- C. Spino thalmamic tract
- D. Spinocerebellar tract

Pain and temperature sensations from the limbs and trunk ascend mainly in the anterolateral system, especially the lateral spinothalamic tract. The dorsal columns carry fine touch, vibration and proprioception, while corticospinal and spinocerebellar tracts are primarily motor or coordination pathways.
