Stria terminalis – Wikipedia

Posted: December 9, 2018 at 9:42 pm

The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala, the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus Continue reading

The hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus is located below the thalamus and is part of the limbic system.[1] In the terminology of neuroanatomy, it forms the ventral part of the diencephalon. Continue reading

Hypothalamus, region of the brain lying below the thalamus and making up the floor of the third cerebral ventricle. The hypothalamus is an integral part of the brain. It is a small cone-shaped structure that projects downward from the brain, ending in the pituitary (infundibular) stalk, a tubular connection to the pituitary gland. Continue reading

Hypothalamus – New World Encyclopedia

Posted: November 9, 2018 at 5:42 am

The hypothalamus, also known as the "master gland," is a supervising center in the brain that links the body's two control systems, the nervous system and the endocrine system, via interaction with the pituitary gland (hypophysis). The hypothalamus (from Greek , "under the thalamus") is located below the thalamus, just above the brain stem, and occupies the major portion of the ventral region of the brain known as the diencephalon. The hypothalamus is found in all mammalian brains; in humans, it is roughly the size of an almond. The hypothalamus gland regulates certain metabolic processes and other autonomic activities; it is a control center for functions of the autonomic nervous system. As needed, the hypothalamus synthesizes and secretes neurohormones, often called "releasing hormones," that control the secretion of hormones from the anterior pituitary gland. The hypothalamus controls body temperature, hunger, thirst, blood pressure, heartbeat, carbohydrate and fat metabolism, and circadian cycles. Also, among other hormones, it releases gonadotropin releasing hormone (GnRH). The neurons that secrete GnRH are linked to the limbic system, which is primarily involved in the control of emotions and sexual activity. Specific functions are related to particular sections of the hypothalamus called nuclei. Although the hypothalamus is … Continue reading

Hypothalamus: The Body’s Thermostat | Ask A Biologist

Posted: at 5:42 am

All humans and many animals have a hypothalamus, found in the middle of the brain. Sweat gets a bad reputation, even though it plays an important role in cooling down our bodies when we get too hot. But how, exactly, does your body know when to start sweating? It knows because a part of your brain, called the hypothalamus, tells it to. All humans and many animals have a hypothalamus. The hypothalamus does many things, but two of its most important jobs are to maintain homeostasis and to control certain hormones. Homeostasis is very important to all animals, including humans. If we look at the word, we see that homeo means the same, and stasis means not moving, or holding. So homeostasis means that something is held at the same place. Lets think about homeostasis in terms of body temperature. Most animals maintain, or hold, their temperature at a certain level. For humans, this is about 98.6F (37C). When your hypothalamus senses that youre too hot, it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that youre too cold, it sends signals to your muscles that make your shiver and … Continue reading
