When stimulated by thyroid stimulating hormone/TSH from the anterior pituitary gland
in response to decreased circulating thyroid hormone leading to decreased negative feedback and TSH release, the thyroid gland releases about 90% T4 (pre-hormone), about 9% T3 (the active, stimulating form of thyroid hormone), about 1% RT3 (an inhibitory version of thyroid hormone), and a smidgen of T2.
This hypothesis was partly supported by reports showing that infusion of SCFA into blood, and/or an increase of SCFA in the medium bathing the anterior pituitary gland
cells, suppressed GHRH-induced GH release [4-6].
sup] Another possible explanation is interrelated to most of the precursors of nasopharyngeal origin remained in the clivus during the formation of the anterior pituitary gland
Distinguishing normal nonadenomatous anterior pituitary gland
from pituitary adenoma is best achieved through a combination of information gleaned from the TP and the frozen/permanent sections, because the latter may show crush artifact and the ability to distinguish preservation of acinar pattern either at frozen or permanent section can be seriously compromised by this.
In a major surgery that took place at the All India Institute of Medical Sciences (AIIMS) in New Delhi on 15 January, doctors removed the four-centimetre long tumour that had been forcing the anterior pituitary gland
to produce excess growth hormones (GH) in the woman, a medical condition generally known as acromegaly, The Indian Express (http://indianexpress.
13) The hypothalamus secretes thyrotropin-releasing hormone (TRH) and luteinizing-releasing hormone (LRH) to stimulate or suppress the production of anterior pituitary gland
hormones, which in turn stimulate the release of hormones and other substances from target organs.
Magnetic resonance imaging of the brain demonstrated a flattened anterior pituitary gland
within the sella, associated with absence of the infundibular stalk and an ectopic posterior pituitary gland (Fig.
Rathke's cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid filled cyst in the posterior portion of the anterior pituitary gland
A hypothalamic hormone, corticotropin-releasing hormone, controls the release of corticotropin from the anterior pituitary gland
The anterior pituitary gland
or adenohypophysis originates embryologically from Rathke's pouch and produces six hormones (Drouin, 201 I), including luteinizing hormone, follicle-stimulating hormone, prolactin, growth hormone, adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (Table 1).
Prolactin is a 198-amino acid protein (23-kD) produced in the lactotroph cells of the anterior pituitary gland
and its principal action is production and spontaneous flow of breast milk.
This growth process is stimulated by somatotrophin (growth hormone) released by the anterior pituitary gland
