Introduction

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.
