| tonic epilepsy | An attack in which the body is rigid. (05 Mar 2000) |
| tonic pupil | Usually a unilateral abnormality of the eye characterised by slow pupillary constriction to light and in which there is a delayed reaction to changes in accommodation and convergence. The affected pupil is usually larger. (12 Dec 1998) |
| tonic reflex | The occurrence of an appreciable interval after the production of a reflex before relaxation, e.g., the leg remains up for a time after a knee jerk. Synonym: Gordon's symptom. (05 Mar 2000) |
| tonic seizure | Sustained contractures of skeletal muscle as occur during convulsions. Synonym: tonic convulsion. (05 Mar 2000) |
| tonic spasm | A continuous involuntary muscular contraction. (05 Mar 2000) |
| epilepsy, tonic-clonic | Primary generalised epileptic seizures, starting without warning, characterised by loss of consciousness, tonic contraction of muscles, loss of postural control, and production of a cry by the forced expiration of air due to contraction of the respiratory muscles. The individual then falls to the floor and remains rigid for a few seconds, after which a series of rhythmic contractions occur in all four limbs. This clonic phase can last for a variable period, ending only upon muscle relaxation. Upon recovery, there is a gradual return to consciousness, disorientation, amnesia for the seizure, sometimes retrograde amnesia as well, headache, and drowsiness. The individual may not return to baseline functioning for days. (12 Dec 1998) |
| anterior cerebellar notch | A wide, shallow notch on the anterior surface of the cerebellum occupied laterally by the superior cerebellar peduncles and the inferior quadrigeminal bodies medially. Synonym: anterior notch of cerebellum, incisura cerebelli anterior, semilunar notch. (05 Mar 2000) |
| anterior inferior cerebellar artery | <anatomy, artery> Origin, basilar; distribution, lower surface of lateral lobes of cerebellum, choroid plexus in cerebellopontine angle; anastomoses, posterior inferior cerebellar; usual source of labyrinthine artery. Synonym: arteria cerebelli inferior anterior. (05 Mar 2000) |
| ganglionic layer of cerebellar cortex | The layer of Purkinje cells between the molecular and granular layers of the cerebellar cortex. Synonym: stratum neuronorum piriformium, ganglionic layer of cerebellar cortex, layer of piriform neurons, Purkinje's layer, stratum gangliosum cerebelli. (05 Mar 2000) |
| cerebellar | <anatomy> Pertaining to the cerebellum. (18 Nov 1997) |
| cerebellar arteries | An artery related to and supplying the cerebellum. See: anterior inferior cerebellar artery, posterior inferior cerebellar artery, superior cerebellar artery. (05 Mar 2000) |
| cerebellar astrocytoma | <oncology, tumour> This primary brain tumour of the cerebellum accounts for 10 to 30% of brain tumours in children. The are usually slow growing and benign. Symptoms include gait problems, clumsiness, headache and vomiting. Treatment often involves a combination of surgery, radiation therapy and chemotherapy. (27 Sep 1997) |
| cerebellar ataxia | Loss of muscle coordination caused by disorders of the cerebellum. (05 Mar 2000) |
| cerebellar atrophy | A degeneration of the cerebellum, particularly the Purkinje cells, as the result of abiotrophy or of toxic agents, as in alcoholism. (05 Mar 2000) |
