What is an intermediate neuron?

An intermediate neuron is a neuron that is interposed between the sensory neuron and the motor neuron in a reflex arc. Intermediate neurons are also known as internuncial neurons or interneurons. They are located in the central nervous system, specifically in the spinal cord and the brain.

Intermediate neurons receive signals from sensory neurons and then send signals to motor neurons. This allows for the integration of sensory information and the generation of a motor response. For example, when you touch a hot object, the sensory neurons in your skin send signals to the intermediate neurons in your spinal cord. The intermediate neurons then send signals to the motor neurons in your muscles, which causes you to withdraw your hand from the hot object.

Intermediate neurons are essential for the proper functioning of the nervous system. They allow for the rapid and efficient transmission of information between sensory and motor neurons, which is necessary for reflexes and other rapid responses to environmental stimuli.
