| For horizontal planes, ________ is used when referring to the brain while _______ is used when referring to the spinal cord. | Brain: horizontal plane Spinal cord: transverse plane |
| Name the 3 vesicles in the earlier stage of neural development | 1. Prosencephalon 2. Mesencephalon 3. Rhombencephalon |
| The Prosencephalon becomes _________ and ___________. Which in turn develops into ____________ and __________. | Telencephalon and diencephalon. Telencephalon develops into cerebral hemispheres. Diencephalon develops into thalamus and hypothalamus. |
