The spelling of the word "glandula salivalis interna" is complex and requires a knowledge of Latin morphology and spelling conventions. The first word, "glandula," is spelled with a 'g' instead of a 'j' because Latin did not distinguish between the two sounds. The second word, "salivalis," includes a 'v' instead of a 'u' because Latin spelled the sounds interchangeably. The final word, "interna," includes a silent 'a' and a 'c' that sounds like an 's' because of Latin pronunciation rules. The IPA transcription for this word is /ɡlændjʊlə səlaɪvəlɪs ɪntɛrna/.
Glandula salivalis interna refers to the internal salivary gland, which is one of the major types of salivary glands found in the human body. Salivary glands are responsible for the production and secretion of saliva, an essential fluid that aids in the digestion of food by moistening and lubricating it.
The glandula salivalis interna is situated deep within the oral cavity and comprises a pair of glands in the posterior part of the mouth, known as the parotid glands. These glands are located below the zygomatic arch, behind the mandibular ramus, and in front of the ear. Each gland is encapsulated and is made up of numerous lobes, which are interconnected by a ductal system that eventually leads to the oral cavity.
The primary function of the glandula salivalis interna is to secrete saliva, a watery fluid containing enzymes, electrolytes, mucus, and antibacterial compounds. Saliva performs multiple crucial roles, including initiating the digestion of starches and lipids, neutralizing the pH within the oral cavity, aiding in the formation of a food bolus, facilitating speech and swallowing, and maintaining optimal oral hygiene. Additionally, saliva helps protect the teeth and surrounding tissues against microbial growth and tooth decay. The glandula salivalis interna is innervated by the glossopharyngeal nerve (CN IX) and is under the control of the autonomic nervous system, particularly the parasympathetic division.
