    S01876886 UI317-01 Assignment #3: Reflections 1. Hormones and the brain are powerful influences on human sexual functioning. Perhaps two of the most important portions of the brain in terms of sexual functioning are the hypothalamus and the pituitary gland, which make up the HPG axis. The HPG axis consists of the hypothalamus, pituitary gland, and the gonads – gonads being the testes in males and the ovaries in females. Together, the HPG axis regulates sex hormone production in a negative feedback loop. Three important hormones that are produced from this process are follicle-stimulating (FSH) hormone; luteinizing hormone (LH); and gonadotropin-releasing hormone (GnRH.) These hormones help to regulate the pituitary gland’s production of…

    Leptin The gene LEP is found in chromosome 7 in humans. It is a protein of 167 amino acids with a four-helix bundle motif similar to that of a cytokine. It is produced mostly in the white adipose tissue. It then circulates in the bloodstream at fluctuating levels, depending on the circumstances of its production. For example, Leptin levels are normally higher at the hours between midnight and early morning; it is assumed that this is to suppress appetite during sleep. Leptin is believed to enter…

    ABSTRACT: Profitable animal production require high fertility animals that exhibit healthy ovarian follicles, which contributes to estradiol synthesis. Follicle maturation relies on coordination between pituitary hormones and intraovarian signaling pathways. Recently Wnt/beta-catenin signaling has been established as necessary modulators of folliculogenesis in response to FSH. In granulosa cells (GC), beta-catenin is a central key in regulation of aromatase (Cyp19a1) expression. In addition,…

    production of each hormone is kept balanced by the feedback mechanism between the individual gland (the thyroid, for example), the hypothalamus, and the pituitary gland. If a gland overproduces or underproduces a hormone, the master glands register this from the amount of hormone in the bloodstream. The master glands then respond by regulating the hormonal production. The system works with great precisior; despite the fact tat the hormones are transported in the bloodstream and are disseminated…

    ENDOCRINAL GLANDS Patients with anorexia nervosa have a number of abnormalities in endocrine function. Secretion rates of cortisol are generally elevated,and metabolic clearance rates are decreased, with the result that the half-life of cortisol may be prolonged in malnourished individuals. The clinical significance of this elevated cortisol level is unknown, but it may be involved with loss of bone density in anorexia nervosa(Lo Sauro et al., 2008). Alterations in growth hormone are also…
