A cell that connects sensory and motor pathways for reflexes.
sensory,internueron and motor are the names.The nervous system has three basic functions:sensory neurons receive information from the sensory receptorsinterneurons transfer and interpret impulses.motor neurons send appropriate impulses/instructions to the muscles and glands.
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.
