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.

Thoughts can influence the optic nerve which means the sight may be increased or decreased. If one sees the danger the signal will be sent to the brain through the optic nerve. The signal from the brain will lead to the dilation of the pupil in order to increase the sight. The blood supply to an eye will be increased which means the sight will also increase.

When somebody is frightened a great deal of adrenaline is discharged into circulation. The vast majority of which will be transported by the veins to the muscles considering they are associated with lifting and battling. A definitive outcome is that the muscles will get substantial blood supply which will trigger expansion. The expansion and contraction of muscle fibers resulting in trembling.

The heart is the major organ that is involved in distributing blood to various part of a body. The level of pumping is controlled by the autonomic nervous system. Depending on the type of thought the brain can command the heart to increase the amount pumped to a particular part of a body. Once the signal dissipates the parasympathetic nerve will rely on a signal that cools down the heart to normal.

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.

Perhaps one may wonder why they find themselves sweating when they are depressed. Ideally, the central nervous system will send out effector mechanisms to different organs and the muscles, heart and the respiratory system becomes activated the general body temperature will increase. The body will have to produce sweat as a coping mechanism.

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.

Thought can as well influence the digestive system in so many ways. When one thinks of food his or her brain is able to release enteric hormones that increase the appetite for food. Some thoughts can as well have a negative impact on the digestion such that the appetite is lost and one is not able to eat which means the level of energy may decrease.
