Question 1

Motor neuron function and length of fibres

Answer 1

• form synapses with muscles and control their contractions
• function is to carry messages from the CNS to effectors such as muscles or glands
• short dendrites and long axons

Question 2

relay neuron function and length of fibres

Answer 2

• most common in CNS and allow sensory and motor to communicate
• function is to transfer messages from sensory neurons to other interconnecting and motor neurons
• short dendrites and short or long axons

Question 3

sensory neuron function and length of fibres

Answer 3

• Carry nerve impulses from sensory receptors to spinal cord and brain
