The ASN holds annual meetings (Kidney Week) and subsequent regional meetings (ASN Highlights) to discuss new developments in the field of nephrology. The ASN also provides an Annual Board Review Course & Update and other online learning opportunities for both established nephrologists and those in training. In 2012, nearly 1,200 instructional hours were offered by ASN to physicians, researchers,
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
