Reissner's fiber

Reissner's fiber is a fibrous aggregation of secreted molecules extending from the subcommissural organ (SCO) through the ventricular system and central canal to the ampulla caudalis, a small ventricle-like structure at the end of the spinal cord.[1] In vertebrates, Reissner's fiber is formed by secretions of SCO-spondin from the subcommissural organ into the spinal fluid of the ventricular cavity.[2] Reissner's fiber is highly conserved, and present in the central canal of all chordates.[2] In cephalochordates, Reissner's fiber is produced by the ventral infundibular organ, as opposed to the dorsal SCO.[3]
