Does the nervous system, make you nervous?

Question

The title is quiet explanitary

Answer 1

No, the nervous system does not make us nervous. Whether one becomes nervous depends primarily on his or her personality. Environmental factors are secondary and the immediate causes. Of course, the sympathetic component of the nervous system in concert with the adrenal medullary catecholamines (together called the sympathoadrenal system) cause the manifestations.

Answer 2

The nervous system of vertebrate animals is often divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists of all other nerves and neurons that do not lie within the CNS. The large majority of what are commonly called nerves (which are actually axonal processes of nerve cells) are considered to be PNS. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system.

The somatic nervous system is responsible for coordinating the body's movements, and also for receiving external stimuli. It is the system that regulates activities that are under conscious control.

The autonomic nervous system is then split into the sympathetic division, parasympathetic division, and enteric division. The sympathetic nervous system responds to impending danger or stress, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement one feels due to the increase of adrenaline in the system. The parasympathetic nervous system, on the other hand, is evident when a person is resting and feels relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and genitourinary systems. The role of the enteric nervous system is to manage every aspect of digestion, from the esophagus to the stomach, small intestine and colon.

There are three essential parts of the nervous system. These include the brain, the spine, and the nerves. The brain has three main parts that interact with the nervous system: the cerebrum, the cerebellum, and the medulla. Examples of the cerebrum's tasks include high-order thinking and learning, while the cerebellum manages learned automatic bodily functions, including walking, jumping, and running. The medulla processes simple body functions, such as breathing and digestion.

The spine is the area where reflexes are made. Split-second decisions do not go back to the brain and then back to the organ or body part. This would take too long and the nerve impulse would arrive too late to prevent the stimulus from becoming reality. For instance, if a ball was thrown at an individual's head, the reflex to move out of the way would come from the spine, not the brain, increasing reaction time. The spine is also the "highway" which passes orders from the brain to motor nerves.

There are four kinds of nerves- motor, sensory,afferentnerves and interneurons. Messages carried in all nerve types travel in only one direction.

Answer 3

If you place water in a bucket... The water makes the bucket wet and full to whatever extent you fill it, but the bucket doesn't MAKE the water or have anything to do with it other than to operate as a vessel to carry it...

It's up to you to fill or empty it.

The nervous system is like a highway that channels and categorizes stimuli and reacts accordingly.

Answer 4

There are areas at the base of the brain, called the limbic system, that appear to be associated with anxiety.

So yes.

Answer 5

No,it is a network of sense-conducting pathways. That hardly makes me nervous.

Answer 6

No it doesn't worry me at all.

Answer 7

rather operates & controls nervousness

Answer 8

no, that is my wife
