ALL COMPONENTS OF NEURONS AND NERVES

Neurons are the smallest components of the nervous system and are single nerve cells.

Axons of neurons grouped together form nerves.

Nerves connect all the muscles in the body to the brain and spinal cord.

<p>The three main parts of a neuron are dendrites, cell body, and axon.</p> Signup and view all the answers

<p>Dendrites receive chemical signals or neurotransmitters from other neurons and transmit the electrical information down the axon of the neuron.</p> Signup and view all the answers

<p>The axon carries the electrical message down its length, toward the axon terminal, and is usually covered with a thin layer of myelin sheath which helps to insulate and increase the speed of transmission.</p> Signup and view all the answers
