An Overview On Thoughts Influence Nerves

By Sandra Reynolds


The brain controls the body functioning by sending and receiving the electrical signals from various parts of a body. The type of signal will determine the type of change required. Well, it is not always the physical stimuli that effect this changes but even the psychological imagination are capable of causing stimulating the nerve impulse. It is critical to know how thoughts influence nerves for easy interpretation of body changes.

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 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 cerebrum is innervated by little and sensitive veins. Some of the thought that results in high blood pressure are a treat to this veins. Repeated episodes of this pressure may eventually lead to breakdown of the vessels. Once this happens the brain cells will not get the oxygen and they may die. This is very risky and can result in other complications such as stroke.

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.
