Visceromotor function

The visceromotor system describes the movements of the involuntary musculature or, in a narrower sense, the movement of the viscera , i.e. the motor system that comes about through visceroefferent signals. The term is used, for example, to classify nerve fibers or parts of nerves that are responsible for controlling the smooth muscles of the intestine or the vessels .

Classification

In the case of the cranial nerves , the following fiber qualities are further divided:

General visceromotor

This refers to the autonomic fibers of the cranial parasympathetic nervous system , which supply the smooth muscles and are responsible for the secretory innervation of the head glands and the glands of the mucous membrane of the digestive tract. These fibers are found in the following cranial nerves:

• Oculomotor nerve
• Trigeminal nerve
• Facial nerve
• Glossopharyngeal nerve
• Vagus nerve

Special visceromotor

These include fibers that pull to the parts of the striated muscles that have emerged from the gill arches (for example, the facial muscles ). These fibers can be found in:

• Trigeminal nerve
• Facial nerve
• Glossopharyngeal nerve
• Vagus nerve
• Accessory nerve
