The anterior pituitary (also called the adenohypophysis) comprises the anterior lobe of the pituitary gland and is part of the endocrine system. Under the influence of the hypothalamus, the anterior pituitary produces and secretes several peptide hormones that regulate many physiological processes including stress, growth, and reproduction. Anterior pituitary - Anatomy and development. The adenohypophysis is a pea-size gland anterior to the neurohypophysis, caudal to the hypothalamus, and sits in the ...

The diagnosis is generally entertained either on the basis of visual difficulties arising from the compression of the optic nerve by the tumor, or on the basis of manifestations of excess hormone secretion: the specifics depend on the type of hormone. Tumors which cause visual difficulty are likely to be macroadenomas greater than 10 mm in diameter; tumors less than 10 mm are microadenomas. The most common secretory pituitary tumor is the prolactinoma, which can cause galactorrhea, hypogonadism, amenorrhea, infertility, ...

The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in the small, bony cavity (sella turcica) at the base of the brain. Its posterior lobe is connected to a part of the brain called the hypothalamus via the infundibulum (or stalk), giving rise to the tuberoinfundibular pathway. The posterior lobe is thus derived from neural ectoderm while the anterior lobe is derived from oral ectoderm. The anterior pituitary lobe receives releasing hormones from the hypothalamus via a portal vein system. ...

Kriya Yoga: The Breath of God Is Our Breath of Life

Kriya Yoga gives extreme importance to the breath. It teaches that breath control is self control, breath mastery is self mastery, it is deathlessness. If you take a very short breath and seek God in the fontanel and the pituitary, you will attain calmness and God realization. The Bhagavad Gita, verse 5:27, mentions this short breath: "We are to fix our attention in the pituitary, take a very short breath and touch Him in the pituitary and in the fontanel." The breath must be so short that if you place your finger in front of your nose, the outgoing breath will not touch the finger.

Corticotropin-releasing hormone (CRH), also called corticotropin-releasing factor (CRF) or corticoliberin, is a polypeptide hormone involved in the stress response. It is produced by the hypothalamus and stimulates corticotropic cells of the anterior lobe of the pituitary to produce ACTH and other biologically active substances (for example β-endorphin). CRH is also synthes ...

Acromegaly (from Greek akros "high" and megalos "large" - extremities enlargement) is a hormonal disorder that results when the pituitary gland produces excess growth hormone (hGH). Most commonly it is a benign hGH producing tumor derived from a distinct type of cells (somatotrophs) and called pituitary adenoma. Acromegaly most commonly affects middle-aged adults and can result in serious illness and premature death. Because of its insidious onset and slow progression, the disease is hard to diagnose in the ...

Image:Bromocriptine.png Bromocriptine G02CB01 N04BC01 Bromocriptine is an ergoline derivative dopamine agonist that is used in the treatment of pituitary tumors and Parkinson's disease. Amenorrhea, female infertility, galactorrhea, hypogonadism, and acromegaly may all be caused by pituitary problems, and therefore, these problems may be treated by this drug. It is also used following stillbirth to suppress the mother's produc ...

Cabergoline (name brands Dostinex and Cabaser) is a dopamine receptor agonist and uncategorized drug which suppresses the production of prolactin in pituitary gland. It is an ergot-derivative. It is used to prevent the production of excess prolactin in the case of certain pituitary tumors, and in some countries (including the United States) has been approved as a therapy for Parkinson's Disease. The normal dosage for prolactinoma is 0.5 mg twice we ...

Bitemporal hemianopsia is the medical description of a type of partial blindness that is associated with lesions of the optic chiasm, the area where the optic nerves from the right and left eyes cross near the pituitary gland. The absence of vision in half of a visual field is described as hemianopsia. The visual field of each eye can be divided in two vertically, with the outer half being described as temp ...

The arcuate nucleus is a collection of neurons present in the hypothalamus. Some arcuate neurons contain dopamine and inhibit the release of prolactin by the pituitary. Other neurons contain neuropeptide Y (NPY) and affect hunger. When activated, these neurons can produce ravenous eating. These neurons are probably regulated by glucose, insulin, and leptin. Thus, arcuate neurons are responding to information on whether the body h ...

Adrenocorticotropic hormone (ACTH or corticotropin) is a polypeptide hormone synthesised (from POMC, pre-opiomelanocortin) and secreted from corticotropes in the anterior lobe of the pituitary gland in response to the hormone corticotropin-releasing factor (CRF) released by the hypothalamus. ACTH stimulates the cortex of the adrenal gland and boosts the synthesis of corticosteroids, mainly glucocorticoids but also mineralcorticoids and sex steroids (androgens). Together with ACTH the hormones lipotropin, melanocyte-stimulating hormone (MSH), β-endorphin and met-enkephalin are also release ...

In the anatomy of mammals, the hypothalamus is a region of the brain located below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate certain metabolic processes and other autonomic activities. The hypothalamus links the nervous system to the endocrine system by synthesizing and secreting neurohormones often called releasing hormones because they function by stimulating the secretion of hormones from the anterior pituitary gland — among them, gonadotropin-releasing ho ...

Antidiuretic hormone (ADH), also known as arginine vasopressin (AVP), is a hormone that is mainly released when the body is low on water; it causes the kidneys to save water by concentrating the urine and is also involved in the creation of thirst.

Bovine somatotropin (bST), or bovine growth hormone (BGH), is a protein hormone that occurs naturally in the pituitary gland of cattle. It is a factor controlling the amount of milk produced by a dairy cow. Bovine somatotropin is naturally in the milk extracted from a cow. Bovine somatotropin - Physiology.

Despite its name, the posterior pituitary gland is not a gland, per se; rather, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary gland. Like the anterior pituitary, this tissue receives its blood supply from the hypophyseal artery, and secretes hormones into the hypophyseal vein. The posterior pituitary has three main components: pars nervosa inf ...
