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.
The zygomatic branches of the facial nerve (malar branches) are nerves of the face.They run across the zygomatic bone to the lateral angle of the orbit.Here, they supply the orbicularis oculi muscle, and join with filaments from the lacrimal nerve and the zygomaticofacial branch of the maxillary nerve (CN V 2).
V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the ...
The temporal branch of the facial nerve is typically found between the temporoparietal fascia (i.e., superficial temporal fascia) and temporal fascia (i.e., deep temporal fascia). This layer is also known as the innominate fascia. There are several methods using anatomic landmarks that may be used to find the temporal branch of the facial nerve.
The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth. Branches
In the middle cranial fossa, the nerve is situated between the two layers of the dura mater [1]: 450, 498 and passes obliquely anterior-ward [1]: 450 along a groove upon the floor of the fossa [1]: 509 - the groove for the greater petrosal nerve - that is situated upon the anterosuperior aspect of the petrous part of the temporal bone [3]: 842 ...
Its parasympathetic root is derived from the nervus intermedius (a part of the facial nerve) through the greater petrosal nerve.. In the pterygopalatine ganglion, the preganglionic parasympathetic fibers from the greater petrosal branch of the facial nerve synapse with neurons whose postganglionic axons, vasodilator, and secretory fibers are distributed with the deep branches of the trigeminal ...
Tumour of facial nerve like schwannomas and perineuromas. Other tumours that can compress facial nerve along its course like congenital cholesteatomas, hemangiomas, acoustic neuromas, parotid gland neoplasms, or metastases of other tumors. Other causes like viral, bacterial or fungal infections like chicken pox, streptococcal infection or ...
