How does the sympathetic nervous system act?

Answer 1

The autonomic nervous system that controls the functions within the body. Some functions that it controls are the heartbeat, digestive system, and breathing. The autonomic nervous system is the part of the peripheral nervous system that acts as a control system. It functions largely below the level of consciousness to control visceral functions.

Answer 2

The Parasympathetic Nervous System is a branch of the Autonomic Nervous System (ANS), like the Sympathetic Nervous Sysyem. The ANS is concerned with controlling all the functions of you body that you do no want to have t obe thinking about constantly, like keeping your hear beeting or your stomach churning. The two braches parasympathetic and sympathetic are usually in contrast. The sympathetic nervous system is activated when the body percieves itself to be in danger. This activates the Fight Or Flight response, ie it increases the heart rate, increases the breathing rate, dilates the pupils etc to prepare the to be ready to either face the danger or get away from it. At the same time is diverts blood from areas that are not required at in an emergency, such as the gastric tract, to other areas that are requires, such asthe skeletal muscle. The parasympathetis brach does the opposite. When there is no danger percieved the body can concentrate on its desire to Rest And Digest. Thy parasympathetic branch brings heart rate back down to a resting level and rediverts the bloob back to the grastrointestinal tract from the skeletal muscle. This branch is activated shortly after a meal as well, that is why you should not go swimming after a meal, or both the branches will be activated anc the body will be fighting against itself. Although sometime the two systems do work together, for example in the male during sex. The sympathetic system stimulates erection whilst the parasympathetic stimulates ejaculation.

Answer 3

It stems off the Automic Nervous System, which in itself is in the Peripheral Nervous System. The Sympathetic Nervous System activates when your body is aroused, and stimulates the 'Fight or Flight' response. It secretes adrenalin into your system and gets the body ready or action.

Answer 4

The autonomic nervous system consists of two parts and controls what happens in our body.The sympathetic nervous system prepares the body for action and is often thought of as the fight or flight response. The parasympathetic nervous system is in charge of the more tranquil functions.

Answer 5

The sympathetic nervous system is involved in the stimulation of activities that prepare the body for actions called fight-or-flight responses (responses that serve to fight off or retreat from danger).

The parasympathetic nervous system activates tranquil functions as in eating and digesting. It is sometimes called the rest-and-repose response.

Generally, both sympathetic and parasympathetic systems target the same organs, but often have opposite reactions.

Answer 6

it is the excitatory system. "fight or flight" response

Answer 7

it contains chiefly adrenergic fibers and tends to depress secretion, decrease the tone and contractility of smooth muscle, and increase heart rate.
