neuron structure and function

Question 1

dendrites

Answer 1

neutron cell processes that extend from the cell body and direct stimulus towards the cell body

Question 2

axon

Answer 2

long cell process that extends from the neutron cell body. directs stimulus towards the synapse, away from the cell body.

Question 3

axon hillock

Answer 3

beginning of the axon which lies close to the neutron cell body

Question 4

axon end bulb

Answer 4

site of neurotransmitter release where the synaptic vesicles reach the pre-synaptic membrane.

Question 5

synapse

Answer 5

specialised intercellular gap between the axon end bulb and target cell and between neutron cells

Question 6

what is the role of the microtubules within the axon of a neuron?

Answer 6

The microtubules move the synaptic vesicles down the axon. Mitochondria provide the energy to do this

Question 7

how are the synaptic vesicles released at the synaptic end bulb?

Answer 7

exocytosis

Question 8

What is the Node of Ranvier?

Answer 8

the gap between the internodes of the axon where the signals jump over.
