Name: central canal
Synonyms: canalis centralis, neural lumen
Definition: Spinal cord structure that is part of the ventricular system and is filled with cerebral-spinal fluid and runs the length of the spinal cord.
Ontology: Anatomy Ontology [ZFA:0000938]
Name: cerebrospinal fluid circulation
Synonyms: cerebrospinal fluid flow, CSF circulation, CSF flow
Definition: The neurological system process driven by motile cilia on ependymal cells of the brain by which cerebrospinal fluid circulates from the sites of secretion to the sites of absorption. In ventricular cavities, the flow is unidirectional and rostrocaudal, in subarachnoid spaces, the flow is multi-directional.
