The hypothalamus, a small structure located inferior to the thalamus, secretes stimulatory and inhibitory factors that regulate the action of hormones produced in the anterior pituitary: growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin (PRL)
The hypothalamus (from Ancient Greek ὑπό, under, and θάλαμος, chamber) 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
The neurohypophysis contains long axons of neurosecretory neurons surrounded by supporting cells. The cell bodies of these axons lie in the part of the brain called the hypothalamus. The hypothalamus forms the floor and lower walls of the brain (see Figure 1.9) and contains a fluid-filled cavity, the third ventricle. This ventricle is continuous with the other ventricles in the brain and also with the central canal of the spinal cord
Hypophysis or the pituitary gland of human is small pea-shaped gland weighing about 0.5 gm which makes up 80 percent of the gland's overall weight. It is located under the brain, just behind the bridge of the nose between the hypothalamus and the pineal gland. It is enclosed within a small bony cavity, the sella turcica, of the sphenoid bone
The hypothalamic-pituitary-adrenal axis is a complex set of direct influences and feedback interactions among three components: the hypothalamus, the pituitary gland, and the adrenal glands. These organs and their interactions constitute the HPA axis, a major neuroendocrine system that controls reactions to stress and regulates many body processes, including digestion, the immune system, mood and emotions, sexuality, and energy storage and expenditure. It is the common mechanism for.
The hypothalamus and pituitary gland are connected at the base of the brain, and are responsible for the regulation of hormones associated with growth and bone renewal. Certain factors produced by the hypothalamus are secreted and travel along the pituitary stalk, which then promotes the secretion of various pituitary hormones

L'hypothalamus (du grec : ὑπό, hypo = dessous et θάλαμος, thálamos = chambre, cavité) est une structure du système nerveux central, située sur la face ventrale de l'encéphale.Cette partie du cerveau est constituée de plusieurs sous-structures, appelées noyaux. Ces noyaux sont des ensembles anatomiquement indépendants de neurones qui assurent diverses fonctions
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),. FUNCTION• The most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland.• It synthesizes and secretes certain neurohormones, often called hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones. 6 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 . Figure 2
The pituitary gland, also known as the hypophysis, is a roundish organ that lies immediately beneath the hypothalamus, resting in a depression of the base of the skull called the sella turcica (Turkish saddle). In an adult human or sheep, the pituitary is roughly the size and shape of a garbonzo bean The hypothalamic level of regulation is neurohormonal. Collections of neuronal cell bodies (called nuclei) reside in several regions of the hypothalamus and are collectively referred to as the hypophysiotropic (i.e., stimulatory to the hypophysis [= pituitary]) region of the hypothalamus The pituitary or hypophysis is situated below the hypothalamus within a depression of the sphenoid bone called the sella turcica.

Hypothalamic-Pituitary-Ovarian Axis. The hypothalamic-pituitary-ovarian axis secretes hormones involved in reproduction. There are three main components. Hypothalamus: located at the base of the brain, just above the brainstem.Along with homeostasis, the hypothalamus also secretes certain hormones, including gonadotropin-releasing hormone (GnRH)
The hypothalamus, located just below the Thalamus and the 3rd ventricle, is controlling everything involved with the pituitary gland. The hypothalamus is linked to the pituitary gland by both nerve fiber tracts and a profuse network of capillaries called the hypothalamic-pituitary portal system (aka hypophyseal portal system).. Look at the pathway of the blood in the picture below: On the.
The hypothalamus occupies the side walls and floor of the third ventricle. It is a bilateral, paired structure. Despite its small size—it weighs only 4 g—it has major functions in homeostasis and survival. Its homeostatic functions include control of body temperature and circulation of blood

Hypothalamohypophyseal tract The hypothalamohypophyseal tract is a bundle of axons that connects the hypothalamic nuclei with the neurohypophysis. Its function is to carry the two hypothalamic neurohormones oxytocin and antidiuretic hormone to the neurohypophysis, where they are stored and released upon the body's needs
