Structures and Functions of Neurons

Question 1

What is the function of sensory neurons? Where are they found?

Answer 1

They carry impulses from receptors to relay neurons

Found in receptors such as the eyes, ears, tongue and skin

Question 2

How are sensory neurons structured?

Answer 2

Receptor cell > Myelinated axon > Cell body > Axon terminals

Question 3

What is the function of relay neurons? Where are they found?

Answer 3

To carry signals from sensory neurons to motor neurons

Found in the brain and spinal cord

Question 4

How are relay neurons structured?

Answer 4

Dendrite > Cell body > Non-myelinated axon > Pre synaptic axon terminal

Question 5

What is the function of motor neurons? Where are they found?

Answer 5

To control muscle movements by recieving the signals produced to activate effector muscles

Found in the CNS

Question 6

How are motor neurons structured?

Answer 6

Dendrite > Cell body > Myelinated axon > Node of ranvier > Effector cell
