As he slowly gets up to investigate, his heart begins to race, his mouth is dry, and he begins to sweat; his "sympathetic nervous system" has been activated.

The sympathetic nervous system (SNS) is a piece of the autonomic nervous system (ANS), which likewise incorporates the parasympathetic nervous system (PNS).  

The sympathetic nervous system ordinarily capacities to create restricted alterations, (for example, perspiring as a reaction to an expansion in temperature) and reflex modifications of the cardiovascular framework. Under states of pressure, be that as it may, the whole thoughtful sensory system is enacted, delivering a prompt, boundless reaction called the fight or-flight reaction.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
