Where is the inferior Salivatory nucleus found?

Where is the inferior Salivatory nucleus found?

Where is the inferior Salivatory nucleus found?

upper medulla
The inferior salivatory nucleus is a small nucleus in the upper medulla that innervates the otic ganglion with GVE fibers of the glossopharyngeal nerve. The otic ganglion provides parasympathetic innervation to the parotid gland.

What cranial nerves control salivation?

Cranial Nerve 9 – Glossopharyngeal (IX) The sensory component of the glossopharyngeal nerve conveys information about taste and other sensations from the throat and the posterior third of the tongue. The motor component of this nerve controls the acts of swallowing and salivation, and the dilation of blood vessels.

What is submandibular ganglion?

The submandibular ganglion (SMG) is a parasympathetic ganglion, which receives inputs from preganglionic cholinergic neurons and innervates the submandibular salivary gland to control saliva secretion.

What does the nucleus ambiguus do?

The nucleus ambiguus is the location of cell bodies of motor nerves that innervate the ipsilateral muscles of the soft palate, pharynx, larynx and upper esophagus and are mainly responsible for swallowing and speaking.

What nerve controls your smile?

It is a muscle of facial expression which draws the angle of the mouth superiorly and posteriorly to allow one to smile. Like all muscles of facial expression, the zygomatic major is innervated by the facial nerve (the seventh cranial nerve), more specifically, the buccal and zygomatic branches of the facial nerve.

Which cranial nerve is responsible for smiling?

Cranial Nerve VII
Facial Nerve or Cranial Nerve VII The most important nerve controlling muscles of facial expression, including those involved in a smile, is unsurprisingly called the facial nerve, also known as cranial nerve VII.

What do cranial nerve nuclei do?

The cranial nerve nuclei are made up of the neurons in the brainstem that receive primary sensory inputs or that give rise to motor outputs.

Which cranial nerve nuclei are located in the midbrain?

The midbrain of the brainstem has the nuclei of the oculomotor nerve (III) and trochlear nerve (IV); the pons has the nuclei of the trigeminal nerve (V), abducens nerve (VI), facial nerve (VII) and vestibulocochlear nerve (VIII); and the medulla has the nuclei of the glossopharyngeal nerve (IX), vagus nerve (X).

What are the branches of the submandibular ganglion?

Submandibular ganglion

  • small ganglion suspended from the undersurface of the lingual nerve.
  • inferior to submandibular duct sitting on the hyoglossus muscle.
  • supplies secretomotor fibers to the sublingual and submandibular salivary glands.
