Neurons provide the connection between the brain and the body
Explanation:
Niels is trying to imagine what the human nervous system looks like. He knows that the body has neurons that run up and down the spine and branch throughout the body. And these neurons provide the connection between the brain and the body.
Neurons are nerve cells, they constitute the building block of the nervous system, they transmit information to other nerve cells, muscle, or gland cells and provide the connection between the brain and body. Impulses/stimuli are transmitted to the brain for interpretation via the aid of neurons.
