| peripheral facial paralysis | 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) |
| root of facial nerve | <anatomy, nerve> Fibres running from the facial motor nucleus upward to the facial colliculus where they curve around the abducens nucleus and then pass peripherally between the superior olive and sensory nucleus of the trigeminal, to emerge as the facial nerve from the pontomedullary groove. Synonym: radix nervi facialis. (05 Mar 2000) |
| common facial vein | <anatomy, vein> A short vessel formed by the union of the facial vein and the retromandibular vein, emptying into the jugular vein; considered to be a continuation of the facial vein in the NA. Synonym: vena facialis communis. (05 Mar 2000) |
