What does the salivatory nucleus do?

The superior salivatory nucleus receives afferent information from the hypothalamus and olfactory system as well as taste information from the mouth cavity. It supplies the sublingual salivary glands and the nasal and palatine glands.

What does the inferior salivatory nucleus do?

The inferior salivatory nucleus gives rise to general visceral efferent fibers that provide input for parotid gland secretion. The afferent limb for autonomic reflexive control of respiration and cardiac output is provided by general visceral afferent fibers of the glossopharyngeal nerve.

Where is the salivatory nucleus?

The salivatory nuclei are the superior salivatory nucleus, and the inferior salivatory nucleus that innervate the salivary glands. They are located in the pontine tegmentum in the brainstem.

What are cranial nerve nuclei?

The cranial nerve nuclei are aggregate of cells (collection of cell bodies). Attached to these cell bodies are fibers called cranial nerves (bundles of axons). These nuclei are either sensory or motor but never both.

What does glossopharyngeal nerve do?

As stated above, the glossopharyngeal nerve provides motor innervation to the stylopharyngeus muscle, which is responsible for elevating the pharynx and larynx.

What nerve controls salivation?

The parotid mainly produces watery, or serous saliva. It’s duct opens in the mouth just opposite the crown of the 2nd upper molar tooth. The gland’s productions are predominantly controlled by a nerve called the glossopharyngeal nerve which originates in the superior salivatory nucleus of the medulla in the brainstem.

Is Salivatory a word?

Salivatory meaning Associated with or accompanied by salivation.

What is the difference between a nuclei and a ganglia?

Clusters of cell bodies in the central nervous system are called nuclei, while the cell bodies lining the nerves in the peripheral nervous system are called ganglia.

What vital functions are regulated by brainstem nuclei?

It is responsible for many vital functions of life, such as breathing, consciousness, blood pressure, heart rate, and sleep. The brainstem contains many critical collections of white and grey matter. The grey matter within the brainstem consists of nerve cell bodies and form many important brainstem nuclei.

What is the major function of the glossopharyngeal nerve quizlet?

The glossopharyngeal nerve is cranial nerve IX. Its major motor function is to help in swallowing.

Which is a function of the Glossopharyngeal IX nerve quizlet?

It provides sensory information about taste, sensation to the tongue and pharynx and information from chemo/baro-receptors in the carotid artery.

Does the vagus nerve control salivation?

Vagal afferent stimulation significantly increased salivation and swallowing-like events in a frequency-dependent manner.
