

is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body

Answer 1

nervous system

Question 2

is the stimuli that is perceived by our senses like smell, sight, touch, taste, and hearing.

Answer 2

sensory input

Transmits impulses from the CNS to effector organs,

Answer 3

integration

Question 4

the complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord

Answer 4

central nervous system

Question 5

the nervous system outside the brain and spinal cord

Answer 5

peripheral nervous system

Question 6

is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles

Answer 6

somatic nervous system

Question 7

the part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes

Answer 7

autonomic nervous system

Question 8

These cells that form myelin, protect, support, and maintain equilibrium in your nervous system are called glial cells

Answer 8

neuroglia

Question 9

characteristic star-shaped glial cells in the brain and spinal cord

Answer 9

astrocytes

Question 10

they act as the first and main form of active immune defence in the central nervous system

Answer 10

microglia

Question 11

a type of glial cell

Answer 11

ependymal cells

Question 12

a glial cell similar to an astrocyte but with fewer protuberances, concerned with the production of myelin in the central nervous system

Answer 12

oligodendrocytes

Question 13

a myelin-secreting glial cell that spirally wraps around an axon of the peripheral nervous system to form the myelin sheath

Answer 13

Schwann cells

Question 14

are precursors to skeletal muscle cells, able to give rise to satellite cells or differentiated skeletal muscle cells

Answer 14

satellite cells

Question 15

Neuron is a biweekly peer-reviewed scientific journal published by Cell Press, and imprint of Elsevier

Answer 15

neurons

Question 16

a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body

Answer 16

dendrites

Question 17

the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells

Answer 17

axons

Question 18

is a specialized part of the cell body of a neuron that connects to the axon

Answer 18

axon hillock

Question 19

are separated from neighboring neurons by a small gap called a synapse, across which impulses are sent

Answer 19

axon terminals

Question 20

a fatty white substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.

Answer 20

myelin

Question 21

a gap in the myelin sheath of a nerve, between adjacent Schwann cells.

Answer 21

nodes of Ranvier

Question 22

loss of the difference in charge between the inside and outside of the plasma membrane of a muscle or nerve cell due to a change in permeability and migration of sodium ions to the interior

Answer 22

depolarization

Question 23

In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls

Answer 23

action potential

Question 24

refers to the change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential has changed the membrane potential to a positive value.

Answer 24

repolarization

Question 25

the principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, left and right, separated by a fissure

Answer 25

cerebrum

Question 26

integrates sensory information among various modalities, including spatial sense and navigation

Answer 26

parietal lobe

Question 27

is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behavior

Answer 27

frontal lobe

Question 28

is one of the four major lobes of the cerebral cortex in the brain of mammals

Answer 28

occipital lobe

Question 29

each of the paired lobes of the brain lying beneath the temples, including areas concerned with the understanding of speech.

Answer 29

temporal lobe

Question 30

the darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites

Answer 30

gray matter

Question 31

s composed of bundles, which connect various gray matter areas

Answer 31

cerebral white matter

Question 32

is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for a number of functions including motor skills such as balance, coordination, and posture

Answer 32

cerebellum
