Human Embryonic Ventricular Timeline | ||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Week | Carnegie Stage | Event | ||||||||||||||||||
Week 4 | Stage 11 | appearance of the optic ventricle. The neural groove/tube space is initially filled with amniotic fluid. | ||||||||||||||||||
Stage 12 | closure of the caudal neuropore, onset of the ventricular system and separates the ependymal from the amniotic fluid. | |||||||||||||||||||
Stage 13 | cavity of the telencephalon medium is visible. | |||||||||||||||||||
Week 5 | Stage 14 | cerebral hemispheres and lateral ventricles begin, rhomboid fossa becomes apparent. | ||||||||||||||||||
Stage 15 | medial and lateral ventricular eminences cause indentations in the lateral ventricle | |||||||||||||||||||
Week 6 | Stage 16 | hypothalamic sulcus is evident. | ||||||||||||||||||
Stages 17 - 18 | interventricular foramina are becoming relatively smaller, and cellular accumulations indicate the future choroid villi of the fourth and lateral ventricles. | |||||||||||||||||||
Week 7 | Stage 18 | areae membranaceae rostralis and caudalis are visible in the roof of the fourth ventricle, and the paraphysis is appearing. | ||||||||||||||||||
Stage 19 | choroid villi are visible in the fourth ventricle, and a mesencephalic evagination (blindsack) is visible | |||||||||||||||||||
Week 8 | Stage 20 | choroid villi are visible in the lateral ventricle. | ||||||||||||||||||
Stage 21 | olfactory ventricle is visible. | |||||||||||||||||||
Stages 21-23 | lateral ventricle has become C-shaped (anterior and inferior horns visible). Recesses develop in the third ventricle (optic, infundibular, pineal). | |||||||||||||||||||
| ||||||||||||||||||||
