Composed of over 16,000 physicians and scientists, ASN promotes expert patient care, advances medical research, and educates the renal community. ASN also informs policymakers about issues of importance to kidney doctors and their patients. Each year, the ASN and the ASN Foundation for Kidney Research provide nearly 400 research and travel grants. ASN annual meetings are attended by approximately 13,000 participants, and regional meetings are held throughout the year. The society publishes the "Journal
Circumventricular organs decrease in RF production. This finding implies that the subcommissural organ and its associated Reissner's fibers are an integral part of fluid electrolyte balance and water homeostasis. The pituitary gland is subdivided into two lobes, the anterior pituitary and the posterior pituitary (also known as the adenohypophysis and neurohypophysis respectively). Each one functions as a separate endocrine organ, and both are circumventricular organs. The anterior pituitary contains non-neural secretory cells derived from oral ectoderm which are indirectly controlled by "releasing hormones" from the median eminence of the hypothalamus, through the hypophyseal portal circulation. The posterior pituitary consists of axonal projections
