How do neurons travel through the body

Sensory neurons are neurons that let us feel sensation.Motor neurons are responsible for voluntary control of the muscles all over the body.Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles.The signals from your cut hand travel into the spinal cord through the dorsal roots.The thicker the axon, the more rapidly the signal is sent.

When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters.However, nearly all neurons have three essential parts:Each neuron in your brain has one long cable that snakes away from the main part of the cell.Sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle.The electrical signal, or action potential, runs from the cell body area to the axon terminals, through a thin fiber called axon.

They synapse on neurons within the spinal cord segment that they entered and also on neurons one to two segments above and.Transmitting information throughout the body.Afferent neurons are also known as sensory neurons, and they transmit the signals that we receive from our senses, including our ability to touch, hear, see, smell, and taste.Cell body, dendrites, and axon.This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.

Then it crosses a space about a millionth of an inch wide.Depending on the job of the fiber, the speed can change a lot.
