Sensory neuron
What type of neurons does this diagram show?
Relay neuron
What type of neurons does this diagram show?
Motor neuron
What is the role of a sensory neuron?
-carry nerve impulses from sensory receptors to the spinal cord and brain. From PNS to the CNS
What is the role of a relay neuron?
-allow sensory and motor neurons to communicate with each other. They are the most common type of neuron in the CNS.
What is the role of the motor neurons?
Carry nerve impulses from the spinal cord cord and brain to the effectors ( muscles and glands ). From the CNS to the PNS
