What is the work of hypothalamus

Learning Objectives By the end of this section, you will be able to: • Explain the interrelationships of the anatomy and functions of the hypothalamus and the posterior and anterior lobes of the pituitary gland • Identify the two hormones released from the posterior pituitary, their target cells, and their principal actions • Identify the six hormones produced by the anterior lobe of the pituitary gland, their target cells, their principal actions, and their regulation by the hypothalamus The hypothalamus–pituitary complex can be thought of as the “command center” of the endocrine system. This complex secretes several hormones that directly produce responses in target tissues, as well as hormones that regulate the synthesis and secretion of hormones of other glands. In addition, the hypothalamus–pituitary complex coordinates the messages of the endocrine and nervous systems. In many cases, a stimulus received by the nervous system must pass through the hypothalamus–pituitary complex to be translated into hormones that can initiate a response. The hypothalamus is a structure of the diencephalon of the brain located anterior and inferior to the thalamus (Figure 1). It has both neural and endocrine functions, producing and secreting many hormones. In addition, the hypothalamus is anatomically and functionally related to the pituitary gland (or hypophysis), a bean-sized organ suspended from it by a stem called the infundibulum (or pituitary stalk). The pituitary gland is cradl...

The hypothalamus is a small area of the brain, located just above the brainstem. Its main function is to release several hormones to the pituitary gland, which stores and releases them into the bloodstream as necessary. The However, research does not suggest that a person should take supplements to boost hypothalamus and pituitary gland production. This article explores the role of the hypothalamus and pituitary gland and which nutrients may support their functioning. It also answers some common questions about the hypothalamus and pituitary gland. Share on Pinterest Eddy Zecchinon/EyeEm/Getty Images The hypothalamus and pituitary gland work together to secrete and distribute hormones that control various essential bodily functions. Hypothalamus The hypothalamus is a small area of the The hypothalamus receives signals from other areas of the brain and responds by secreting both releasing and inhibiting hormones. These hormones signal the pituitary gland to direct the functions of other glands, systems, and activities. These include: • • • reproductive organs • growth • • • fluid balance • • milk production The hypothalamus maintains homeostasis by receiving signals sent by different areas of the body, which carry messages about elements that require balancing or other actions. The hypothalamus responds by releasing the required hormones to the pituitary gland, which then releases them into the bloodstream. These hormones then direct the body to perform actions to achieve h...

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...
