The sympathetic division of the autonomic nervous system maintains internal organ homeostasis and initiates the stress response. Physiological changes induced by the sympathetic nervous system include accelerating the heart rate, widening bronchial passages, decreasing motility of the large intestine, dilating the pupils, and causing perspiration. Stress—as in the hyperarousal of the flight-or-fight response—is thought to counteract the parasympathetic system, which generally works to promote maintenance of the body at rest. Sympathetic nervous system : The sympathetic nervous system extends from the thoracic to lumbar vertebrae and has connections with the thoracic, abdominal aortic, and pelvic plexuses. The sympathetic nervous system is responsible for regulating many homeostatic mechanisms in living organisms.

What Is the Autonomic Nervous System?

The peripheral nervous system includes both a voluntary, somatic branch and an involuntary branch that regulates visceral functions. Examples of body processes controlled by the ANS include heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, urination, and sexual arousal. The peripheral nervous system PNS is divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system SoNS is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The SoNS consists of efferent nerves responsible for stimulating muscle contraction, including all the non-sensory neurons connected with skeletal muscles and skin. The somatic nervous system controls all voluntary muscular systems within the body, and also mediates involuntary reflex arcs.

What Is the Autonomic Nervous System?

Autonomic Nervous System. The nervous system captures and processes stimuli acting on an organism and provides the means for an adequate response. It provides neural control that is faster than hormonal pathways and is, therefore, more suitable for transmitting information that requires a rapid, coordinated response.
