Answer 30

Electrical

Question 31

When information crosses from the pre to the post synaptic neuron, is it electrical or chemical.

Answer 31

Chemical

Question 32

What is another name for a nerve impulse?

Answer 32

Action Potential

Question 33

A motor neuron is located in the PNS in clusters known as ganglia - TRUE or FALSE.

Answer 33

False - this is the location of a Sensory neuron

Question 34

A relay neuron is found in the brain/spinal cord/visual system - TRUE or FALSE?

Answer 34

True

Question 35

Sensory neurons send information via long axons from the brain/spinal cord through to effectors like muscles or glands - TRUE or FALSE.

Answer 35

False - This is the function of a motor neuron.

Question 36

How would we visually identify the difference between a sensory and a motor neuron?

Answer 36

A sensory neuron has long dendrites and short axons, whereas a motor neuron has short dendrites and long axons. Also, a sensory neuron’s cell body is located in the middle of the axon, whilst a motor neuron’s cell body is located at the top (close the the dendrites).

Question 37

How would we visually identify the difference between a relay and a motor neuron?

Answer 37

Relay neurons have no myelin sheath whereas motor neurons have myelin sheath
