Salivatory nuclei

The Salivatory nuclei (pronunciation: /səˈlɪvəˌtɔːri ˈnjuːkliːaɪ/) are a pair of nuclei in the brainstem that are involved in the production and secretion of saliva.

Etymology

The term "salivatory nuclei" is derived from the Latin words "saliva", meaning "spit", and "nucleus", meaning "core" or "center".

Function

The salivatory nuclei are responsible for controlling the secretion of saliva from the salivary glands. They receive input from various parts of the brain and send signals to the salivary glands to either increase or decrease saliva production. This process is crucial for maintaining oral health, aiding in digestion, and facilitating speech.

Anatomy

The salivatory nuclei are located in the lower part of the pons, a region of the brainstem. They consist of two main parts: the superior salivatory nucleus and the inferior salivatory nucleus. The superior salivatory nucleus controls the secretion of the submandibular gland and the sublingual gland, while the inferior salivatory nucleus controls the parotid gland.
