	During week 5 the five secondary brain vesicles form from the original primary vesicles formed in week 4 (see also [[BGDA_Practical_7_-_Week_5#Neural_Development\|Additional Information]]).		During week 5 the five secondary brain vesicles form from the original primary vesicles formed in week 4 and the cranial end of the neural tube now has 3 flexures (bends).
