OBJECTIVES: • Identify appropriate hypothalamic factors that control the secretion of each of the anterior pituitary hormones, and describe their route of transport from the hypothalamus to the anterior pituitary. • Contrast the anterior and posterior pituitary lobes with respect to cell types, vascular supply, development, and innervation (hypothalamic). • Diagram the short-loop and long-loop ...

background: asparagus is a plant with high nutritional, pharmaceutical, and industrial values. objective: the present study aimed to evaluate the effect of aqueous extract of asparagus roots on the hypothalamic-pituitary-gonadal axis hormones and oogenesis in female rats. materials and methods: in this experimental study, 40 adult female wistar rats were divided into five groups, which consist ...

Purpose of the study . Was to analyze changes in pathophysiological parameters transplantable tumor growth and functional activity hypothalamic-pituitary-thyroid axis (HPT) rats both sexes with Guerin's carcinoma presence induced hypothyroidism. Materials methods The dynamics average life span were assessed white alley Guerins transplanted subcutaneously on background thyreostatic RIA (radioimm...

The effects of prostaglandin E1 (PGE1) and indomethacin (IDM) on the release of several pituitary hormones from the rat pituitary were investigated in vitro. An addition of 2 microng/ml of PGE1 to the medium elicited the release of growth hormone (GH) and prolactin, but not of adrenocorticotropin (ACTH) and luteinizing hormone (LH). Although the addition of 1 microng/ml of IDM alone resulted in...

Incidental pituitary adenoma is the common finding during brain imaging. According to multistep model of pituitary tumourigenesis genetic alterations provide the initiating event that transforms cells while hormones play a role in promoting cell proliferation. Development of pituitary adenoma in a case of excessive hypophysiotrophic hormones production or reduced feedback suppression by target ...

Professor P. M. Daniel has described in the first paper the nervous pathways connecting the hypothalamus to the posterior pituitary and how the posterior pituitary merely stores the hormones vasopressin, oxytocin (which has no clearly defined function in man), and neurophysin, the large molecule or molecules which bind the other hormones. For many years the anterior pituitary was thought to be ...

As it regulates important physical functions and general wellbeing, the hypophysis plays a major role in responding to increased demand for different hormones. In current review, we described anatomical histological structures of pituitary glands domestic animals. Unlike other glands, gland has two main parts; adenohypophysis (anterior lobe), which contains multiple populations endocrine cells ...

Empty sella turcica is a condition in which the pituitary gland absent completely or partially from fossa. The patient may be asymptomatic with empty as an incidental finding, have symptoms of hormones deficiency. Perioperative management these patients depends on and signs hormonal deficiencies replacement treatment.
