Vasopressin hormone function

Your hypothalamus, a structure deep in your brain, acts as your body’s smart control coordinating center. Its main function is to keep your body in a stable state called homeostasis. It does its job by directly influencing your autonomic nervous system or by managing hormones. Many conditions can damage your hypothalamus, which can affect many bodily functions. Function The hypothalamus helps manage your body temperature, hunger and thirst, mood, sex drive, blood pressure and sleep. What is the hypothalamus? The hypothalamus is a structure deep within your brain. It’s the main link between your What does your hypothalamus do? Your hypothalamus receives chemical messages from nerve cells in your brain and from nerve cells in your body (your peripheral nervous system), which is also responding to signals outside your body. Your hypothalamus’s main function is to react to these messages to keep your body in a stable state or internal balance. Just like you may have a “smart control” system to seamlessly manage all functions in your home, your hypothalamus is your body’s “smart control” coordinating center. Your hypothalamus helps manage your: • Body temperature. • • Hunger and thirst. • Sense of fullness when eating. • Mood. • Sex drive. • Your hypothalamus performs many of its “body balancing” jobs either by directly influencing the autonomic nervous system or by managing hormones. Your autonomic nervous system (bodily functions that work automatically) control several impor...

So Now, the brain has two interconnected structures: the The When ADH is produced, it travels down the axons of these neurons, and these axons have small dilations called Herring bodies, which is where ADH is stored.

The hypothalamus produces and secretes not only neurotransmitters and neuropeptides but also several neurohormones that alter anterior pituitary gland function and two hormones, vasopressin ( secretory granules that are then carried through the axons and stored in nerve terminals located in the median eminence or posterior pituitary gland. In response to neural stimuli, the contents of the secretory granules are extruded from the nerve terminals into a capillary network. In the case of hormones that affect pituitary function, the contents of the secretory granules are carried through the hypophyseal-portal circulation and are delivered directly into the anterior pituitary gland.

These hypothalamic neurohormones are known as releasing hormones because their major function is to stimulate the secretion of hormones originating in the anterior pituitary gland. For example, certain releasing hormones secreted from the hypothalamus trigger the release from the anterior pituitary of substances such as A classic model for neurohormonal activity is the posterior lobe of the pituitary gland (neurohypophysis). Its secretory products, vasopressin and oxytocin, are produced and packaged into neurosecretory granules in specific groups of nerve cells in the hypothalamus (the supraoptic nuclei and the paraventricular nuclei). The granules are carried through the axons that extend through the infundibular stalk and...

What are hormones? Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, Scientists have identified over 50 hormones in the human body so far. Hormones and most of the tissues (mainly glands) that create and release them make up your • • Homeostasis (constant internal balance), such as • Growth and development. • Sexual function. • Reproduction. • Sleep-wake cycle. • Mood. With hormones, a little bit goes a long way. Because of this, minor changes in levels can cause significant changes to your body and lead to certain conditions that require medical treatment. What do hormones do? Hormones are chemical messengers that affect and manage hundreds of bodily processes. Often, a bodily process involves a chain reaction of several different hormones. A hormone will only act on a part of your body if it “fits” — if the cells in the target tissue have receptors that receive the message of the hormone. Think of a hormone as a key and the cells of its target tissue, such as an organ or fat tissue, as specially shaped locks. If the hormone fits the lock (receptor) on the cell wall, then it’ll work; the hormone will deliver a message that causes the target site to take a specific action. Your body uses hormones for two types of communication. The first type is communication between two endocrine glands: One gland releases a hormone, which stimulates another gland to change the levels of hormones that it’s relea...
