Neurons

Question 1

dendrites

Answer 1

receive nerve impulses (action potentials) from other neurons + send to cell body

Question 2

axons

Answer 2

takes signal away from cell body to axon terminal

Question 3

cell body

Answer 3

contains nucleus, cite of metabolic reactions

Question 4

sensory neurons

Answer 4

receive impulses from sensory receptors+ send to interneurons

Question 5

interneuron

Answer 5

enable communication bte sensory/motor neurons to cns

Question 6

motor neurons

Answer 6

send nerve impulses away from cns to effectors (muscles)

Question 7

glial cells

Answer 7

nourish neurons, remove waste, defend against infection

Question 8

schwann cells

Answer 8

form myelin sheath that insulates axons + increases speed of transmission

Question 9

Nodes of Ranvier

Answer 9

gap btw axons that impulses jump across to increase speed of transmission

Question 10

axon terminals

Answer 10

produce neurotransmitters that send signals to other cells

Question 11

reflex arc

Answer 11

motor pathways with few neurons that allow for involuntary rapid response

recceptor-sensory neurons-interneauron - motor neuron- effector

Question 12

Action potential

Answer 12

nevre impulse
