plural term
brain ventricles


external definition

Organ cavity of the brain which consists of the lateral ventricles, the third and fourth ventricles and the cerebral aqueduct[BIRNLEX:1356].

external ontology notes

FMA draws the distinction between e.g. 'fourth ventricle' and 'cavity of fourth ventricle'. The latter is a cavity, and part of the former, which is a region. The superclass of 'fourth ventricle' is_a 'region of ventricular system of the brain'. We place this class here, although it is not equivalent to ventricles, as it includes ventricle bodies.
