neurons

Question 1

sensory neurone

Answer 1

axon, myelin sheath, receptor cell

found in receptors like eyes, ears, tongue, skin
–> carry nerve impulses to spinal cord and brain
–> reflex actions

Question 2

relay neurone

Answer 2

dendrite, pre-synaptic terminal

brain and spinal cord

allow sensory and motor neurones to communicate

Question 3

motor neurone

Answer 3

control muscle movement

release neurotransmitters that bind to receptors on muscles to trigger a response

Question 4

dendrites

Answer 4

receive signals from sensory receptor cells

Question 5

axon

Answer 5

long slender fibre carrying action potential (nerve impulse) away from cell body towards axon terminals

Question 6

myelin sheath

Answer 6

insulates axon so electrical impulses travel faster

Question 7

axon terminal

Answer 7

synaptic transmission connecting neuron to other neurons
