Control and Coordination

Nerves are of three types based on the types of neurons they carry. They are:

Sensory Nerves or the Receptor Nerves

They are made up of only sensory neurons. For example, the cranial nerves that conduct impulses from the organs to the central nervous system.

Motor Nerves or the Effector Nerves

They are made up of only motor neurons. For example, the cranial nerves that conduct impulses from the central nervous system to the muscles and glands (effector).

Mixed Nerves

The nerves that are made up of both sensory and motor neurons. For example, all spinal nerves.
