what is the main function of the sympathetic nervous system?

Sympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.

The sympathetic nervous system (SNS) is one of two main divisions of the autonomic nervous system (ANS). Its general action is to mobilize the body's fight-or-flight response. Control the body's response while at rest. Control the body's response during perceived threat.

Cardiovascular System. The primary function of the heart and blood vessels is to transport oxygen, nutrients, and byproducts of metabolism.

The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions.

Central Nervous System The brain is the body's main control center. The main function of the CNS is the integration and processing of sensory information. It synthesizes sensory input to compute an appropriate motor response, or output.

Of all the body systems, the nervous system is the major control system of homeostasis. It provides monitoring, response, and regulation of all systems in the human body and other organisms. It functions from the tiny level of individual cells to affecting the whole body at once.

The nervous system is the body's main communication system; it gathers, synthesizes, and uses data from the environment. The most basic unit of the nervous system is the neuron, which serves as both a sensor and communicator of internal and external stimuli.

Definition of sympathetic nervous system : the part of the autonomic nervous system that contains chiefly adrenergic fibers and tends to depress secretion, decrease the tone and contractility of smooth muscle, and increase heart rate — compare parasympathetic nervous system.

The parasympathetic nervous system calms the body and conserves energy. It is responsible for our rest and digest response.

The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.[1]

The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement. The brain consists of multiple regions responsible for different functions, whereas the spinal cord has one main function.

The main function of the PNS is to connect the central nervous system(CNS) to the limbs and organs, essentially serving as a communication relay going back and forth between the brain and the extremities. Neurons -The cells that make up the nervous system are called neurons.

The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body. ... The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system.

The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.
1123036
The primary function of the somatic nervous system is to connect the central nervous system to the body's muscles and control voluntary movements and reflex arcs. Information taken in by sensory systems is transmitted to the central nervous system.

The sympathetic division of the autonomic nervous system prepares the body for physical activity by increasing heart rate, blood pressure and respiration. The sympathetic division also stimulates the release of glucose from the liver for energy.

The primary function of the peripheral nervous system is to connect the brain and spinal cord to the rest of the body and the external environment.
