Ways Through Which 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.

Thinking can influence the muscle nerves which leads to increase in activity. The muscles are usually made up of fibers which have a lot of capillaries which means when the blood supply is increased the muscles will expand. The expansion depends on the type of signal integrated by the brain. Too much blood supply to some organs may lead to pain due to the elasticity effect of capillaries.

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 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.
