,REVIEW OUTLINE

1. White Matter vs Grey Matter

Overview of 2. Ascending Vs Descending Tracts
○ Motor vs Sensory

Spinal Cord 3. Ascending Sensory Tract Localization
○ Anterolateral Pathways - Spinothalamic Tracts

and Spinal ○ Dorsal Column Medial Lemniscal Tracts
○ Spinocerebellar Tracts


Tracts 4. Descending Motor Tract Localization
○ Anterior Corticospinal Tract
○ Lateral Corticospinal Tract
○ Rubrospinal Tract
○ Reticulospinal Tract
○ Vestibulospinal Tract

, White Matter vs Grey Matter

Grey Matter:
● Location of neuron cell bodies
● Point of communication between neurons

White Matter
● Location of Axons bundles
● Serves to transmit signals to other regions of
the brain, spinal cord, and body
