depression artifact, mesencephalon (midbrain), mesocoele (midbrain ventricle), metencephalic part of rhombencephalon, myelencephalic part of rhombencephalon, rhombencoel (fourth ventricle), rhombic lip, roof of rhombencoel (fourth ventricle), roof plate (dorsal), trochlear nerve rootlets (CN IV)

A section through the roof of the fourth ventricle and origin of the trochlear nerve.

Observe:
1. The dorsal edge of the met- and myelencephalic parts of the rhombencephalon.
2. The large fourth ventricle with its thin roof.
3. The ventricle of the caudal part of the mesencephalon.
