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.

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 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 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.

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.
