What is a vasomotor center?

The vasomotor center is a group of sympathetic nerve cells contained in Medulle Oblongata, the structure of the brain stem. The vasomotor center regulated involuntarily without the conscious effort of the autonomous nervous system (ANS) is responsible for the vital vegetative functioning of the human body, namely blood pressure, breathing and heart rate. In particular, the ASS function allows the peripheral nervous system obligation to control tasks that take place elsewhere in the body different from the brain and spinal cord. Vasomotor imbalance can cause shock, failure of ANS and even death. Medulla is located in the middle of the brain stem, it works primarily as an internal switchboard, transfers information to the brain and from the brain. Communication occurs through a network of neurons together described as a reticular formation, an altak known as the reticular activation system (races), in discussion on samples of excitement and sleep. While the parasympathetic component actually regulates vital surgery for survival, sympathetic activitiesThey use those to adapt stress. For example, if fear is experienced, some physiological requirements will require a "flight or struggle" response to launch an action from a parasympathetic nervous system.

Blood pressure regulation and heart rate mechanisms are possible due to biroreceptors, nerve fibers in blood vessels sensitive to the activity of the sympathetic nervous system. Increasing blood pressure triggers biroreceptors to send information to the vasomotor center, which in turn reduces the pressure to maintain homeostasis. Pervisy is limited during the period of increased sympathetic functioning and dilatation, from which any of which has a direct effect on heart rate, which will reduce it when the vasomotor center is inhibited and increases the rhythm after stimulation.

Some people experience disorders of the vassomotor center causing hypotension, loss of vasomotor tone and general autonomous imbalancehu or failure. The hypotension is indicated by reading 90 millimeters of mercury (mmHg) over 60 mm or less, is a condition of low blood pressure, which is manifested by fainting, dizziness, nausea and fatigue. When blood pressure is too low, circulation is inefficient, which is the result of reduced vasomotor tone. Dysautonomy concerns the failure or imbalance of ANS caused by damage or certain diseases, including diabetes and epilepsy. Parkinson's, Postural Tachycardia (Pots), Mitral Valla prolapse, and multiple systems (MSAs) are primary ANS disorders affecting many people in the United States since 2011.
