Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The nerve cell that connects sensory and motor neurons is a ____
A
Motor Neuron
B
Sensory Neuron
C
Interneurons
D
Glial cells
Explanation: 

Detailed explanation-1: -Interneurons. 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.

Detailed explanation-2: -Interneurons are situated between sensory and motor neurons. 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.

Detailed explanation-3: -Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons.

Detailed explanation-4: -The nerve cells of the central nervous system are all interneurons. In human brain, there are about 100 billion interneurons. Example is the Golgi cell found in the cerebellum. The interneurons receive impulses from the sensory neurons.
