Promotes rest and digest functions, focusing on energy conservation and restoration.

Another name for the parasympathetic system, with fibers from the brainstem and sacral region.

Cranial nerve 10, providing about 90% of parasympathetic innervation.

Long fibers that synapse within target organs or terminal ganglia.

Short fibers facilitating quick responses in target organs.

Ganglia very close to target organs where synapses occur.

Decreased by the parasympathetic system to conserve energy.

Narrowing of airways in the lungs to conserve energy.

Increased movement and secretion promoting digestion.

Contraction of bladder muscles and relaxation of sphincters.

Optimizes close vision, indicating a relaxed state.

Target organ where preganglionic fibers synapse.

Ganglia serving similar purposes to terminal ganglia but less close.

Nerves from the brainstem involved in parasympathetic innervation.

Nerves from the sacral region involved in parasympathetic innervation.
