AP PSYCHOLOGY

Detailed explanation-1: -The medulla oblongata is the rod-shaped part of the brain which is seen below the cerebrum, located near the cerebellum of the brain. It controls involuntary actions like heartbeat and breathing.

Detailed explanation-2: -The nervous system Your breathing usually does not require any thought, because it is controlled by the autonomic nervous system, also called the involuntary nervous system. The parasympathetic system slows your breathing rate. It causes your bronchial tubes to narrow and the pulmonary blood vessels to widen.

Detailed explanation-3: -The autonomic system, a complex subset of the peripheral nervous system, controls involuntary activities, such as heart rate, temperature, and the smooth muscle activity of the vascular and digestive systems.

Detailed explanation-4: -These vital mechanisms are controlled by one of the brain’s most durable parts–the brain stem. The brain stem is an automatic control center for many such important involuntary actions of the body. And, it is a pathway for impulses travelling back and forth between the body and the rest of the brain.

Detailed explanation-5: -Your medulla is where your cardiovascular and respiratory systems link together into a united system that controls your heart rate, breathing, blood pressure and more. Manages other automatic processes. These are things that your body often does without you having to think about them.
