A person’s tear flow is a natural and important process. The healthy function of tear formation is of considerable importance not only for physical health, but also for mental health. What is tear flow? Tear flow is generally understood to be the formation of a mirror-like tear film that stretches protectively over the cornea of … Lacrimal Flow: Function, Tasks, Role & Diseases
The pineal gland is a small endocrine gland in the brain that mainly controls the circadian rhythm, or sleep-wake rhythm of the body via the hormone melatonin and serotonin in alternation. The pineal gland is of enormous importance because it not only controls many bodily functions depending on the time of day, but the hormonal … Pineal Gland: Structure, Function & Diseases
The parotid gland is paired and is the largest salivary gland in the human body. Topographically, the parotid gland is bounded by the external auditory canal and the mandible. The entire organ is encased in a layer of connective tissue called the parotid lobe. What is the parotid gland? The parotid gland is a purely … Parotid Gland: Structure, Function & Diseases

The ultrashort feedback mechanism is a regulatory circuit of endocrine secretion in autocrine and paracrine glands. In this feedback loop, a hormone inhibits its own secretion without intermediate steps or other hormones. Dysregulation in the ultra-feedback mechanism can result from diseases such as Graves’ disease. What is the ultrashort feedback mechanism? The regulatory circuit is … Ultrashort Feedback Mechanism: Function, Tasks, Role & Diseases
The milk-forming reflex, along with the milk ejection reflex, is one of the lactation reflexes that mammals use to nourish their offspring and are stimulated by direct contact with the offspring. For the lactation reflex, the hormone prolactin from the anterior lobe of the pituitary gland plays the main role. In the case of hormone … Lactic Reflex: Function, Tasks, Role & Diseases
As a complex system, the hormone system controls the coordination of the functions of all organs of the organism. In humans, over thirty different hormones (messenger substances) are responsible for this. The medical specialty of endocrinology deals with the disorders within the endocrine system. What is the endocrine system? The endocrine system includes both endocrine … Endocrine System: Structure, Function & Diseases
The long-feedback mechanism is a principle of feedback as it is relevant to hormone balance in the human body. Among the best-known long-feedback mechanisms is the regulatory loop between thyroid hormones and TSH (thyrotropin). Disturbances within this control loop occur in Graves’ disease, among others. What is the long-feedback mechanism? Among the best-known long-feedback mechanisms … Long-feedback Mechanism: Function, Tasks, Role & Diseases
Multiple endocrine neoplasia (MEN) is the collective term for various cancers – based on genetic defects – of endocrine glands, i.e. hormone-producing glands such as the pancreas, parathyroid gland and pituitary gland. Sustained therapy is usually only possible by complete removal of the corresponding gland. What is multiple endocrine neoplasia? Graphic illustration and infogram of … Multiple Endocrine Neoplasia: Causes, Symptoms & Treatment
