There are three types of neurons. Neurons carry information from sense organs to the spinal cord and brain. In the brain, carry information from the sensory neurons to neurons, which causes muscles to contact and move.

The right answers are:

1. Sensory neurons

2. Interneurons.

3. Motorneurons.

The sensory neuron is located in a sensory ganglion that plays a role in the perception of a stimulus. Sensory neurons are often called afferent fibers (or neurons).

Motor neurons are neurons located in the anterior horn of the cord, innervating and controlling the muscle fibers.

The interneurons, as its name suggests, connect between two neurons.
