the brain and spinal cord
Central nervous system
nerves branching beyond the spinal cord into the body
Peripheral Nervous System
Messages travel to and from the brain along nerves. Nerves are made of strings of long thin cells
neurons
travel across the synapse (a tiny gap) between neurons.
Neurotransmitters
controls voluntary muscle movements
Somatic nervous system
controls internal biological functions
Autonomic nervous system
at rear base of skull; most basic processes of life
Hindbrain
breathing, heart rate, reflexes
Medulla
bridge between spinal cord and brain, chemicals for sleep
Pons
