Cord Ppt - Ascending And Descending Tracts Of Spinal

Slide 1: Introduction

Classic Presentation: Flaccid weakness at level of infarct, spastic below, with dissociated sensory loss.

: Sensory pathways that carry information (pain, temperature, touch) from the periphery to the brain. Descending Tracts : Motor pathways that carry commands from the brain to control muscles. Organization : Fibres are grouped into columns called (dorsal, lateral, and ventral). Slideshare 2. Major Ascending (Sensory) Tracts These tracts typically involve a three-neuron chain: (dorsal root ganglion), (spinal cord or brainstem), and (thalamus). SlideServe Tract Name Location of Decussation Lateral Spinothalamic Pain and temperature Spinal cord (immediate) Anterior Spinothalamic Crude touch and pressure Spinal cord (1–2 segments above) Dorsal Columns Fine touch, vibration, and conscious proprioception Medulla oblongata Spinocerebellar Unconscious proprioception for coordination Mostly ipsilateral (same side) 3. Major Descending (Motor) Tracts These are divided into (voluntary movement) and Extrapyramidal (involuntary/postural) systems. TeachMeAnatomy Pyramidal Tracts (Corticospinal) Lateral Corticospinal
