1 Answer

Answer :

The Peripheral Nervous System consists of all the sensory nerves and the motor nerves (these carry messages to other parts of the body from the brain and spinal cord). Sensory nerves contain sensory neurons. Motor nerves contain motor neurons. Mixed nerves contain both sensory and motor neurons. Sensory neurons are usually connected to motor neurons by intermediate neurons (sometimes called inter neurons). Sensory, intermediate and motor nerves have gaps between them called synapses
