Descending Tracts Of Spinal Cord Ppt - Ascending And

Understanding these tracts is vital for diagnosing spinal cord injuries. For instance, Brown-Séquard syndrome (a hemisection of the cord) results in:Ipsilateral loss of motor function and fine touch (Corticospinal and Posterior Columns).Contralateral loss of pain and temperature (Spinothalamic Tract). Summary for Presentation

A color-coded cross-section of the cord showing exactly where decussation happens. ascending and descending tracts of spinal cord ppt

Consists of the fasciculus gracilis (lower body) and fasciculus cuneatus (upper body). It carries fine touch, vibration, and conscious proprioception. Spinothalamic Tracts: Lateral: Pain and temperature. Anterior: Crude touch and pressure. Understanding these tracts is vital for diagnosing spinal
