Primary Anatomical Considerations continued
  • Sensory pathways or tracts
    • Spinothalamic tracts
      • Anterolateral spinothalamic tracts (ALSpTh)
        • Nociceptive (pain), thermal, and crude touch
    • Fibers cross to opposite side of spinal cord within a few segments
  • Dorsal Columns/ Medial Lemniscus system (DC/ML)
    • Discriminatory touch
      • Stereognosis
      • Barognosis
      • Graphesthesia
      • Texture recognition
    • Two-point discrimination
    • Pressure
    • Kinesthesia
    • Proprioception
    • Vibration
      • Fibers remain uncrossed until the level of the medulla
  • Spinocerebellar Tracts (SC) - Unconscious sensation for motor control
  • Primary synaptic connections within the brain
    • Thalamus, Somatosensory cortex. Reticular formation, Cerebellum and Vestibular cortex.
