Document Summary
Feel free to email me (oneclass512475@gmail. com) if you have any questions or don"t understand something! Discuss anatomical landmarks and functions of the cerebellum. Discuss cerebellum"s connections to the rest of the cns. While the cerebral cortex controls activity, the cerebellum coordinates the cerebrally-activated movements to make sure they are smooth movements. Maintains posture and equilibrium/proprioception through coordination of vestibular sense from the ear. Higher cognitive function: motor memory/skill (e. g. shooting a puck, language, problem solving, task planning. The cerebellum maintains ipsilateral control over the body. Rule of 3"s: 3 lobes: anterior, posterior, flocculonodular lobe. Flocculonodular lobe can be seen on the ventral side, sandwiched between anterior and posterior lobe: 3 regions of types of matter (gray, white, gray, 3 steps of processing information, 3 peduncles which connect it to the brain stem. Vermis: connects two sides of the posterior lobe. Information is sent from the cerebellum to the cerebrum to resolve the difference between intended movements and current position.
