Answer to Question 1

True

Answer to Question 2

The body responds to stress by activating the fight-or-flight mechanism, which prepares a person to take action by stimulating the vital defense systems. This stimulation originates in the hypothalamus and the pituitary gland in the brain. The hypothalamus activates the sympathetic nervous system, and the pituitary activates the release of catecholamines (hormones) from the adrenal glands.
These hormonal changes increase heart rate, blood pressure, blood flow to active muscles and the brain, glucose levels, oxygen consumption, and strength-all necessary for the body to fight or flee. For the body to relax, one of these actions must take place. However, if the person is unable to take action, the muscles tense up and tighten. This increased tension and tightening can be dissipated effectively through some coping techniques.
