| facial tic | Involuntary twitching of the facial muscles, sometimes unilateral. Synonym: Bell's spasm, convulsive tic, facial spasm, histrionic spasm, mimic convulsion, mimic spasm, mimic tic, palmus, prosopospasm. (05 Mar 2000) |
| facial tics | <neurology> A repetitive spasmodic movement of the eyes or facial muscles. May also involve the neck or shoulders. Tics are most common in children.

| lingual-facial-buccal dyskinesia | A syndrome of potentially irreversible, involuntary, dyskinetic movements that may develop in patients who have been treated with antipsychotic medications (for example phenothiazines) longer-term. Other drugs known to cause tardive dyskinesia include: tricyclic antidepressants, selegiline, clozapine, levamisole and metoclopramide. (27 Sep 1997) |
| abducens nerve | <anatomy, nerve> The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibres to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control. (12 Dec 1998) |
