2024年11月2日 · Both the submandibular gland and duct share an intimate anatomical relationship with three principal nerves; the lingual nerve, hypoglossal nerve and facial nerve (marginal mandibular branch). The courses of these nerves are briefly outlined:

The hypoglossal nerve runs forwards, crosses internal carotid artery, external carotid artery and loop of lingual before it enters the submandibular region by passing deep to the posterior belly of the digastric muscle.

2023年8月21日 · Nerves that course through and around the submandibular triangle are essential surgical landmarks to recognize as resection can lead to numerous adverse outcomes. The most superficial of these nerves include the marginal mandibular branch of the facial nerve superiorly and the cervical branch of the facial nerve inferiorly.

2023年10月31日 · The submandibular glands are small, paired exocrine glands, each located within the submandibular (digastric) triangle of the neck. Together with the parotid and sublingual glands, they make a set of major salivary glands that are the components of the accessory digestive system.

Echostructure: the submandibular gland is more hypoechoic than the parotid gland. Appearance: triangular shape with a posterior base. Rarely seen are normal intraglandular ducts. With stimulation (sialogogue), visualization may be easier.

The nerve fibers travel through the nervus intermedius and chorda tympani (a branch of the facial nerve), before joining the lingual nerve, which is a branch of the mandibular division of the trigeminal nerve (cranial nerve V).

The submandibular gland is a walnut-size irregular in shape gland. It is a mixed gland that secretes both mucus as well as serous but predominantly serous secretion in the body.

Superficial structures are grouped as. 1. Nerves. Lingual nerve, a branch of posterior division of mandibular division of trigeminal nerve. 2. Muscle: Styloglossus. 3. Structures related to word IIsubmandibular” Submandibular duct. 4. Veins accompanying it. 2. Deep. 1. Nerve: Glossopharyngeal nerve-9th cranial nerve. 2.

The submandibular ganglion is a small fusiform-shaped cluster of cell bodies of the parasympathetic nervous system. Parasympathetic innervation of the submandibular gland is not only responsible for the secretion of saliva, but it also plays a main role in the development and regeneration of the gland.

2018年6月1日 · Submandibular gland is supplied by branches from submandibular ganglion carrying following fibers: sensory fibers. Parasympathetic (Secretomotor) fibers: Preganglionic fibers originate from superior salivatory nucleus in pons. they pass successively through the facial nerve and a branch of facial nerve viz. chorda tympani.
