Parotid gland

__CONTENTLESS__ The parotid gland, also called the parotid gland, is the largest salivary gland.

Anatomy and Histology
A purely serous tuboalveolar branched gland, which is located on the outside of the ``m. masseter, extends cranially to the ``arcus zygomaticus, posterior to the auricle and passes up to proc. styloideus. Caudally, it goes to the neck in front of the m. sternocleidomastoideus and the posterior belly m. digastricus. The n. facialis (VII cranial nerve) comes to it, which branches in it and forms the plexus parotideus.

The outer surface of the gland together with the masseter m. is covered by the fascia parotideomasseterica. The deep sheet of this fascia is involved in separating the gland from the "pterygoideus medialis" and from all the surrounding muscles. The Tractus angularis separates the gland from the trigonum submandibulare.

The duct of the parotid gland (ductus parotideus, Stensen's duct), 5-6 cm long, passes over the front edge of the masseter muscle and opens into the oral cavity at the height of the second upper molar.

The gland produces about one third of the total amount of saliva, the secretion is relatively rich in amylase.

It contains serous alveoli, plasma cells, myoepithelial cells. We find inserted, annealed and interlobular ducts. It is typical for the parotid gland to contain many fat cells.

Vascular and nerve supply
The arteries to the gland area. temporalis superficialis, a. maxillaris, a. auricularis posterior and ' 'a. transversa faciei''.

The veins come from the ''vv. parotideae''.

The Nodi parotidei conduct lymph to the superficial and deep neck nodes.

Sympathetic fibers come along the arteries, parasympathetic fibers follow the path of the so-called Jacobson's anastomoses.
