part of part of transformation of telencephalon telencephalic ventricle A brain ventricle that is part of a telencephalon. In mammals and species with an evaginated telencephalon, this is one of a pair of lateral structures, one in each hemisphere BAMS:LV BAMS:Tel-V BM:Tel-LV BTO:0000879 CALOHA:TS-1230 DHBA:10596 DMBA:126651562 EFO:0001961 EHDAA2:0001984 EHDAA:3502 EHDAA:6576 EMAPA:16914 EV:0100307 FMA:78448 GAID:611 HBA:9419 MA:0000192 MBA:81 MESH:D020547 OpenCyc:Mx4rvYsFdZwpEbGdrcN5Y29ycA TAO:0000696 Telencephalic ventricles 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] The lateral ventricles are part of the ventricular system of the brain. Classified as part of the telencephalon, they are the largest of the ventricles. The lateral ventricles connect to the central third ventricle through the interventricular foramina of Monro[WP]. The two lateral ventricles are a cavity in each of the cerebral hemispheres derived from the cavity of the embryonic neural tube. They are separated from each other by the septum pellucidum, and each communicates with the third ventricle by the foramen of Monro, through which also the choroid plexuses of the lateral ventricles become continuous with that of the third ventricle[GO].
