The Pituitary Gland Anatomy of the pituitary gland: The pituitary gland is sometimes called the master gland of the endocrine system, because it controls the functions of the other endocrine glands. The pituitary gland is no larger than a pea, located at the base of the brain. The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers. The pituitary gland itself consists of three sections: the anterior lobe the intermediate lobe the posterior lobe ...

N2 - To begin analysis of the DNA sequences necessary for luteinizing hormone (LH) gene transcription, fusion genes containing the 5′ flanking region of the rat LHβ or the human α-subunit gene linked to luciferase were transfected into primary cultures of rat pituitary cells. The LHβ-luciferase construct was expressed in the primary cultures at a level 50 times greater than a promoterless luciferase control plasmid. Little or no expression of the LHβ-luciferase construct was detected following transfection of MCF-7, JAR or GH3 tumor cell lines. Treatment of transfected cells with gonadotropin-releasing hormone resulted in a modest induction of LHβ-luciferase activity. Considerably higher levels of ...
Located in the center of the brain, the pituitary gland manufactures and secretes hormones that regulate growth, sexual development and functioning, and the fluid balance of the body. About 10% of all cancers in the skull are pituitary tumors...
So, what happens if this very important gland does not properly perform its vital functions because it is either over or under stimulated? Since hormones control just about everything, then just about anything symptomatically can potentially occur. The most common problem I see with the pituitary gland is low function or suppression. That is, the pituitary just simply does not respond even when it is supposed to. Therefore, if estrogen drops, a suppressed pituitary gland does not respond with FSH and the net result is continued low estrogen. But here is the tricky part. When the pituitary is functionally suppressed, further suppression equals significant symptoms to the body as a whole. The three most likely pituitary suppressants in my testing are: insulin, white sugar and cortisol. So once again we see that when under stress (cortisol increase) sweets are craved and ingested (sugar) resulting sooner or later in hypoglycemia (insulin surges) or insulin resistance, all of which further suppress ...

Coronal computed tomographic scans of the pituitary gland in 27 normal children, adolescents, and young adults (ages, 8-21 years) and in a comparison group of adults (ages, 24-91 years) were evaluated retrospectively to test the applicability of published criteria for size and configuration of normal adult pituitary glands to younger patients. Statistically significant differences were found between the two groups, indicating that the pituitary gland in adolescents, particularly girls, is larger than in younger or older patients. The authors suggest that pubertal pituitary hyperplasia accounts for these findings. They conclude that standards for normal pituitary glands are probably inappropriate for adolescents. ...

Pituitary cancer is characterized by the abnormal growth in the pituitary gland. It affects the functioning of the pituitary gland and may cause an increased or decreased level of pituitary hormone secretions within the body. The small pituitary cancer treatment is accessible through noninvasive treatment or medicines. But, a large pituitary cancer treatment is challenging to treat because of its complex nature.
Endoscopic Pituitary Surgery Endoscopic pituitary surgery, also called transsphenoidal endoscopic surgery, is the most common surgery used to remove pituitary tumors. The pituitary gland is located at the bottom of your brain and above the inside of your nose. It is responsible for regulating most of your bodys hormones, the chemical messengers that travel through your blood. Endoscopic pituitary surgery is done with an instrument called an endoscope. An endoscope is a thin, rigid tube that has a micro...

The nucleotide sequence of the longest of two different tLHβ cDNA clones contained 592 bp, and included 23 bp of the 5 untranslated region (UTR) and 92 bp of the 3 UTR in addition to a 477 bp open reading frame that encoded a 39 amino acid leader polypeptide and a 120 amino acid mature apoprotein. Turkey and chicken LHβ sequences shared approximately 92 and 93% nucleotide and amino acid sequence similarities respectively. Northern blot analysis of total cellular anterior pituitary RNA showed that an approximate 800 base transcript hybridized to a 32P-labelled tLHβ cDNA ...
The pituitary gland, through the little-known hypothal-amus that lies directly above it, is also the appetite center and the sleep center of the body. Loss of appetite, and insomnia! Two universal complaints found in thousands of the past-forty group who have strayed from the rules of good nutrition.Exhaustive research has discovered that the pituitary is extremely sensitive to diet. If you do not eat enough high-protein foods (meat, especially, seems to have a stimulating effect on this gland), then your pituitary cannot produce a normal supply of its own dozen or more vitally needed hormones which, themselves, are made of protein. In addition to protein, the pituitary is stimulated by vitamin E (richest source is wheat germ); and increased amounts of vitamin A either in foods or in concentrated form, have directly beneficial effects on the entire endocrine group ...

The bearing of these results on the Herring-Cushing theory of pituitary secretion is apparent. For the first time a true secretion antecedent has been demonstrated in the cells of the pars intermedia, an antecedent which appears in the cells at the same period of development at which active pressor effects may be obtained from the gland extracts. The route of export of this material from the gland to its point of utilization, however, is unknown; it may go by way of the blood or, as required by the Herring theory, by the transneural route to the third ventricle. The objections to the latter conclusion have been amply expanded in the introduction to this paper, but here may be emphasized the fact that the fetal pig hypophysis contains no hyaline bodies. Indeed they are rare in the adult, though there may be seen in the cells of the pars nervosa in the processes of its intrinsic cells, granular deposits which we believe to be the antecedents of the hyaline bodies but which in the pig rarely are ...

Immunocytochemical and morphometric changes of pituitary FSH and LH cells in juvenile (17th day of life) female rats neonatally (4th day of life) treated with five 0.25 mg doses of estradiol dipropionate (EDP) or human chorionic gonadotrophin (14th and 16th day of life) and with the combination of both were studied using rabbit antirat beta-follicle stimulating hormone (FSH) and beta-luteinising hormone (LH) sera and a peroxidase-antiperoxidase (PAP) immunohistochemical procedure. Morphometry and stereology were applied to evaluate the changes in FSH- and LH-producing cells, number and volume densities of the cells and the nuclei. In EDP-treated females significantly increased pituitary mass and the number of chromophobes and PRL cells were observed while all morphometric parameters of FSH/LH cells were decreased in comparison with the corresponding controls. This difference was much more prominent in FSH-beta- than in LH-beta cells. Treatment with hCG led to an increase in the number of FSH and ...

The Pituitary Gland, or Hypophysis Cerebri, is a small and hard body about six lines broad, three long and three high. It is always formed of an anterior bean-shape, and a posterior and more rounded lobe, which are uniformly united. Its component parts, we are told, are almost identical with those of the Pineal Gland; yet not the slightest connection can be traced between the two. To this, however, Occultists take exception; they know that there is a connection, and this even anatomically and physically. Dissectors, on the other hand, have to deal with corpses; and, as they themselves admit, brain-matter, of all tissues and organs, collapses and changes form the soonest--in fact, a few minutes after death. When, then, the pulsating life which expanded the mass of the brain, filled all its cavities and energized all its organs, vanishes, the cerebral mass shrinks into a sort of pasty condition, and once open passages become closed. But the contraction and even interblending of parts in this ...

In the fall, measuring a horses adrenocorticotropic hormone (ACTH) levels is often used as a diagnostic tool for pituitary pars intermedia dysfunction (PPID, also known as equine Cushings disease). It peaks between mid-August to mid-October as part of the metabolic preparation for winter and results in levels anywhere up to about three times those found…
The menopausal ovary, in the absence of eggs, is unable to produce significant amounts of the female sex hormones. If a blood test is done to measure the levels of estrogen and progesterone, they will be found to be at significantly low levels. The function of the ovaries is under the control of the pituitary gland, found at the base of the brain and functions as the master controller for the many hormonal glands in the body. The pituitary gland is very sensitive to the hormonal output of the ovaries and it begins to react when the ovaries fail to produce estrogen and progesterone in the bloodstream. The pituitary gland compensates with the failure of the menopausal womans ovaries. It quickly starts to secrete large amounts of a hormonal messenger known as the follicle stimulating hormone, stimulating the ovaries to put them back into action. But still, the ovaries have stopped producing estrogen and progesterone, despite the hormonal stimulation of the pituitary gland and the ovaries remain ...

ABSTRACT: We model the effect of gonadotropin-releasing hormone (GnRH) on the production of luteinizing hormone (LH) by the ovine pituitary. GnRH, released by the hypothalamus, stimulates the secretion of LH from the pituitary. If stimulus pulses are regular, LH response will follow a similar pattern. However, during application of GnRH at high frequencies or concentrations or with continuous application, the pituitary delivers a decreased release of LH (termed desensitization). The proposed mathematical model consists of a system of nonlinear differential equations and incorporates two possible mechanisms to account for this observed behavior: desensitized receptor and limited, available LH. Desensitization was provoked experimentally in vitro by using ovine pituitary cells in a perifusion system. The model was fit to resulting experimental data by using maximum-likelihood estimation. Consideration of smaller models revealed that the desensitized receptor is significant. Limited, available LH ...

People know the fact that the growth hormone shortage is the effect of the underperforming and drifting pituitary gland. This could be congenital or even attained in nature. This problem can be the result of lack of secretion or even low production of HGH, or somatotropin, by the gland. Even, some of the people out there are born with GHD and doctors say that it is for the hereditary. Inherited GHD has been connected to the irregularity of pituitary gland, and it can also be the effect of another disorder. This has also been observed that kids who have the cleft palates or even lips are more likely to have the condition as they usually have badly-developed pituitary gland. But if you treat well, then there is a chance of curing HGH deficiency. Learn more about HGH deficiency in this website https://www.genf20plus.info/hgh-deficiency.php. ...

Testosterone, is also produced by the ovaries and plays a role in generating energy, developing muscle mass and stimulating sexual desire.. The balance of these hormones in your body at any given time is affected by many factors. The pituitary gland, a gland found at the base of your brain, and your ovaries are constantly communicating via their respective hormones, dictating the changing hormone levels of your monthly cycle and the production of eggs. The pituitary gland produces a follicle-stimulating hormone among other hormones. Medications, stress, body weight (over or under), time of day and even time of the moth can all cause temporary changes in your hormone.. Once we reach the Matriarch Phase of life, permanent changes to the hormone levels and hormone balance occur. The ovaries will slowly begin to stop releasing eggs, which at this point may no longer be viable. When this happens they also quit producing their hormones. This will usually happen over a period of time, beginning ...
