Physiological changes (heart rate and blood pressure) Acute stress response (general adaptation syndrome: parasympathetic. The brain: the brain consists of 3 sections: Hindbrain- rudimentary, basic functions, old brain: the medulla: mediates heart rate, blood pressure and co2/o2 concentration, the pons: link between hindbrain and midbrain, and helps control respiration, the cerebellum: coordinates voluntary muscle movement, balance/equilibrium, muscle tone and posture. Midbrain: relay of sensory and motor information between forebrain and hindbrain, visual and auditory reflexes, production of da in substantia nigra. Forebrain: has 2 main sections: diencephalon and telencephalon, the diencephalon contains:
