The gracilis fasciculus ( lat. , Dt. The graceful bundle ) is a nerve pathway within the spinal cord . He conducts exteroceptive and proprioceptive information, especially from the lower extremity to the brain. This is known as epicritical sensitivity. The gracilis fasciculus belongs to the posterior cord tracts of the spinal cord with the cuneatus fasciculus .
The nerve fibers of the gracilis fasciculus run on the same side (ipsilateral) without prior switching to the gracilis nucleus in the medulla oblongata , where they are switched to the second neuron. After this switchover, they continue as a lemniscus medialis , in which the crossing takes place on the opposite side (contralateral).
The gracilis fasciculus is also known as the Goll bundle . The name goes back to the first description of the anatomical structure in 1860 by the Swiss neuroanatomist Friedrich Goll .
