: Leads to flaccid paralysis, muscle atrophy, and loss of reflexes. Brown-Séquard Syndrome : Hemisection of the cord results in ipsilateral loss of motor function/fine touch and contralateral loss of pain/temperature. SlideServe for any of these specific slides?

Consists of the Fasciculus Gracilis (lower limbs) and Fasciculus Cuneatus (upper limbs). It handles fine touch, vibration, and conscious proprioception. Spinothalamic Tracts: Lateral: Pain and temperature. Anterior: Crude touch and pressure.

The spinothalamic system handles more primitive or urgent sensations.Lateral Spinothalamic Tract: Transmits pain and temperature.Anterior Spinothalamic Tract: Transmits crude touch and pressure.Sensory neurons in this pathway typically cross over almost immediately upon entering the spinal cord. The Spinocerebellar Tracts
