three basic anatomic parts of the brain - ANSWER brainstem, cerebellum, cerebrum
pons - ANSWER regulate sleep, respiration, swallowing, bladder control, hearing,
equilibrium, taste, eye movement, facial expressions, facial sensation, posture
medulla oblongata (Myelencephalon) - ANSWER regulates autonomic, involuntary
functions through vasomotor centers
ie. breathing, HR, BP
Midbrain (mesencephalon) - ANSWER impacts motor control, sleep/wake cycles,
alertness, vision, hearing, temperature regulation
brainstem - ANSWER controls innate and automatic self preserving behavior patterns
AKA primal brain, reptilian brain, trunk of the brain
Consists of pons, medulla, and midbrain
