alar plate(s), artifact(s), basal plate, basis pedunculi area, cerebral aqueduct (mesocoele), cerebral artery, cerebral vein, ectoderm, ectomeninx, edge of myelencephalon (medulla oblongata), endomeninx, interpeduncular fossa, junction of mesencephalon and metencephalon, median sulcus, mesencephalon, metencephalon, rhombencoel (fourth ventricle), rhombic lip (cerebellum), roof of rhombencoel (fourth ventricle), sulcus limitans, tectum, tegmentum, trochlear nerve (CN IV)

A section through the ventral part of the mes- and metencephalon junction and edge of the myelencephalon.

Observe:
1. The minute trochlear nerve coursing ventrally at the lateral aspect of the junction region.
2. The continuity of the basal plates in the junction region.
3. The interpeduncular fossa separating the basis pedunculi areas.
4. The narrow portion of the mesocoele, which is becoming the cerebral aqueduct.
5. The roof of the fourth ventricle joining the dorsal edge of the myelencephalon.
