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.

Abstract. A major function of the nervous system is to control the relative constancy of the internal environment of the organism. That is, to provide the right chemical environment for living processes to take place. This control of the internal environment is known as homeostasis.

The autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response. It is, however, constantly active at a basic level to maintain homeostasis homeodynamics.

The role of the parasympathetic nervous system is to relax the body, and return us to our 'normal' resting state. Consequently, the parasympathetic nervous system slows down our heart rate and breathing rate, and reduces our blood pressure.

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 main functions of the central nervous system is to PROCESS information received through sensory systems and other parts of the body and to activate appropriate actions to the external/internal stimuli.

Key Points The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.

What is the role of the nervous system in the heartbeat regulation? The body regulated BP by neurotransmitters released by the sympathetic nervous system increasing the heart rate. Those released by the parasympathetic nervous system decreases it. ... Contracting the relaxation of the smooth muscles in the body.

Ian Cuming / Getty Images. The autonomic nervous system regulates a variety of body process that takes place without conscious effort. The autonomic system is the part of the peripheral nervous system that is responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.

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.

What does the nervous system do? The nervous system along with the endocrine (hormonal) system works to control all activities within the human body. It does this by communicating messages between the brain and the body very quickly using nerve impulses (action potentials).

The autonomic nervous system and its sympathetic arm play important roles in the regulation of blood pressure. Their role in the short-term regulation of blood pressure, especially in responses to transient changes in arterial pressure, via baroreflex mechanisms is well known.

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.

Further, the parasympathetic nervous system plays a vital role in maintaining both mental and physical health by helping the body to calm down from stress reactions that elevate blood pressure, dilate the pupils, and divert energy from other body processes to fighting or fleeing.
