The sympathetic division is referred to as this term because its nerve fibers exit the spinal column in the chest and abdominal regions:

• thoracolumbar

• craniosacral

• craniothoracic

• thoracosacral

Branch of the PNS that carries signals to internal organs, smooth and cardiac muscles, and glands

• autonomic nervous system

• basal nervous system

• somatic nervous system

• central nervous system

Division of the autonomic nervous system that prepares your body for activity, and responses like fight or flight:

• sympathetic division

• central division

• somatic division

• parasympathetic division

In the autonomic division, this place where neurons meet is located close to the spinal cord to ensure excitatory messages can be quickly spread through the body:

• sympathetic ganglia

• parasympathetic ganglia

• afferent neurons

• efferent neurons

Division of the autonomic nervous system that calms the body so that digestion can occur and energy can be put into storage:

• sympathetic division

• peripheral division

• parasympathetic division

• central division

Set of neurons in the autonomic nervous system that are distal to the ganglia, are relatively long in the sympathetic division, and relatively short in the parasympathetic:

• afferent fibers

• sensory fibers

• postganglionic fibers

• preganglionic fibers

The set of neurons in the autonomic nervous system that are proximal to the ganglia, are relatively short in the sympathetic division, and relatively long in the parasympathetic:

• preganglionic fibers

• sensory fibers

• autonomic fibers

• postganglionic fibers

In the autonomic division, this place where neurons meet is located close to the effector organs so that messages tend to be very specific to that organ:

• sympathetic ganglia

• parasympathetic ganglia

• postganglionic neuron

• preganglionic neuron

Parasympathetic division is referred to as this term because its nerve fibers exit the CNS near the head and hips:

• craniothoracic

• chest-abdominal

• craniosacral

• lumbosacral

This neurotransmitter is released by all postganglionic neurons in the sympathetic division of the autonomic nervous system:

• dopamine

• acetylcholine

• norepinephrine

• sodium
