Papessa [141]

Answer:

My pretest behaviors were triggered by the sympathetic nervous system, while my body returned to its normal state by the way of the parasympathetic nervous system, after the test.

Explanation:

The sympathetic nervous system and the parasympathetic nervous system are part of the autonomic nervous system. The main function of the autonomic nervous system is to regulate the heart, kidneys, and liver which are not under voluntary control. The regulation of the body’s unconscious actions is executed through the sympathetic and the parasympathetic nervous system.

Upon exposure to stressors or threats, the sympathetic nervous system is triggered. Epinephrine and norepinephrine are then released, causing acceleration of the heart, constriction of blood vessels, increase in blood pressure, profuse sweating and other related responses against stress. The sympathetic nervous system controls all these involuntary responses that could be termed “fight-flight-or-freeze” response.

On the other hand, the parasympathetic nervous system initiates what is termed “rest and digest” response, which occurs immediately after the “fight-flight-or-freeze” phase response to stress is over. The body is returned to its normal state by the parasympathetic nervous system. The parasympathetic nervous system releases acetylcholine, which regulates the function of the body during a period of rest or recuperation.

Explain how the terms speed velocity and acceleration are related to each other
muminat
Acceleration is a little more complicated. It is defined as the rate of change of the object's velocity over its change in time. ... Or, if the acceleration is negative, it's called deceleration and describes something slowing down. For something to speed up or slow down, it has to have a certain change in velocity
