a. cerebellum
b. neural center
c. neural tube
d. embryonic tube

Match the primary brain vesicles names with themselves:
- forebrain
- midbrain
- hindbrain
a. mesencephalon
b. prosencephalon
c. rhombencephalon
- b
- a
- c
T/F
The midbrain divides into telencephalon (“endbrain”), and diencephalon (“Interbrain”).
False
Midbrain remains undivided.
- the primary vesicles give rise to the secondary brain vesicles. Forebrain divides into telencephalon ("endbrain"), and diencephalon ("Interbrain"), and the hindbrain constricts, forming the metencephalon ("afterbrain") and myelencephalon ("spinal brain").
Match the following major structures of the brain with what they form
- diencephalon
- mesencephalon
- metencephalon
- myelencephalon
- all midbrain and hindbrain structures
a. midbrain
b. pons and cerebellum
c. brain stem
d. medulla oblongata
e. forms the hypothalamus, thalamus, epithalamus, and retina of eye.
- e
- a
- b
- d
- c

b. medial longitudinal and transverse cerebral fissure
Which of the following is NOT a major lobe in the cerebral cortex?

c. epithalamus
Which cranial nerve does not affect the pons?
a. trigeminal
b. trochlear
c. abducens
