As a result some NE tends to diffuse out of the synapse into the surrounding tissues, where it may exert an effect. So the effects of sympathetic stimulation are more wide spread and last longer the parasympathetic stimulation.

Anatomy Review: Digestive System

Page 4: Parasympathetic and sympathetic nerves innervate the GI tract • Both parasympathetic and sympathetic divisions of the autonomic nervous system control digestion by contacting the enteric nervous system in the wall of the digestive tract • The parasympathetic division typically stimulates ...

What is the Autonomic Nervous System?

Parasympathetic preganglionic fibres leave the CNS in both cranial and sacral nerves; the so-called "cranio-sacral outflow". Cranial fibres arise from specific parasympathetic brainstem nuclei of cranial nerves III, VII, IX, and X.

Short-Term Autonomic Control in the Cardiovascular System

Acute changes in blood pressure bring about changes in sympathetic and parasympathetic activity to homeostatically adjust heart rate and blood flow and thereby regulate blood pressure (2,3,6,).

The Role of Autonomic Nervous System in Rapid Breathing Practices

The relationship between the respiration and parasympathetic is manifested as sinus arrhythmia , the heightened form of which can be seen during deep breathing.

The Autonomic Nervous System

• M1 receptors stimulate gastric acid secretion • M2 receptors are thought to mediate the negative chronotropic effects of parasympathetic stimulation • M3 receptors mediate lacrimal and salivary gland secretion, and may also be involved in gut smooth muscle contraction.
