neurons

Question 1

define neurons

Answer 1

a neuiron is a nerve cell that is the basic building block of the nervous system

Question 2

define dendrites

Answer 2

dendrites pass the messages on to the cell body, they cantain the receptors in the cell membrane

Question 3

define the cell body

Answer 3

it is the home of the nucleus and most cell organelles, it produces all protiens (neurotransmitters) for the neuron

Question 4

define axon

Answer 4

the axon carries electrical impulses away from the cell body toward the axon terminal

Question 5

deifne mylein sheath

Answer 5

the fatty coverings that protect the axon from stimuli that could intefere with transmission of impulses.

Question 6

define axon terminals

Answer 6

axon terminals recieve and store electrical impulses, where the impulses stimulate the he neurotransmitters to be released into the synaptic cleft

Question 7

define sesnroy neurons

Answer 7

sensory neirons carry stimuli from the body and from the outside world into teh central nervous system

Question 8

example of sesnroy neirons

Answer 8

when you touch a fluffy dog, the soft fur is detected by the sensory receptors in the skin and sent to the brain via sensory neurons

Question 9

define motor neurons

Answer 9

communitcate messages from the cns to the muscles that an organisms intend to move to at any point in time

Question 10

example of motor neurons

Answer 10

when yout touch a fluffy dog yoour motor enurons are responsible for moving your arm

Question 11
