Somatic and Autonomic Nervous Systems Essay

The paper represents a comparative analysis of somatic and autonomic nervous systems, which regulate the major body control systems. According to the medical theory, the somatic nervous control refers to all voluntary body movements while autonomic system regulates involuntary impulses of a human body. Specifically, an autonomic nervous system manages such divisions as connections between spinal, brain, and other organs. In contrast to it, the system of voluntary control concerns the connections between neurons and human muscles (“The Somatic and Autonomic Nervous Systems” par. 2).Somatic and Autonomic Nervous Systems Essay

Two systems play a critical role in regulating the major organism functions. For instance, autonomic nervous control relates to such processes as digestion, perspiration, the utilization of body energy as well as the management of sexual and temperature arousals. The system of involuntary impulses realizes its major functions through the revelation of two subdivisions such as parasympathetic and sympathetic nervous regulations. The first system refers to the smoothing of all body functions. Mainly, sympathetic regulation embraces the stimulation of normal blood circulation, the restriction or extension of bronchial size, delivering regulatory effects through digestion mediation as well as catalyzing the basic sexual arousal effects (Stroetmann and Bowald, 21).Somatic and Autonomic Nervous Systems Essay

The sympathetic system provides the opposite effect by delivering nervous stimulation (“Sympathetic Nervous System” par. 6). Mainly, the regulation is responsible for enhancing the flows of blood and leading them to the muscles, increasing heart rate and lungs’ diameter, constricting urinary sphincters, and stimulating orgasm reaction. In contrast to autonomic nervous system, the somatic regulatory mechanism embraces a different set of functions. Specifically, the system acts through the stimulation of nerve impulses, which concern the contraction of muscles and sending commands to different body areas (Westfall 23).
