Tracts Flashcards
Four ascending tracts
Dorsal column medial leminiscal, Anterolateral system, Spinocerebellar, Cuneocerebellar
Modalities carried by the DCML
Fine touch, Vibration, Conscious propriception
Terminal point of DCML
Cerebral cortex
Point of dessucation of the DCML
Medulla
Divisions of the anterolateral system
Anterior and lateral spinothalamic
Modalities carried by the anterior spinothalamic tract
Crude touch, Pressure
Modalities carried by the lateral spinothalamic tract
Pain, Temprature
Terminal point of the anterolateral system
Cerebral cortex
Point of dessucation of the anterolateral system
1-2 levels higher than it joins
Modalities carried by the spinocerebellar tract
Unconscious proprioception of the lower limbs
Terminal point of the spinocerebellar tract
Cerebellum
