Autonomic nervous system is one of the two subdivisions of the nervous system; the other being the somatic nervous system. The autonomic nervous system regulates and controls bodily functions and processes without conscious control or voluntary input (e.g. pumping blood around your body or digesting food). It is further subdivided into the sympathetic and parasympathetic systems; categorized by the neurotransmitters utilized and the physiological functions.
Sympathetic = "fight or flight"
Parasympathetic = "rest & digest" system
Both are part of the autonomic nervous system.
Longer than a sentence but I'm sure you cut it down somehow!

That is by convention you put it into central nervous system. Tomorrow you can put the brain only in central nervous system and the spinal cord in the peripheral nervous system. This is anatomical classification. Physiologically the nervous system is single unit.
The autonomic nervous system also has two divisions: the sympathetic division and the parasympatheticdivision. These two divisions have antagonistic (opposing) effects on the internal organs they innervate (send nerves to act on).The sympathetic division, shown at the left, is the emergency system. It prepares the body to put out energy and to protect it from effects of injury. It shuts the gut down, speeds up the heart, increases blood pressure, dilates (makes bigger) the pupils of the eyes, makes more glucose (blood sugar) available in the blood for energy, etc. Cannon described these reactions as preparation for fight or flight (running away).The parasympathetic division, shown at the right, is the "housekeeping" division. It acts to replace and recover from the activities of living. Its action is (almost always) the opposite of the sympathetic division. It activates the gut for digestion, slows the heart rate, decreases the blood pressure, etc.

"The Importance of the brain to the nervous system" is one of the good grabbers for essay on why the nervous system is important.
The type of sentence you provided is not grammatically correct. It seems to be missing a subject. A corrected version could be "You were nervous on the day of the speech." This is a declarative sentence.

To put it plainly there is a system overload of sorts, and the body essentially stalls momentarily.
