| These folds include the falx cerebri, and the tentorium, which separates the cerebral hemispheres from the cerebellum. |
| A third, the falx cerebelli, projects downward from the tentorium cerebelli between the two cerebellar hemispheres. |
| In the falx is a poison-sac from which poison flows through the hollow fang and out at its tip. |
| One of these, the falx cerebri, is a sickle-shaped partition lying between the two hemispheres of the brain. |
| From this septum is formed the falx cerebri and other parts. |
| It is divided into two hemispheres by the falx cerebri, a partition which follows the middle line of the skull. |
