❏ Fibers Start at the Brain ❏ Muscles are controlled by neurons ❏ Signals are sent through fibers called axons ❏ Senses, such as sound and touch, send signals to the brain which are processed. ❏ This is how you perceive things. Function
❏ Axons are support by glial cells ❏ Glial cells insulate the axons so that information is relayed to the brain faster ❏ The branch of medicine that studies the nervous system is neurology ❏ Autonomic nervous system is involuntary nerves, such as heart and digestion. Facts
