Anterior pituitary18

• A major organ of the endocrine system, the anterior pituitary (also called the adenohypophysis or pars anterior) is the glandular, anterior lobe that together with the posterior lobe (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis). (wikipedia.org)
• Proper functioning of the anterior pituitary and of the organs it regulates can often be ascertained via blood tests that measure hormone levels. (wikipedia.org)
• as a result, it is often considered part of the anterior pituitary. (wikipedia.org)
• In all animals, the fleshy, glandular anterior pituitary is distinct from the neural composition of the posterior pituitary. (wikipedia.org)
• citation needed] The anterior pituitary is composed of three regions: Pars distalis The pars distalis (distal part) comprises the majority of the anterior pituitary and is where the bulk of pituitary hormone production occurs. (wikipedia.org)
• These cells all together produce hormones of the anterior pituitary and release them into the blood stream. (wikipedia.org)
• Microanatomy of the pars distalis showing chromophobes, basophils, and acidophils Eosinophilic follicles are a common normal finding in the anterior pituitary. (wikipedia.org)
• The anterior pituitary is derived from the ectoderm, more specifically from that of Rathke's pouch, part of the developing hard palate in the embryo. (wikipedia.org)
• The pouch eventually loses its connection with the pharynx, giving rise to the anterior pituitary. (wikipedia.org)
• The posterior wall of the anterior pituitary forms the pars intermedia. (wikipedia.org)
• Hormone secretion from the anterior pituitary gland is regulated by hormones secreted by the hypothalamus. (wikipedia.org)
• At this site, these cells can release substances into small blood vessels that travel directly to the anterior pituitary gland (the hypothalamo-hypophyseal portal vessels). (wikipedia.org)
• Aside from hypothalamic control of the anterior pituitary, other systems in the body have been shown to regulate the anterior pituitary's function. (wikipedia.org)
• Hypophyseal Portal System: The system of blood vessels that link the hypothalamus and the anterior pituitary in the brain. (sabkuchonline.pk)

Posterior pituitary12

• The pituitary stalk connects the hypothalamus to the posterior pituitary. (wikipedia.org)
• Pars intermedia The pars intermedia (intermediate part) sits between the pars distalis and the posterior pituitary, forming the boundary between the anterior and posterior pituitaries. (wikipedia.org)
• Its formation from the soft tissues of the upper palate contrasts with the posterior pituitary, which originates from neuroectoderm. (wikipedia.org)
• The hormones are stored in neurosecretory vesicles (Herring bodies) before being released by the posterior pituitary into the bloodstream. (sabkuchonline.pk)
• Two hormones stored by posterior pituitary and are secreted by hypothalamus. (sabkuchonline.pk)
• The posterior pituitary does not produce its own hormones. (medscape.com)
• The hypothalamus produces 2 hormones, vasopressin (VP) and oxytocin (OXT), that are secreted from the nerve axons into the capillary beds that supply the posterior pituitary, where they are stored in cells and ultimately released into the circulation. (medscape.com)
• The other part, the posterior pituitary, consists of neural tissue and is essentially an extension of the brain. (pharmaceuticalintelligence.com)
• As an extension of the brain, the posterior pituitary contains axons from neurons in the hypothalamus. (pharmaceuticalintelligence.com)
• the important ones for the posterior pituitary are the paraventricular and supraoptic nuclei. (pharmaceuticalintelligence.com)
• The neurons that extend into the posterior pituitary produce either the hormone arginine vasopressin (abbreviated AVP) or the hormone oxytocin. (pharmaceuticalintelligence.com)
• The axon terminals abut tiny capillaries in the posterior pituitary. (pharmaceuticalintelligence.com)

Thyroid-stimula3

• GABA can either stimulate or inhibit the secretion of luteinizing hormone (LH) and growth hormone (GH) and can stimulate the secretion of thyroid-stimulating hormone (TSH). (wikipedia.org)
• Thyroid-stimulating hormone (thyrotropin) controls the rate of secretion of thyroxine and tri-iodothyronine by the thyroid gland- regulates most intracellular chemical reactions in the body. (sabkuchonline.pk)
• Among the main stimulatory factors are the pituitary tropic hormones, thyroid-stimulating hormone (TSH) or thyrotropin and adrenocorticotropic hormone (ACTH), which regulate the growth and function of their respective target cells, and the insulin/insulin-like growth factor system, that, through its mitogenic effects, can stimulate the proliferation of these cells.

Involving the pituitary gland1

• This may result from disorders involving the pituitary gland, hypothalamus, or surrounding structures. (medscape.com)

Hypothalamus6

• It is functionally connected to the hypothalamus by the median eminence via a small tube called the Pituitary Stalk. (sabkuchonline.pk)
• The pituitary hormones, or target organ hormones, can influence the hypothalamus and the pituitary to decrease or increase pituitary hormone secretion through long and short feedback loops. (medscape.com)
• The interaction between the hypothalamus, pituitary, and other endocrine glands is known as the hypothalamic-pituitary-endocrine axis. (pharmaceuticalintelligence.com)
• In another, we examine a phenomenon called a negative feedback loop, in which hormones from endocrine glands influence the action of the hypothalamus. (pharmaceuticalintelligence.com)
• The hormonal control center of the body can be found at the base of the brain, in a tiny pea-sized structure, called the pituitary gland, and an overlying region, called the hypothalamus. (pharmaceuticalintelligence.com)
• However, the hypothalamus wields even greater power, because it controls the pituitary gland. (pharmaceuticalintelligence.com)

Endocrine glands5

• Tropic hormones are named for their ability to act directly on target tissues or other endocrine glands to release hormones, causing numerous cascading physiological responses. (wikipedia.org)
• Pituitary Gland: An endocrine gland, about the size of a pea, that sits in a small, bony cavity at the base of the brain whose secretions control the other endocrine glands and influence growth, metabolism, and maturation. (sabkuchonline.pk)
• The pituitary gland secretes hormones regulating homeostasis, including tropic hormones that stimulate other endocrine glands. (sabkuchonline.pk)
• In one animation, we examine the hypothalamic control of the pituitary gland, and we show the endocrine glands that the pituitary controls. (pharmaceuticalintelligence.com)
• Because the pituitary controls many other endocrine glands, it is known as the "master gland" of the body. (pharmaceuticalintelligence.com)

Prolactin1

• Prolactin promotes mammary gland development and milk production and influences the secretion of estrogen/progesterone. (sabkuchonline.pk)

Trophic2

• Trophic hormones directly affect growth either as hyperplasia or hypertrophy on the tissue it is stimulating. (wikipedia.org)
• When pituitary hormone production is impaired, target gland hormone production is reduced because of a lack of trophic stimulus. (medscape.com)

Adrenal2

• This heterogeneity appears to constitute the underlying cause for the focal cell hyperplasia and eventually the formation of thyroid and adrenal nodules, under the influence of growth stimulatory factors. (mdpi.com)
• The predominance of one or the other of these growth stimulatory factors appears to determine the natural history of thyroid and adrenal nodular disease. (mdpi.com)

Signals1

• It links the two by sending and receiving signals from other regions of the nervous system while also controlling the body's "master gland"-the pituitary gland. (pharmaceuticalintelligence.com)
