Though the parotid gland is the largest, it provides only 25% of the total salivary volume. The serous cell predominates in the parotid, making the gland secrete a mainly serous secretory product. [10] The parotid gland also secretes salivary alpha-amylase (sAA), which is the first step in the decomposition of starches during mastication. It is ...
The submandibular glands (previously known as submaxillary glands) are a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. [6] The secretion produced is a mixture of both serous fluid and mucus , and enters the oral cavity via the submandibular duct or Wharton duct. [ 7 ]
The parotid duct is formed when several interlobular ducts, the largest ducts inside the parotid gland, join.It emerges from the parotid gland. It runs forward along the lateral side of the masseter muscle for around 7 cm. [2] In this course, the duct is surrounded by the buccal fat pad.
In anatomy and physiology, a duct is a circumscribed channel leading from an exocrine gland or organ. Types of ducts ... Striated duct in parotid gland.
There are three pairs of main salivary glands and between 800 and 1,000 minor salivary glands, all of which mainly serve the digestive process, and also play an important role in the maintenance of dental health and general mouth lubrication, without which speech would be impossible. [11] The main glands are all exocrine glands, secreting via ...
The transverse facial artery is given off from the superficial temporal artery before that vessel leaves the parotid gland; running forward through the substance of the gland, it passes transversely across the side of the face, between the parotid duct and the lower border of the zygomatic arch, and divides into numerous branches, which supply the parotid gland and parotid duct, the masseter ...
Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus. Some sensation is also relayed to the brain from the palatine tonsils. This nerve is involved together with the vagus nerve in the gag reflex. X Vagus: Both sensory and motor
It is a complication of surgery involving the parotid gland whereby injury to these branches, which innervate the parotid gland and sweat glands of the face respectively, form abnormal connections. Salivation leads to perspiration and flushing of the pre-auricular region and is called 'gustatory sweating'.
