A. Competing in an athletic event
B. First day of college after X
C. Falling asleep during a lecture
D. Taking a test while unprepared

Answer 1

Adrenaline is also known as epinephrine. The hormone adrenaline or epinephrine is released by the adrenal gland and medulla oblongata. It is an amino-acid hormone.

Complete answer:
The endocrine system consists of hormone-forming glasses. The signals that are secreted and transported to the particular region by the exocrine glands through the blood are referred to as hormones. Hormones can be categorized as steroids, eicosanoids, or proteins. Both behavioral and physiological activities are regulated by hormones. They contain information and instructions from one cell to the next. During the endangered situation, the epinephrine or adrenaline begins releasing epinephrine that causes blood sugar levels to rise, cardiac rate, and pupil dilations. It acts as a neurotransmitter. This chemical messenger is called a neurotransmitter which transports messages through the synapse from the nerve cell to the target organ. Normally both adrenal and some nerves contain epinephrine. Increasing blood flow to the muscles, the heart output, pupil dilation, and blood sugar plays an important role in the combat-and-flight response. The hormonal factor involves epinephrine release, which is an adrenomedullary reaction in response to stress and regulated by the sympathetic nervous system. In relation to epinephrine, the main emotion studied is fear.
Therefore, Choice C is the right answer.

Note: Physiological symptoms such as assault, sudden panic reactions to a certain degree, called battle or flight response or acute stress or hyper acoustic stress, and the response is referred to as a reflex action. The adrenaline hormone is released in this situation and keeps the body cool.
