Functions of Brain RegionsGive the brain region for the functions described.Medulla Oblongata1.Contains vital centers that regulate heartbeat, breathing, blood pressure, vomiting,coughingCerebellum2.Smoothes and coordinates skilled skeletal muscle movement; also posture and balance or equilibriumPineal Gland3.Secretes melatonin that controls the sleep-wake cycleHypothalamus4.Controls and integrates the autonomic nervous system; regulates hormones, emotionalbehavior, temperature, eating, and drinking behavior
Cerebral Cortex5.Interprets sensory input, controls skilled skeletal muscle movements, and is involved in emotional and intellectual processesPons6.Helps control breathing; conducts impulses to and from the cerebellum, midbrain, and medullaThalamus7.Relays all sensory input to the cerebral cortex; involved in skeletal muscle actions and memory processingCorpora Quadrigemina8.Coordinates visual and auditory reflexesBasal Nuclei9.Coordinates gross, automatic muscle movements; also involved with the limbic systemCorpus Callosum10.White fiber tracts communicating between hemispheresC. Flow of Cerebrospinal Fluid
