Document Summary
Cerebellum: recall, the cerebellum is behind the brainstem, underneath the cerebrum. Once it enters brain stem and cerebellum, the latter can tell if it"s going according to plan or if corrections are necessary. The part of the cerebellum more on the side is more involved in movement of the limbs. Many parts of the cerebellum also coordinate movements of speech and of our eyes. Brainstem: brainstem basically connects all parts of the nervous system: the cerebrum, cerebellum, and spinal cord. It also connects all the cranial nerves: inside of the brain stem has some similarities to the spinal cord, particularly in the medulla. This is the reticular formation of the brain stem. Long tracts are collections of axons that often connect the cerebrum to the spinal cord. In addition to the reticular formation, there are collections of neuron somas that are distinct nuclei. Cranial nerves often carry info into or away from these nuclei.
