Submandibular gland

The paired -scale submandibular gland or Latin submandibular gland ( in domestic animals as mandibular gland called ) is one of the three major salivary glands. It is a mixed seromucous gland and produces with the other glands along the saliva ( Saliva). The submandibular gland provides the main part of the total amount of saliva. It lies on both sides of the mandible angle, submandibular between the mandible and the digastric muscle in the so-called trigone.

The excretory duct of the gland ( submandibular duct, Wharton's duct ) opens along with the major sublingual gland on the Hungerwarze ( caruncle sublingual ), a small papilla at the side of the lingual frenulum.

Side of the submandibular gland lie the submaxillary lymph nodes ( submandibular lymph ). From less experienced people the palpable salivary gland may be mistakenly confused with lymph nodes swelling.

The innervation of the submandibular gland is done by the autonomic nervous system. The parasympathetic nerve fibers originate from the chorda tympani, a branch of the seventh cranial nerve (facial nerve ). These fibers join the lingual nerve, submandibular ganglion to reach so ( in animals ganglion mandibular called ) where they are switched and then drag to the mandibular and sublingual salivary gland.
