The Brain By: Andrew Baccaro & Robert Keller Cerebrum Largest part of the human brain Divided into 4 sections High brain functions such as thought and action Temporal Lobe Associated with emotional responses, hearing, memory and speech Anterior to the occipital lobes Lateral to the Fissure of Sylvius Occipital Lobe Controls vision and color recognition Most caudal portion of the cerebral cortex Parietal Lobe Controls cognition, information process, pain and touch sensation, spatial orientation, speech, and visual perception Superior to the occipital lobes Posterior to the fissure and frontal lobes Frontal Lobe Controls motor functions, higher order functions, planning, reasoning, judgment, impulse control, and memory Anterior portion of the cerebral cortex Cerebellum (little brain) Important role in motor control Helps provide smooth, coordinated body movements Cerebellum Anatomy Most neurons than rest of brain combined, only 10% of brain volume. Made up of very tightly folded layer, cerebellar cortex. If unfolded, would be 1 meter long and 5 cm wide. Cerebellum Structure A: Midbrains B: Pons C: Medulla D: Spinal Cord E: Fourth Ventricle F: Arbor vitae G: Tonsil H: Anterior Lobe I: Posterior Lobe Medulla Oblangata Located above the spinal cord, below the pons, and anterior to the cerebellum 2 parts Open part (close to pons) Closed part (further down by spinal cord) Medulla cont. Controls autonomic functions, and relays nerve signals between the brain and spinal cord. Controls several major points and autonomic functions of the body Respiration, blood pressure, swallowing, vomiting, defecation.
