Document Summary

Fasciculus gracilus (lower limbs) and fascilculus cuneates (upper limbs). Ascend to level of ventral posterolateral nucleus of thalamus to synapse. Goes onto post central gyrus to primary sensory cortex. But there are also convoluated mechanosensory pathways from the body to the cerebellum for unconscious proprioception *dr. scott* From main sensory nucleus of cn 5 and mesencephalic nucleus of trigeminal lemniscus. The main sensory neurons cross over in the pons and and join the medial lemniscus and synapse in the thalamus on the vpm (ventral posteromedial) nucleus of the thalamus. It heads even more lateral than the afferents for the body in primary sensory cortex. *mesencephalic nucleus carries information from the masseter muscle spindles and other mechanoreceptors* Information from the primary and secondary sensory cortices is relayed to the posterior parietal cortex and other association areas where information is interpreted. From the posterior parietal cortex information is passed onto the inferior parietal cortex and temporal parietal junction and angular gyrus.
