Open in 3D

The gracile fasciculus carries sensory information from the lower half of the body entering the spinal cord at the lumbar level.

The cuneate fasciculus carries sensory information from the upper half of the body (upper limbs, trunk, and neck) entering the spinal cord at the cervical level.

The gracile fasciculus is wedge-shaped on transverse section and lies next to the posterior median septum.

Its base is at the surface of the spinal cord, and its apex directed toward the posterior gray commissure.

The gracile fasciculus increases in size from inferior to superior.
