Structure and function of neurons and synaptic transmission
- 4 things to know
- Paper 2
Overview
Sensory, relay and motor neurons, the effect of myelination on conduction speed, and the sequence of chemical transmission at a synapse, including excitatory and inhibitory neurotransmitters.
What you need to know
Answer each one before you reveal it.
Your recallNot started
Process
Why does a myelinated axon conduct impulses faster?
Process
Outline the sequence of chemical transmission at a synapse.
Key term
How do the two kinds of neurotransmitter differ in their effect?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is the function of sensory neurons?
Model answer
Sensory neurons transmit nerve impulses from receptors to the central nervous system.
- 2
What role do relay neurons play in neural communication?
Model answer
Relay neurons transmit nerve impulses between sensory neurons and motor neurons within the central nervous system.
- 3
Where do motor neurons transmit nerve impulses to, and what structures do they target?
Model answer
Motor neurons transmit nerve impulses from the central nervous system to effectors such as muscles and glands.
- 4
Describe the relative lengths of the dendrite and axon in a sensory neuron.
Model answer
Sensory neurons have a long dendrite and a short axon.
- 5
Where is the cell body positioned in a sensory neuron?
Model answer
The cell body is located in the middle of the neuron along the dendrite.
- 6
What are the relative lengths of the dendrite and axon in a relay neuron?
Model answer
Relay neurons have a short dendrite and a short axon.
