Biopsychology - Structure and Functions of Sensory, Relay and Motor Neurons Flashcards
1
Q
Where is the location of the Sensory Neuron?
A
The PNS in clusters known as ganglia
2
Q
What is the function of the Sensory Neuron?
A
- Sends information from the senses towards the brain
- Receptors can be found in eyes, ears, tongue and skin
3
Q
What is the structure of the Sensory Neuron?
A
- Long dendrites
- Short axons
4
Q
Where is the location of the Relay Neuron?
A
In the brain and the visual system
5
Q
What is the function of the Relay Neuron?
A
- Carry nerve impulses between neurons, allows sensory and motor neurons to communicate
- Involved in analysing the sensations from these neurons and deciding how to respond
6
Q
What is the structure of the Relay Neuron?
A
- Short dendrites
- Short axons
- No myelin sheath
7
Q
Where is the location of the Motor Neuron?
A
- Cell bodies are in the CNS
- Long axons form part of the PNS
8
Q
What is the function of the Motor Neuron?
A
- Send information via long axons from the brain/spinal cord through to effectors such as muscles or glands
9
Q
What is the structure of the Motor Neuron?
A
- Short dendrites
- Long axons
