The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
These include facial nerve weakness, rapid increase of the size of the lump as well as ulceration of the mucosa of the skin. [13] Mucoepidermoid carcinoma is a common malignant tumour of the salivary glands and has a low incidence of 4–13%. [13] Adenoid cystic carcinoma is also a common malignant salivary gland lesion and has an incidence of ...
Located in the jugular foramen. Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus. Some sensation is also relayed to the brain from the palatine tonsils. This nerve is involved together with the vagus nerve in the gag reflex. X Vagus
The parotid plexus or plexus parotideus is the branch point of the facial nerve (extratemporal) after it leaves the stylomastoid foramen. This division takes place within the parotid gland . Branches
The Heerfordt-Waldenstrom syndrome consists of sarcoidosis with parotid enlargement, fever, anterior uveitis, and facial nerve palsy. [2] IgG4-related sialadenitis: This term refers to IgG4-related disease (IgG4-RD) involving any of the major salivary glands, i.e. parotid or submandibular glands. This is often symmetrical and is usually ...
Thus the facial artery can be used as an important landmark in locating the marginal mandibular nerve during surgical procedures. [2] Damage can cause paralysis of the three muscles it supplies, which can cause an asymmetrical smile due to lack of contraction of the depressor labii inferioris muscle . [ 3 ]
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The symptoms include inflammation of the eye , swelling of the parotid gland, chronic ... facial nerve palsy and anterior uveitis.
