Mechanisms 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.

Some of the nerves that are influenced by hormones include the sensory nerves. Perhaps this is why the eye pupil increase when one look at a strange image. This dilation will increase the sight and enable one to make a better judgment in the process. Actually, the eye is made up of blood capillaries which dilate as a result of hormonal change.

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 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.

It is critical to note that the psychology of a person affects his or her eating habits both negatively and positively depending on what one thinks about. If it is stress it will have a negative impact on digestion. In fact, it used to be associated with stomach ulcers because it is believed to cause trickling of lots of stomach acids. However, thinking of eating increase the cravings which may lift the eating psyche.
