sensory, relay, motor neurons

Question 1

together term

Answer 1

reflex arc

Question 2

sensory neurone

Answer 2

function- detect sensations eg: pain at sensory receptors

Question 3

what happens when sensory neurone detects sensation

Answer 3

an action potential then travels across nerve passing along the myelinated axon then, an electrical signal is converted into a chemical signal to cross the synapse

Question 4

relay neurone

Answer 4

function: after synaptic transmission a new action potential forms in the dendrites this neurone is in the spine and sends signals to the cns and along its axon to the motor neurone

Question 5

motor neurone

Answer 5

function: detect signal from relay neurone via synaptic transmission and passes the signal along its own myelinated axon to stimulate an effector
(eg: muscle group in arm moving it away from pain source)

Question 6

sensory structure

Answer 6

long dendrite
short axon
cell body off to the side

Question 7

relay structure

Answer 7

short dendrites
short axon
in the cns

Question 8

motor structure

Answer 8

short dendrites
long axon
cell body at one end
