Uberon definition : Part of the ventricular system of the brain, forming a single large irregularly shaped
cavity located on the midline of the rhombencephalon, between the medulla, pons and
the isthmus ventrally and the cerebellum dorsally. It is continuous with the cerebral
aqueduct anteriorally and the central canal of the spinal cord posteriorly. It communicates
with the subarachnoid space through its lateral and median apertures.;
Uberon synonym : ventricle IV;
Uberon related term : IVth ventricle; hindbrain ventricle; rhombencephalic ventricle; fourth ventricle proper; 4th ventricle; ventricle of hindbrain; ventricle of rhombencephalon;
Uberon narrow term : rhombencephalic vesicle;
Uberon Homology note : The early development of most vertebrate brains is similar (...). The zebrafish neural
tube follows the same basic differentiation pattern as the mammalian neural tube (reference
1); The brain develops from three embryonic enlargements of the neural tube, which
later differentiate into five regions. A forebrain differentiates into telencephalon
and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain
divides into the metencephalon and myelencephalon. Cavities within the brain enlarge
to form a series of interconnected ventricles (reference 2).[well established][VHOG];
