Submandibular duct

Wharton's ductWharton's Ducts
Secretions are delivered into the submandibular duct on the deep portion after which they hook around the posterior edge of the mylohyoid muscle and proceed on the superior surface laterally.
It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle at the base of the tongue.

Human mouth

mouthoral cavityfloor of mouth
The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.
It receives the secretions from the submandibular and sublingual salivary glands.

Frenulum of tongue

The excretory ducts are then crossed by the lingual nerve, and ultimately drain into the sublingual caruncles – small prominences on either side of the lingual frenulum along with the major sublingual duct.
They empty the submandibular (submaxillary) and sublingual salivary glands.

Mylohyoid muscle

mylohyoidMylohyoideus
The submandibular gland wraps around the edges of the mylohyoid, and is divided into superficial and deep lobes above and below the muscle.

Lingual nerve

linguallingual nervesnerve
The excretory ducts are then crossed by the lingual nerve, and ultimately drain into the sublingual caruncles – small prominences on either side of the lingual frenulum along with the major sublingual duct.
The nerve then passes between the medial pterygoid muscle and the ramus of the mandible, and crosses obliquely to the side of the tongue beneath the constrictor pharyngis superior and styloglossus, and then between the hyoglossus and deep part of the submandibular gland; it finally runs from laterally to medially inferiorly crossing the duct of the submandibular gland, and along the tongue to its tip becoming the sublingual nerve, lying immediately beneath the mucous membrane.

Salivatory nuclei

The superior salivatory nucleus innervates the submandibular gland and the sublingual gland and is part of the facial nerve

Sialolithiasis

salivary duct calculisalivary stonesalivary stones
The submandibular gland accounts for 80% of all salivary duct calculi (salivary stones or sialolith), possibly due to the different nature of the saliva that it produces and the tortuous travel of the submandibular duct to its ductal opening for a considerable upward distance.
Sialolithiasis (also termed salivary calculi, or salivary stones), is a condition where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct").

Parasympathetic nervous system

This nerve carries secretomotor fibers to the submandibular and sublingual glands.

Salivary gland

salivarysalivary glandsminor salivary gland
The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth. two other types of salivary glands are parotid and sublingual glands.
Humans have three paired major salivary glands (parotid, submandibular, and sublingual) as well as hundreds of minor salivary glands.

Submandibular ganglion

submaxillary ganglionsubmandibularsubmaxillary
It is situated above the deep portion of the submandibular gland, on the hyoglossus muscle, near the posterior border of the mylohyoid muscle.

Facial nerve

The facial nerve also supplies parasympathetic fibers to the submandibular gland and sublingual glands via chorda tympani.

Parotid gland

two other types of salivary glands are parotid and sublingual glands.
There are also two other types of salivary glands; they are submandibular and sublingual glands.

Chorda tympani

Here, the preganglionic fibers of the chorda tympani synapse with postganglionic fibers which go on to innervate the submandibular and sublingual salivary glands.

There are also two other types of salivary glands; they are submandibular and Parotid glands.

Mucous gland

The acini of each adenomere are composed of either serous or mucous cells, with serous adenomeres predominating.

Exocrine gland

Like other exocrine glands, the submandibular gland can be classified by the microscopic anatomy of its secretory cells and how they are arranged.

Serous demilune

Some mucous adenomeres may also be capped with a serous demilune, a layer of lysozyme-secreting serous cells resembling a half moon.

Glandular branches of facial artery

Glandular branches
The glandular branches of the facial artery (submaxillary branches) consist of three or four large vessels, which supply the submandibular gland, some being prolonged to the neighboring muscles, lymph glands, and integument.

Saliva

salivationspittlespit
The submandibular gland is one of the major three glands that provide the mouth with saliva.
In humans, the submandibular gland contributes around 70–75% of secretion, while the parotid gland secretes about 20–25% and small amounts are secreted from the other salivary glands.

Major sublingual duct

sublingual ductBartholin's duct
The excretory ducts are then crossed by the lingual nerve, and ultimately drain into the sublingual caruncles – small prominences on either side of the lingual frenulum along with the major sublingual duct.

Palpation

palpablepalpatedpalpate
The gland can be bilaterally palpated (felt) inferior and posterior to the body of the mandible, moving inward from the inferior border of the mandible near its angle with the head tilted forwards.

Adenomere

Lobes contain smaller lobules, which contain adenomeres, the secretory units of the gland.

Acinus

Each adenomere contains one or more acini, or alveoli, which are small clusters of cells that secrete their products into a duct.

Serous fluid

The acini of each adenomere are composed of either serous or mucous cells, with serous adenomeres predominating.
