| Name: | midbrain hindbrain boundary constriction |
|---|---|
| Synonyms: | MHBC |
| Definition: | A portion of tissue that is the deepest point of the fold of the midbrain hindbrain boundary. In zebrafish the midbrain hindbrain boundary constriction (MHBC) is formed soon after neural tube closure. The MHBC is formed by the bending of the basal side of the neuroepithelium. |

| Name: | midbrain-hindbrain boundary morphogenesis |
|---|---|
| Synonyms: | isthmus morphogenesis, MHB morphogenesis |
| Definition: | The process in which the anatomical structure of the midbrain-hindbrain boundary is generated and organized. The midbrain-hindbrain domain of the embryonic brain is comprised of the mesencephalic vesicle and the first rhombencephalic vesicle at early somitogenesis stages. An organizing center at the boundary patterns the midbrain and hindbrain primordia of the neural plate. |
