What is the function of hypothalamus class 10

How Does the Brain Work? And How Does the Nervous System Work? How do you remember the way to your friend's house? Why do your eyes blink without you ever thinking about it? Where do dreams come from? Your brain is in charge of these things and a lot more. In fact, your brain is the boss of your body. It runs the show and controls just about everything you do, even when you're asleep. Not bad for something that looks like a big gray wrinkly sponge. What Are the Parts of the Brain? Your brain has many different parts that work together. We're going to talk about these five parts, which are key players on the brain team: • cerebrum (say: suh-REE-brum) • cerebellum (say: sair-uh-BELL-um) • brain stem • pituitary (say: puh-TOO-uh-ter-ee) gland • hypothalamus (say: hy-po-THAL-uh-mus) What's the Cerebrum? The biggest part of the brain is the cerebrum. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. So you need your cerebrum to dance or kick a soccer ball. You need your cerebrum to solve math problems, figure out a video game, and draw a picture. Your memory lives in the cerebrum — both short-term memory (what you ate for dinner last night) and long-term memory (the name of that roller-coaster you rode on two summers ago). The cerebrum also helps you reason, like when you figure out that you'd better do your homework now because your mom is taking you to a movie later. The cerebrum has two halves, w...

It produces hormones in a different part of the brain referred to as the pituitary gland that passes hormones to different structures. The hypothalamus forms a part of the limbic system – a part of the brain which includes the amygdala, thalamus, cingulate gyrus and hippocampus. The limbic system in all the higher vertebrates is well-developed and is involved in activities like olfaction, emotional responses, long-term memory, acquiring new skills and is involved in different behavioral responses. The hypothalamus is the site of thermoregulation regulating the temperature of the body and participates in regulating blood pressure, water balance and sensing hunger and thirst. There is a direct connection between the hypothalamus and the pituitary gland through a thin stalk referred to as the infundibulum. Several actions that are raised by the hypothalamus are communicated via secretions that are produced by the pituitary gland, found underneath. Location of Hypothalamus – Hypothalamus Function The hypothalamus is found at the...

The hypothalamus is an important part of your brain that controls lots of your basic bodily functions. Some hypothalamus disorders lead to hormone and weight problems. What Is the Hypothalamus? The • • Thyroid • Ovaries • Testicles ‌ Your hormone system operates in a feedback loop that signals the hypothalamus to release more hormones or to stop releasing them. ‌ The hypothalamus controls many different functions. It's important for your sex drive, behaviors, and emotions. Other functions include: • Hunger • Thirst • Weight • Body temperature • Breast milk production • Salt and water balance • Circadian rhythm, or your sleep-wake cycle • Childbirth Hypothalamus Disorders Sometimes there are problems with your hypothalamus that can cause diseases. These problems can also affect your pituitary gland. Some disorders lead to not enough or too many hormones. Hypothalamus disorders include:‌ Hypothalamic obesity. Injury to the hypothalamus can cause problems with hunger. People who have hypothalamic obesity can have symptoms like: • Fast weight gain • Excessive weight gain • Uncontrollable appetite • Low metabolism‌ Functional hypothalamic amenorrhea. This condition is sometimes called secondary amenorrhea and happens when you stop having your period.‌ When your body doesn’t have enough energy from food, it can cause you to have high cortisol levels. The cortisol dampens your hypothalamus-ovary connection, which means you'll have low amounts of hormones. This affects ovulation a...

The hypothalamus is a small structure in the brain. It is located at the center of the base of the brain, near the pituitary gland, and is about the size of a walnut. The hypothalamus is important in regulating hormone levels in the body. It also plays a role in regulating many body systems including the sleep/wake cycle, body temperature, and weight. ttsz / Getty Images How It Works When the body experiences some kind of stress, the HPA axis may get activated. It sets off a series of events in the body in response. Stress can mean not only emotional stress but also being scared or nervous. The HPA axis gets the message and goes to work in seconds. For that reason, the cortisol produced by the stress response also turns around and acts upon the hypothalamus and the pituitary gland. It connects with receptors on the hypothalamus. This causes the HPA axis to slow down and stop the production of corticotropin-releasing and adrenocorticotropic hormones. Summary The hypothalamic-pituitary-adrenal (HPA) axis involves the central nervous system and the endocrine system adjusting the balance of hormones in response to stress. Stress results in the hypothalamus stimulating the pituitary gland to release hormones that further cause the adrenal glands to release cortisol. Cortisol prepares the body for "fight or flight." High levels of cortisol signal the hypothalamus that it no longer needs to stimulate the pituitary gland to raise levels further. Long periods of stress leading to c...

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...

What is Hypothalamus? Hypothalamus is a minute region, almost the size of an almond, present at the centre of the human brain, near the pituitary gland. It consists of three main regions: • The anterior region. • The middle region. • The posterior region. It plays a vital role in the production of hormones. Maintaining the hypothalamus health is very important. Its improper functioning causes several disorders. Also Refer:Â Structure of Hypothalamus The structure of hypothalamus is made up of three main regions: • Anterior region • Middle region • Posterior region Anterior Region • The anterior region is also known as the supraoptic region. • It regulates body temperature and maintains the circadian rhythm. • There are several small nuclei in the hypothalamus. The major hypothalamic nuclei include supraoptic and paraventricular nuclei. • The nuclei in this region are involved in the hormone secretion. Following are the hormones secreted by the anterior region of the hypothalamus: • Corticotropin-releasing hormone • Thyrotropin-releasing hormone • Gonadotropin-releasing hormone • Oxytocin • Vasopressin • Somatostatin Middle Region • This is known as the tuberal region. • It consists of ventromedial and arcuate nuclei. • The ventromedial nuclei control the appetite, whereas the arcuate nuclei secrete the growth hormone responsible for the growth and development of the body. Posterior Region • This region is also known as the mammillary region. • The major nuclei include post...
