What Three Dilations Form at the Cephalic End of the Neural

Question

What three dilations form at the cephalic end of the neural tube at four weeks?
A) Telencephalon, rhombencephalon, metencephalon
B) Prosencephalon, mesencephalon, rhombencephalon
C) Myelencephalon, metencephalon, mesencephalon
D) Rhombencephalon, prosencephalon, diencephalon

Accepted Answer

The three primary brain vesicles that form at the cephalic end of the neural tube at around four weeks of embryonic development are the prosencephalon (forebrain), mesencephalon (midbrain), and rhombencephalon (hindbrain). These vesicles later differentiate into all the major structures of the adult brain.
