Vertigo and Dizziness - Overview
Vertigo and Dizziness are known to occur when there is a conflict between the signals that are sent to the brain by the balance as well as the position sensing systems of the body. The human brain is known to use the input from the sensory systems of our body – eyes, ears, skin, taste buds as well as smell in order to go out and maintain the sense of balance to the body as well as the orientation towards the surroundings.
Vision is the sensory organ that goes out to make us aware of our position in the environment as well as the motion in which we are existing. Vision emerges out to be an integral part of the body’s balance mechanism and therefore, often merges to over ride the information that is being provided to the other sensory systems of the body.
Sensory nerves, which are present all over the body, are the ones which allow us to keep a tab on the position of the legs, arms and the torso. Our body has an automatic mechanism, which makes it possible for us to make tiny changes in the posture and therefore maintain the balance of the entire body at the same time.
Skin pressure is known to give the sensory nerves the information regarding the position of the body as well as the motion that the body bears towards gravity at the same time.
A portion of our inner ear, which is better known by the name of labyrinth, is the ones which contain many semicircular canals. These are the ones which contain the specialized cells that are used by the body in order to detect the motion and change the position of the body at the same time. Also, in case of an injury to the inner ear or the infection of the same can send wrong signals to the brain and can lead to the occurrence of disruption in the balance mechanism of the body. These false signals are often the ones which can cause vertigo in most people.
