what is the function of sympathetic nervous system?
17265
The sympathetic nervous system connects the internal organs to the brain by spinal nerves. When stimulated, these nerves prepare the organism for stress by increasing the heart rate, increasing blood flow to the muscles, and decreasing blood flow to the skin.

The autonomic nervous system, together with the hypothalamus, regulates pulse, blood pressure, breathing, and arousal in response to emotional cues. When activated, the sympathetic nervous system prepares the body for emergency actions by controlling the glands of the endocrine system.

sympathetic nervous system stimulates the eccrine sweat glands to secrete water to the skin surface, where it cools the body by evaporation. Thus, eccrine sweat is an important mechanism for temperature control. ... The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature.

Peripheral Nervous System Functions The peripheral nervous system connects the brain and the spinal cord to the rest of the body and the external environment. It regulates the internal homeostasis. It can regulate the strength of the muscle contractility.

Key Points The nervous system is a highly integrated 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.

Difference between Sympathetic And Parasympathetic Nervous System. The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.

First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.

The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles.

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 main function of the central nervous system is to process information from stimuli and respond. process information from responses and sense stimuli. sense stimuli and cause reactions in the body.
327255
The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.
337545
At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors.

 The autonomic nervous system (ANS) regulates the activities of cardiac muscle, smooth muscle, and glands.
571440
The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response. The sympathetic nervous system (SNS) is one of two main divisions of the autonomic nervous system (ANS).

The sympathetic nervous system is responsible for regulating many homeostatic mechanisms in living organisms. Fibers from the SNS innervate tissues in almost every organ system and provide physiological regulation over diverse body processes including pupil diameter, gut motility (movement), and urinary output.

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.
822058
The primary function of nervous tissue is to receive stimuli and send the impulse to the spinal cord and brain. The brain sends back a response to the muscles via the nerves. Impulses are sent along a series of nerves at about 300 mph.
