Answer:

Sensory neurons transmit messages within the brain the neurons transfer messages between neurons.

Explanation:

The received messages in human nervous system travels within the brain as well as to other body parts as electrical impulses by the neuron.  The billions of sensory neurons work in the brain. The major three parts of the neuron is the cell body, axon and myelin sheath that work together in transmitting messages.

The cell body extends dendrite and receives messages from cells of the nerves which later are transmitted from the cell body to the other neuron dendrites or other tissues by the axon. The cover of neurons, the myelin sheath accelerates the transmitting of signals.
