päärauhaset
Päärauhaset, often translated as "head glands" or "cranial glands" in English, refers to a group of endocrine glands located within the head. These glands play crucial roles in regulating various bodily functions through the production and secretion of hormones. The most prominent of these glands include the pituitary gland and the pineal gland. The pituitary gland, situated at the base of the brain, is often called the "master gland" because it controls the activity of many other endocrine glands. It secretes hormones that influence growth, metabolism, reproduction, and stress response. The pineal gland, located deep within the brain, is primarily responsible for producing melatonin, a hormone that regulates sleep-wake cycles. Collectively, these glands are essential for maintaining homeostasis and ensuring the proper functioning of the entire organism. Their intricate interplay with the nervous system highlights the complex regulatory mechanisms governing the human body. Disruptions in the function of these head glands can lead to a variety of hormonal imbalances and associated health conditions.
