Question

This structure in an embryo is the precursor to the medulla in an adult.

1. prosencephalon

2)	mesencephalon

3)	rhombencephalon

4)	posterior neural tube

This structure will become the adult cerebrum.

Question 2 options:

1)	prosencephalon

2)	mesencephalon

3)	rhombencephalon

4)	posterior neural tube

Answer 1

During embryonic development neural tube enlarges into three primary vesicles :

• Prosencephalon(forebrain):It on development form Cerebrum ,Thalamus ,hypothalamus and Epithalamus.
• Mesencephalon(midbrain):It on development form midbrain.
• Rhombencephalon(hind brain): It on development form Pons ,cerebellum and medulla oblongata.

1. Medulla develops from Rhombencephalon .Thus Option 3 is correct.

2.Cerebrum develops from prosencephalon.Thus Option 1 is correct.
