What hormones are produced by the adrenal medulla?

The adrenal medulla primarily produces stress hormones, notably adrenaline (epinephrine) and noradrenaline (norepinephrine), which are essential in preparing the body for a 'fight or flight' response during stressful situations. When the body perceives a threat, these hormones are released into the bloodstream, leading to physiological changes such as increased heart rate, heightened alertness, and enhanced energy availability. This rapid response system allows individuals to react swiftly in emergencies.

In contrast, growth hormones are produced by the pituitary gland and are involved in growth and development processes. Hormones regulating metabolism stem mainly from the thyroid gland and pancreas, playing crucial roles in how the body utilizes energy. Lastly, sex hormones, such as estrogen and testosterone, are primarily produced by the gonads (ovaries and testes) and are responsible for sexual development and reproductive functions. Each of these hormones plays distinct roles in the body, highlighting the specific function of the adrenal medulla's secretion of fight or flight hormones.
