24
Q

Give an example of an effector

A

Muscle or glands

25
This sends a nerve impulse through the neuron.
The axon
26
This part of the neuron contains the genetic material of the cell.
Cell body
27
This part of the neuron protects the axon.
Myelin sheath
28
The gaps between the neurons are called ...
the nodes of ranvier
29
This part of the neuron is the end of the neuron.
Terminal button
30
Is the signal within the neuron: electrical or chemical
Electrical
31
When information crosses from the pre to the post synaptic neuron, is it electrical or chemical.
Chemical
32
What is another name for a nerve impulse?
Action Potential
33
A motor neuron is located in the PNS in clusters known as ganglia - TRUE or FALSE.
False - this is the location of a Sensory neuron
34
A relay neuron is found in the brain/spinal cord/visual system - TRUE or FALSE?
True
35
Sensory neurons send information via long axons from the brain/spinal cord through to effectors like muscles or glands - TRUE or FALSE.
False - This is the function of a motor neuron.
36
How would we visually identify the difference between a sensory and a motor neuron?
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).
37
How would we visually identify the difference between a relay and a motor neuron?
Relay neurons have no myelin sheath whereas motor neurons have myelin sheath
