| facial index | Relation of the length of the face to its maximal width between the zygomatic prominences; to get (05 Mar 2000) |
|---|---|
| facial injuries | General or unspecified injuries to the soft tissue or bony portions of the face. (12 Dec 1998) |
| facial lymph nodes | A chain of lymph nodes lying along the facial vein that receive afferent vessels from the eyelids, nose, cheek, lip, and gums, and send efferent vessels to the submandibular nodes. Synonym: nodi lymphatici faciales. (05 Mar 2000) |
| facial motor nucleus | A group of motor neurons located in the ventrolateral region of the lower pontine tegmentum and innervating the facial muscles, the stapedius muscle in the middle ear, the posterior limb of the musculus digastricus, and the stylohyoid muscle. Synonym: nucleus nervi facialis, facial motor nucleus, motor nucleus of facial nerve, nucleus facialis. (05 Mar 2000) |
| facial muscles | Muscles of facial expression or mimetic muscles that include the numerous muscles supplied by the facial nerve that are attached to and move the skin of the face. (12 Dec 1998) |
| facial myokymia | Myokymia that appears in the facial muscles, causing narrowing of the palpebral fissure and continuous undulation of the facial skin surface; the latter is referred to as "bag of worms" appearance and is best seen with reflected light; due to intrinsic brainstem lesion, such as a pontine glioma or multiple sclerosis. (05 Mar 2000) |
| facial nerve | <anatomy, nerve> The facial nerve enervates the muscles of the face (facial expression). Lesion of the facial nerve cause a drooping to one side of the face, inability to wrinkle the forehead, inability to whistle, inability to close the eye and deviation of the mouth to the unaffected side. Synonym: cranial nerve VII. (27 Sep 1997) |
| facial neuralgia | <neurology> A disorder of trigeminal nerve (cranial nerve V) dysfunction. Synonym: tic douloureux. Characterised by excruciating paroxysms of pain in the lips, gums, cheek or chin, and, very rarely, in the distribution of the eye (ophthalmic division of the trigeminal nerve). (27 Sep 1997) |
| facial nucleus | A group of motor neurons located in the ventrolateral region of the lower pontine tegmentum and innervating the facial muscles, the stapedius muscle in the middle ear, the posterior limb of the musculus digastricus, and the stylohyoid muscle. Synonym: nucleus nervi facialis, facial motor nucleus, motor nucleus of facial nerve, nucleus facialis. (05 Mar 2000) |
| facial pain | Pain in the face including the orofacial and craniofacial regions. (12 Dec 1998) |
| facial palsy | <neurology> A condition that involves the facial nerve (VII cranial nerve) and results in the paralysis of one side of the face. Bell's (facial nerve palsy) can be differentiated from a central (stroke) deficit by the inability to raise the eyebrow on the affected side. (27 Sep 1997) |
| facial paralysis | Paralysis of the facial muscles, usually unilateral, due to either a lesion involving the nucleus or the facial nerve peripheral to the nucleus (peripheral facial paralysis) or a supranuclear lesion in the cerebrum or upper brainstem (central facial paralysis). With latter, facial weakness is usually partial and the upper portion of the face is relatively spared, due to bilateral cortical connections. (12 Dec 1998) |
| facial plane | A measurement of the bony profile of the face. Synonym: nasion-pogonion measurement. (05 Mar 2000) |
| facial plexus | An autonomic plexus on the facial artery derived from the external carotid plexus; it sends a branch to the submandibular ganglion. Synonym: external maxillary plexus, plexus maxillaris externus. (05 Mar 2000) |
| facial profile | The outline form of the face from a lateral view, the sagittal outline form of the face. (05 Mar 2000) |
