In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables. For example, in.
Vasovagal syncope is a common cause of fainting. The vagus nerve is overstimulated and causes the body's blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward to the brain against gravity. Without blood flow, the brain turns off.
Syncope, also known as fainting, is a sudden, short loss of consciousness that usually causes the body to go limp. This is often associated with a limited supply of oxygen-rich blood to the brain and low blood pressure (hypotension). When fainting occurs, the body goes limp and is unresponsive to outside stimulation.
