ANATOMY

Detailed explanation-1: -Interneurons (also known as association neurons) are neurons that are found exclusively in the central nervous system. ie Found in the brain and spinal cord and not in the peripheral segments of the nervous system.

Detailed explanation-2: -There are approximately 20 billion interneurons, or association neurons. Most are found in the brain and the spinal cord, and others are within the autonomic ganglia. Interneurons make up > 99% of all the neurons in the body. The primary function of interneurons is integration.

Detailed explanation-3: -There are three classes of neurons: Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Motor neurons control voluntary muscle activity such as speaking and carry messages from nerve cells in the brain to the muscles. All the other neurons are called interneurons.

Detailed explanation-4: -As the name suggests, interneurons are the ones in between-they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity. They are multipolar, just like motor neurons.

Detailed explanation-5: -An interneuron (also called relay neuron, association neuron, connector neuron or local circuit neuron) is one of the three classifications of neurons found in the human body. Interneurons create neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS).
