Ascending And Descending Tracts Of Spinal Cord Ppt

: Internal arcuate fibers in the lower medulla, forming the medial lemniscus. B. Spinothalamic Tracts (Anterolateral System)

Fine touch, vibration, and conscious proprioception (position sense). Key Tracts: Fasciculus gracilis (lower body) and Fasciculus cuneatus (upper body). Decussation (Crossing over): Occurs in the medulla oblongata. B. Spinothalamic Tracts Lateral Spinothalamic: Carries sensations of pain and temperature Anterior Spinothalamic: crude touch and pressure Decussation: ascending and descending tracts of spinal cord ppt

– Innervation of cranial nerve nuclei; head and neck motor control. : Internal arcuate fibers in the lower medulla,

Lateral Corticospinal: Crosses (decussates) in the medulla, controlling limb movements. controlling limb movements.
