What is the nervus intermedius?

The nervus intermedius, which is the peripheral part of the facial nerve, has visceral motor and special sensory fibers. First described in 1563, the nerve was referred to as “portio media inter comunicantem faciei et nervum auditorium” by Heinrich August Wrisberg in 1777 (1).

What is nervus intermedius neuralgia?

Nervus intermedius neuralgia is an extremely uncommon pain syndrome in which the pain is very similar to that of trigeminal neuralgia but in the distribution of n. intermedius. Generally it is presumed that its etiology is the cross compression of the nerve at its central-peripheral myelin junction.

Where is the nervus intermedius?

facial nerve
The intermediate nerve, nervus intermedius, nerve of Wrisberg or Glossopalatine nerve, is the part of the facial nerve (cranial nerve VII) located between the motor component of the facial nerve and the vestibulocochlear nerve (cranial nerve VIII). It contains the sensory and parasympathetic fibers of the facial nerve.

What does the intermediate nerve do?

The intermediate nerve contains autonomic (parasympathetic) as well as general and special sensory fibres. Preganglionic autonomic fibres, classified as general visceral efferent, project from the superior salivatory nucleus in the pons.

Which branches does Intermedius nerve give off?

This nerve transports the nerves of taste for the anterior two-thirds of the tongue and contains secretory fibers for the sublingual and submaxillary glands. In addition, it sends a branch to the auditory tube.

What is neuralgia pain?

What is the nucleus Solitarius?

The nucleus of the solitary tract, also known as the nucleus tractus solitarius (pl. solitarii) is a pair of cell bodies found in the brainstem. This structure, along with its tract (the solitary tract or tractus solitarius), has far reaching impacts on many homeostatic systems within the body.
