Examples include the Development [ ] Main article: Local chemical messengers, not generally considered part of the endocrine system, include The ability of a target cell to respond to a hormone depends on the presence of receptors, within the cell or on its plasma membrane, to which the hormone can bind. Hormone receptors are dynamic structures. Changes in the number and sensitivity of hormone receptors may occur in response to high or low levels of stimulating hormones. Blood levels of hormones reflect a balance between Hormone half-life and duration of activity are limited and vary from hormone to horm...

For example, seaweed, which is rich in This knowledge led to an

Overview Your pineal gland is a tiny endocrine gland in your brain that releases the hormone melatonin. What is the pineal gland? Your pineal gland, also called the pineal body or epiphysis cerebri, is a tiny gland in your brain that’s located beneath the back part of the corpus callosum. It’s a part of your endocrine system and secretes the hormone melatonin. Your pineal gland’s main job is to help control the circadian cycle of sleep and wakefulness by secreting melatonin. The pineal gland is shaped like a tiny pinecone, which is how it got its name (“pine”-al gland). However, it is pronounced “pin-ee-uhl.” The pineal gland is the least understood gland of the endocrine system, and it was the last part of the endocrine system to be discovered. What is the endocrine system? Your endocrine system is a network of several glands that create and secrete (release) hormones. A gland is an organ that makes one or more substances, like hormones, digestive juices, sweat or tears. Endocrine glands release hormones directly into your bloodstream. Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. The following organs and glands make up your endocrine system: • Hypothalamus. • • • Parathyroid glands. • Adrenal glands. • Pineal gland. • • Ovaries. • Testes. What is melatonin? Melatonin is a hormone that’s mainly produc...

Overview Galactorrhea (guh-lack-toe-REE-uh) is a milky nipple discharge unrelated to the normal milk production of breast-feeding. Galactorrhea itself isn't a disease, but it could be a sign of an underlying problem. It usually occurs in women, even those who have never had children or after menopause. But galactorrhea can happen in men and even in infants. Excessive breast stimulation, medication side effects or disorders of the pituitary gland all may contribute to galactorrhea. Often, galactorrhea results from increased levels of prolactin, the hormone that stimulates milk production. Sometimes, the cause of galactorrhea can't be determined. The condition may resolve on its own. Symptoms Signs and symptoms associated with galactorrhea include: • Persistent or intermittent milky nipple discharge • Nipple discharge involving multiple milk ducts • Spontaneously leaked or manually expressed nipple discharge • One or both breasts affected • Absent or irregular menstrual periods • Headaches or vision problems When to see a doctor If you have a persistent, spontaneous milky nipple discharge from one or both of your breasts and you're not pregnant or breast-feeding, make an appointment to see your doctor. If breast stimulation — such as excessive nipple manipulation during sexual activity — triggers nipple discharge from multiple ducts, you have little cause for worry. The discharge probably doesn't signal anything abnormal, and this discharge often resolves on its own. If you ...

Definition Endocrine glands are tissues or organs that excrete chemical substances (hormones) directly into the blood. Common endocrine glands are the hypothalamus, pineal, and adrenal glands. Endocrine glands secrete hormones directly into the bloodstream or into the intercellular space, allowing the hormones to reach their target. Overview Endocrine system glands are spaced throughout the entire body. They release a wide number of hormones which control the metabolism and function of other cells. While in the bloodstream, the hormones are able to travel through the body’s Endocrine Glands Diagram As you can see in the image above, men and women share all of the same endocrine glands, besides the reproductive organs. While reproductive organs have the primary function of creating and releasing Examples of Endocrine Glands Pineal Gland The pineal gland is a small gland located within the brain that serves as a great example of endocrine glands in general. The pineal gland is activated by neurons connected to your eyes. When these nerves are activated by light, the pineal gland is repressed. When nighttime comes, and the light reaching your eyes decreases, the pineal gland becomes activated. The Thyroid Gland The Thyroid hormones can increase the rate of your cellular metabolism, or decrease it. These activities are in part directed by another endocrine gland, the pituitary, which signals to the thyroid which hormones to release. In turn, your metabolism is regulated. In fa...

Hint: Hormones are certain chemicals secreted in the body. It is released in trace amounts, and they act as intracellular messengers. They are transported to different tissues and organs via blood since they don’t require ducts to translocate them in the body. Complete step by step answer: Hormones are secretions of the endocrine glands directly secreted into the bloodstream, and they are translocated to the target site. There are many endocrine glands located in the body at different locations: They are; 1) Pituitary gland: It is found below the hypothalamus and it is attached to it with a stalk. It secretes several hormones like growth hormones, prolactin, oxytocin, vasopressin, etc. 2) Pineal gland: it secretes melatonin which helps to maintain the sleep-wake cycle, and also regulates body temperature. 3) Thyroid gland: it secretes thyroxine which helps in maintaining the basal metabolic rate, body temperature, body weight, etc. 4) Adrenal glands: Adrenaline and noradrenaline are secreted by this gland which helps in an emergency situation, and hence it is called the flight or fight hormone. 5) Testes: it is present in males that secrete male sex hormones, such as testosterone; which is responsible for the secondary sexual characters in males like deepening of the voice, the appearance of the beard and moustache. 6) Ovary: it is present in females that secrete female sex hormones. It is responsible for secondary sexual characters in the female like starting of the menst...
