Preferred Label : gracile fasciculus;
Uberon definition : A group of axons that are from neurons involved in proprioception from the lower trunk
and lower limb[GO]. The fasciculus gracilis (tract of Goll) is a bundle of axon fibres
in the dorsomedial spinal cord that carries information about fine touch, vibrations,
and conscious proprioception from the lower part of the body to the brain stem. It
is part of the posterior column of the spinal cord, which also contains the fasciculus
cuneatus, which carries the same information from the upper part of the body. This
tract and its continuation in the brain stem is often referred to as the posterior
column-medial lemniscus pathway. The fasciculus gracilis is wedge-shaped on transverse
section and lies next the posterior median septum, its base being at the surface of
the medulla spinalis, and its apex directed toward the posterior gray commissure.
It increases in size from below upward, and consists of long thin fibers that are
derived from the posterior nerve roots, and ascend as far as the medulla oblongata,
where they end in the nucleus gracilis. The tract of Goll was named after Swiss neuroanatomist
Friedrich Goll[WP].;
