Originates in the brain stem and lower part of the spinal cord

Usage examples of parasympathetic.

But parasympathetic stimulation was not HARMFUL INTENT 101 expected with a local anesthetic like Marcaine.

Marcaine was given, the patients got a sudden and striking parasympathetic reaction with abdominal pain, salivation, perspiration, and even miotic pupils.

But he remembered enough to know that the sympathetic division of the autonomic nervous system was the part affected by local anesthetics, not the parasympathetic part apparently affected in the Noble and Owen cases.

But there is no way to explain sudden marked parasympathetic stimulation.

Something that not only causes seizures and heart toxicity, but also, for a brief instance, parasympathetic stimulation.

Karen Hodges had initially suffered the same baffling parasympathetic symptoms before the onset of her seizure.

Presto: parasympathetic symptoms before all hell breaks loose secondary to the nerve and muscle cell destruction.

It did say that the toxin stimulated the parasympathetic system and produced muscle twitches.

But parasympathetic stimulation was not expected with a local anesthetic like Marcaine.

One of the master switches to move back and forth between the sympathetic and parasympathetic nervous systems was defective.

It was designed to respond to the presence of parasympathetic energy, and PS waves always meant Spookies.

The parasympathetic nerve fibers, on the other hand, act to slow the heartbeat, contract the pupil of the eye and the bronchi of the lungs and stimulate the activity of the alimentary canal muscles.

Oppositely, the parasympathetic fibers, where present, dilate the first set of blood vessels and constrict the second.

The parasympathetic division, in contrast, acts to bring the body back from its emergency posture when the need is passed.

When they passed, the parasympathetic nervous system, the part that was in charge during sleep and ran all the automatic systems, came back with a vengeance.
