Medial lemniscus

was changed:
Medial lemniscus (ML), also know as the Reil's band, is an ascending bundle of myelinated axons from the gracile and cuneate nuclei, after they decussate in the medulla oblongata 1.
It is part of the larger dorsal column medial lemniscus pathway, important for conveying the sensation for fine (discriminative) touch, vibration and conscious proprioception.
Course
Gracile and cuneate nuclei are second-order sensory neurones which receive peripheral input from the first-order neurones in the gracile fasciculus and the cuneate fasciculus of the dorsal columns. These nuclei send out axons called the internal arcuate fibers, which become the medial lemniscus after they decussate in the medulla oblongata 1,2.
Medial lemniscus terminates in the ventral posterior nucleus of the thalamus, where it synapses with the third-order neurones which transmit information to the postcentral gyrus of the cerebral cortex 1,2.
