| crossed paralysis | alternating hemiplegia |
| crossed phrenic phenomenon | Hemisection of the cord above the exit of the phrenic nerve paralyzes the ipsilateral half of the diaphragm; if the contralateral phrenic nerve is then sectioned or blocked, contractions on the ipsilateral side are resumed. (05 Mar 2000) |
| crossed pyramidal tract | Those fibres of the pyramidal tract that cross to the opposite side in the pyramidal decussation and descend in the dorsal half of the lateral funiculus of the spinal cord; they are distributed throughout the length of the spinal cord to interneurons of the zona intermedia of the spinal gray matter. See: pyramidal tract. Synonym: tractus corticospinalis lateralis, tractus pyramidalis lateralis, crossed pyramidal tract, fasciculus corticospinalis lateralis, fasciculus pyramidalis lateralis, lateral corticospinal tract, lateral pyramidal fasciculus.

| galactose tolerance test | A liver function test, based on the ability of the liver to convert galactose to glycogen, measured by the rate of excretion of galactose following ingestion or intravenous injection of a known amount; normally, less than 3 g appear in the urine within 5 hours after the ingestion of 40 g.
