The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.

The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.

How the seismic tracings recorded at station A and station B indicate that station A is farther from the earthquake epicenter th
VMariaS [17]

The seismic traces recorded at station A and station B indicate that station A is further from the earthquake epicenter than station B because the ground movement detected at B was greater than that detected at A, with seismic waves more frequent and less frequent respectively.

<h3>Seismograph</h3>

A seismograph is a device that detects ground movements, including those generated by seismic waves. It consists of the basic sensor of the seismographic instruments of which the seismograph and the seismoscope are part. These movements are then recorded in seismographs, which have been plotted graphs called seismographs.

<h3> Propagation speed</h3>

Seismic station A is located 5,400 kilometers from the earthquake's epicenter. How long would it take for the first S wave produced by this earthquake to reach seismic station A? The propagation speed of this type of waves varies with the medium in which they propagate, with typical values ​​of

  • 330 m/s in air
  • 1 450 m/s in water
  • and 5 000 m/s in granite.

They are not as destructive as S waves or the surface waves that follow them. The propagation speed of these waves is, in general, slightly less than twice that of S waves.

With this information, we can conclude the velocity of propagation of seismic waves and how a seismograph enumerates the distance from the epicenter of an earthquake.
