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 →

The hypothalamus is a brain structure made up of distinct nuclei as well as less anatomically distinct areas. It is found in all vertebrate nervous systems. In mammals, magnocellular neurosecretory cells in the paraventricular nucleus and the supraoptic nucleus of the hypothalamus produce neurohypophysial hormones, oxytocin and vasopressin Continue reading →

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, 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. Continue reading →

The thalamus (from Greek , "chamber")[1] is a large mass of gray matter in the dorsal part of the diencephalon of the brain with several functions such as relaying of sensory signals, including motor signals, to the cerebral cortex,[2][3][pageneeded] and the regulation of consciousness, sleep, and alertness.[4] It is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain. It is the main product of the embryonic diencephalon, as first assigned by Wilhelm His, Sr. in 1893.[5] The thalamus is a paired structure of gray matter located in the forebrain which is superior to the midbrain, near the center of the brain, with nerve fibers projecting out to the cerebral cortex in all directions. The medial surface of the thalamus constitutes the upper part of the lateral wall of the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic adhesion. The lateral part of the thalamus is the phylogenetically newest part of the thalamus (neothalamus), and includes the lateral nuclei, the pulvinar and the medial and lateral geniculate nuclei.[6][7] There are areas of white matter in the thalamus including the … Continue reading →

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 →
