Mechanisms Through Which Thoughts Influence Nerves

By Sandra Reynolds


The brain is the central point of the nervous system which receives signals from different sense organs then integrates and make decisions as per the type of signal received. Every thought be it a danger, image or sound will make the brain to generate the appropriate response which will be sent through the nerve to the respective organ. This article will look at how different types of thoughts influence the nerves in various parts of a body. This article highlights more on thoughts influence nerves.

Considerations can impact the optic nerve which implies the sight might be expanded or diminished. On the off chance that one sees risk the signal will be sent through the optic nerve right into the nervous system. The feedback from the brain will result in the general sharpness of the sight which will help one to escape the danger by making clear and accurate visual judgments.

When someone is scared a lot of adrenaline is released into the blood. Most of which will be transported by the blood vessels to the muscles since this is the most common part of the body engaged in fighting. The ultimate result is that the muscles will receive a large supply of blood which will make them increase in size a phenomenon called muscle tension. Prolonged tension can cause a lot of pain

The cardiovascular system which is responsible for the pumping of blood to various parts of a body is fed with different nerves. The effects of the flight and fight hormones are so pronounced in this organ. The cardiac nerves will direct the heart to increase systolic pressure. This means the amount of blood being pumped will increase of which if it happens so fast the one may feel pain around chest cavity.

In most instances, one tends to breath faster and deeper when they think of something or someone. This is because the thoughts trigger certain signals which lead to the production of hormones to combat to control the situation. Some of this hormones lead to reactions that activate other parts of a body, therefore, more oxygen is needed to meet the increased blood supply to the respective organs.

In most cases, the effects of a psychological response are witnessed courtesy of a skin. The skin is one of the largest organs that is known for its protection and cooling mechanism. For instance, during excitements, a lot of neurological changes that affect major organs results in rising in temperature. The skin will have to engage the adrenal glands to release sweats which will cool the body.

The brain is innervated by very small and delicate blood vessels. The fact that it works to resolve the problems experienced in different parts of the body does not mean it is not affected itself. Repeated episodes of thoughts, for instance, the stress can lead to damage to this delicate vessel leading to leakage which clots and block the supply of oxygen to brain cells.

The brain also controls the exocrine glands that are associated with the digestive system. When one feels hungry the signal will be sent from the hypothalamus which will command this gland to generate the appropriate hormone that is responsible for food absorption. The negative state of mind as well will undermine the production of these hormones leading to poor appetite.
