GENERAL HISTOLOGY

Detailed explanation-1: -Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or harmful in a fight-or-flight situation.

Detailed explanation-2: -Cortisol is a steroid hormone that is produced by your 2 adrenal glands, which sit on top of each kidney. When you are stressed, increased cortisol is released into your bloodstream.

Detailed explanation-3: -Stress causes the body to release the hormone cortisol, which is produced by the adrenal glands. Cortisol is important to blood pressure regulation and the normal functioning of several body systems including cardiovascular, circulatory, and male reproduction.

Detailed explanation-4: -Average cortisol level was found to increase approximately 9 times in stressful periods compared with that in relaxed periods. STAI, which shows state anxiety, showed an increase supporting this increase.

Detailed explanation-5: -In humans, the peak level secretion occurs in the morning (07:00–08:00 a.m.), which is considered the active phase, while its lowest secretion is around 02:00–04:00 a.m. at night [44, 47].
