neurons

Question 1

dendrite

Answer 1

numerous short nerve process that pick up nuerotransmitters from other nuerons and trasmit it toward cell body

Question 2

axon

Answer 2

long nerve cell process carrying impulse from cell body toward the axon terminals

Question 3

myelin sheath

Answer 3

insulating covering of axon and help facilitate impulses

Question 4

node of ranvier

Answer 4

gap in myelin sheath that helps facilitate rapid conduction of the nerve impulse down the axon

Question 5

axon terminal

Answer 5

release neurotransmitter into synaptic space to continue signal transmission

Question 6

neurotransmitter

Answer 6

chemical substance that acts synapse to stimulate or inhibit transmission of impulse

Question 7

synapse/synaptic space

Answer 7

extremely small space between neurons that neurotransmitters travel across

Question 8

nerve signals travel

Answer 8

40-60 m/sec

Question 9

action potential

Answer 9

change in electrical charge as it passes along the membrane of the axon

Question 10

action potential is how “electrical signals” travel from

Answer 10

brain to their target

Question 11

frequency and rate of action potential

Answer 11

contains the message

Question 12

reflexes

Answer 12

sensory neuron bring in stimuli

Question 13

the stimuli travels

Answer 13

to the spinal cord

Question 14

unlike normal transmission, reflex signals are not sent to the brain but the

Answer 14

spinal cord, communicates to motor neurons what needs to be done

Question 15

reflexes always

Answer 15

happen at a faster speed
