This results in a permanently dilated pupil that does not constrict in the presence of light. Chemotherapy is a less common choice in salivary malignancies. Around eight short ciliary nerves arise from the ganglion and pierce the eyeball adjacent to the optic nerve. The facial artery leads a tortuous path, which passes through the gland capsule before crossing over the inferior border of the mandible. Parasympathetic Innervation: CN VII provides pre ganglionic parasympathetic innervation to: Submandibular glands Sublingual glands Lacrimal glands Mucous membranes of the nose, palate, and pharynx It is important to note that all of the post ganglionic parasympathetic nerve fibers from CN VII are actually carried to their ultimate targets via divisions of CN V. The nerve functions in a secretomotor capacity. Blood Supply and Lymphatics Blood Supply The submandibular glands receive their primary blood supply from the submental and sublingual arteries, which are branches of the facial artery and lingual artery, respectively, both of which are branches of the external carotid artery. Most tumors present with an asymptomatic floor of the mouth or inferior, mandibular swelling and present similarly to benign conditions making diagnosis difficult. Its exact function is not well specified -?

    The submandibular ganglion is part of the human autonomic nervous system. It is one of four parasympathetic ganglia of the head and neck Contents. Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system. These paired ganglia supply all parasympathetic innervation to the head and neck.

    It has the three roots of a parasympathetic ganglion. It curves through the middle ear, along the superior aspect of the tympanic membrane, and departs through the anterior canaliculus. These fibres then pass along the internal surface of the sclera to the cornea, iris and ciliary body.

    Structure and Function The submandibular gland is the second largest salivary gland only the parotid gland is larger. It also possesses its own cardiac branch. It arises as a thin nerve from the internal carotid plexus, with the post-ganglionic cell bodies lying in the superior cervical ganglion. It is closely associated with the mandibular nerve V 3.

    In man preganglionic parasympathetic fibres reach the otic ganglion via the lesser may provide weak innervation to sweat glands around the lips (List and Peet, methionine) are seen in nerve fibers that supply cerebral blood vessels [2​]. The inferior salivatory nucleus sends preganglionic fibers to the otic ganglion, which in turn supplies the parotid gland with secretomotor fibers.

    provide weak innervation to sweat glands around the lips (Wilson, ; List and Peet, ).
    It is found between the optic nerve and the lateral rectus.

    Other secretomotor fibres of unknown origin are also distributed to the mucosa associated with the maxillary nerve. Embryology The submandibular gland develops after the parotid gland in the sixth week of prenatal development. Orbital branches pass through the superior orbital fissure The nasopalatine nerve passes through the sphenopalatine foramen and runs along the nasal septum. Sympathetic input also increases salivary secretion and can induce local inflammation.

    It passes anteriorly and inferiorly and enters the oral cavity through the incisive foramen.

    The sublingual caruncula is located in the floor of the mouth and is on either side of the lingual frenulum. Parasympathetic innervation in the head and neck promotes the production of mucous, tears, and saliva and is counter regulated by sympathetic innervation.
