Reissner's fiber

Reissner's fiber
Anatomical terminology

Reissner's fiber (named after Ernst Reissner) is a fibrous aggregation of secreted molecules extending from the subcommissural organ (SCO) through the ventricular system and central canal to the terminal ventricle, a small ventricle-like structure near 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 ventricular cerebrospinal fluid.[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]
