Ways 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 cardiovascular framework which is in charge of the pumping of blood to all body parts is bolstered with various nerves. The impacts of adrenergic hormones are so articulated in this organ. The cardiovascular nerves will guide the diastolic and systolic volumes of blood. The results may lead to increased pumping in order to meet the demands. The level of responsiveness of this organ depends on the type of hormone involved.

Excitements or fear leads to the release of hormones by the sympathetic nervous system which excites the muscles and heart among other organs. This means a lot of blood will be directed to such organs. The respiratory system has the obligation to ensure enough oxygen is taken in for rapid oxygenation. It will have to increase the respiratory rate in order to meet the demand.

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.
