Structure and Function of Sensory, Relay and Motor neurons

Question 1

Sensory Neuron location

Answer 1

The PNS in clusters known as ganglia

Question 2

Sensory Neuron function

Answer 2

Send info from the senses (PNS) towards the brain (CNS)

Question 3

Sensory Neuron structure

Answer 3

Long dendrites and short axons
Cell body in the middle

Question 4

Relay Neuron location

Answer 4

Found in the CNS (brain/spinal cord)

Question 5

Relay Neuron function

Answer 5

Carry nerve impulses between neurons allowing sensory and motor neurons to communicate
Involved in analysing the sensations from these neurons and deciding how to respond

Question 6

Relay Neuron structure

Answer 6

Short dendrites and short axons, no myelin sheath

Question 7

Motor Neuron location

Answer 7

Cell bodies are found in the CNS but the long axons form part of PNS

Question 8

Motor Neuron function

Answer 8

Send info via long axons from the brain/spinal cord (CNS) through to effectors such as muscles or glands

Question 9

Motor Neuron structure

Answer 9

Short dendrites and long axons
