Parts of the Braina. Mesencephaloni. Midbrain; also relays information to higher brain centerii. Process auditory and visual information, reflexesb. Metencephaloni. Cerebellum and pons ii. Further down toward spinal cordiii. Coordinate movement of skeletal muscle, aid in learning motor skillsc. Myelencephaloni. Medulla oblongataii. Integration centers- Cardiac center (heart), vasomotor center (vessels), respiratory center (breathing).iii. Also involved in sneezing, vomiting, hiccupping, swallowing, sweatingII. Spinal Corda. Carries nerves from brain to the rest of the body and back againb. Neural circuits acts as integration centers for spinal reflexesc. Do not have to think about spinal
