Hormonal control refers to the regulation of various bodily functions through hormones, which are chemical messengers produced by glands in the endocrine system. These hormones travel through the bloodstream to target organs, influencing processes such as growth, metabolism, and mood. Key glands involved include the pituitary gland, thyroid gland, and adrenal glands. The balance of hormones is crucial for maintaining homeostasis, or the body's stable internal environment. Disruptions in hormonal levels can lead to various health issues, such as diabetes, thyroid disorders, and mood disorders. Understanding hormonal control helps in diagnosing and treating these conditions effectively.
