In addition, the ISN closely collaborates with over 75 national and regional nephrology societies around the world, representing about 20,000 professionals. The ISN continues to develop and consolidate several programs, initiatives and partnerships that will help to further deliver on its two overarching goals: reducing the incidence and impact of kidney disease worldwide, and making the ISN the leading international organization for all issues related to the science and practice of global nephrology.

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
