Autonomic Nervous System:
The autonomic nervous system moves the impulses from the blood vessels, the heart, all organs in the chest, abdomen, and pelvis to other parts of the brain. Those being, the medulla, pons, and hypothalamus. These impulses reach reflex responses, allowing appropriate reactions of the heart, vascular system, and all the organs of the body. There are two major components of the autonomic nervous system, the sympathetic and the parasympathetic systems. They convey impulses form sensory organs, muscles, circulatory system, all the organs of the body to the centers in the medulla, pons, and hypothalamus. From here the two systems carry the impulses throughout the entire body. The sympathetic system reaches the organs through the spinal cord where the messages are given to the other nerves of the body. Through the nervous system, the autonomic nerves release stimuli causing unconscious, reflex bodily adjustments. Those being, the size of the pupil, digestive function, and rate of respiration. The autonomic nervous system prepares the body for the "flight or fight response" by increasing heart rate and blood pressure.
