Pituitary gland

Pituitary gland: Encyclopedia - Pituitary gland

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. ...

Pituitary gland: Encyclopedia - Anterior pituitary

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 ...

A gland is an organ in an animal's body that synthesizes a substance for release such as hormones, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland). Gland - Types of gland. Humans have a large variety of glands, from the pituitary gland in the brain, to sweat glands over the body's skin that release perspiration to regulate the body's temperature.

Pituitary gland: Encyclopedia - Cabergoline

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 ...

Pituitary gland: Encyclopedia - Acromegaly

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 ...

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 ...

Pituitary gland: Encyclopedia - Adrenocorticotropic hormone

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 ...

Pituitary gland: Spiritual - Theosophy Dictionary on Pituitary Gland, Hypophysis Cerebri

Pituitary Gland or Hypophysis Cerebri A small, bi-lobed, ductless gland, resting on the bony floor of the brain just above the palate. Its familiar name came from the mistaken notion that it secreted pituita (phlem) which was discharged through the nose. The technical term describes it as the "growth underneath" the brain with which it is connected. It is also closely related to the optic and other sensory nerves, as well as to the general coordinating centers of mental and physical sense and sensation in the region of the third ventricle, including the pineal gland.

Modern physicians have called the pituitary the driver gland, because of its active influence upon the growth and function of different parts of the body. Theosophy holds that the pituitary body is the seat of the organ of will; likewise, as an organ that functions through the sympathetic nervous system upon various levels of the psychic plane, it is one of the links that connect the intermediate nature of man with both his spiritual mind and his instinctual, animal mind. Thus it serves as manifesting point where the cosmic force of will, flowing through the spiritual center of man's being, works as a physical energy. As the bodily organ of will, it acts as a vital transformer, stepping down the high power, electromagnetic currents of universal will and desire, thus providing a series of special currents of growth which are diffused through the thyroid and other ductless glands. These currents, acting as automatic or vegetative will power, first affect the linga-sarira (model-body), and through it stimulate the physical body.

The pituitary, as a transformer, may also step up these diffused currents of physical and animal will and desire, raising them into the aspiring mental-spiritual will and desire, as when the high adepts concentrates his whole consciousness upon attaining spiritual vision and knowledge. When the focused power of the active pituitary is directed to the higher psychic levels, its influence, through radiated wave-energy, reaches the pineal gland which responds with spiritual clairvoyance. If, however, the increased activity is upon the lower astral levels, the effects are distorted and misleading. The pituitary being closely connected with the optic and other sensory nerves, and with the important nerve centers, its enlargement or uncontrolled, abnormal activity often give rise to strange hallucinations of vision, hearing, etc. This explains the bizarre sights, sounds, odors, or what not, which are so real to the sufferers from brain fever, delirium tremens, insanity, epilepsy, and some other disorders.

However, no one of the organs of a human being can function alone and apart from coordinated activity with the other parts of the human constitution; thus it is that while the pituitary body can stimulate or arouse to increased activity the pineal gland, nevertheless the pineal gland in its turn can act strongly upon the pituitary body; and as the pineal gland is the physical seat of the spiritual and higher intellectual faculties of the human constitution descending to the physical brain through the linga-sarira, when the pineal gland thus influences by radiated wave-energy the pituitary, the latter is awakened and begins to vibrate, strongly influencing the physical brain with will-currents guided by the spiritual and higher intellectual inspiration from the pineal.
