Ventral (or anterior/front) is efferent – motor – movement Ventral horn (anterior horn) – anterior horn cell White matter (myelinated) and grey matter (cell bodies) of spinal cord Spinal nerves (dorsal root and anterior root)

Ascending tracts (sensory) – from periphery to brain Examples of ascending tracts: spino-thalamic; dorsal column-medial lemniscus; spino-reticluar Descending Tracts (motor) – from brain to periphery Examples of descending tracts - pyramidal tract; extra-pyramidal tract;
