International Society of Nephrology research, diagnosis, treatment, and prevention of kidney disease. The ISN has over 9,000 professional members from more than 126 countries. 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. In 1992 the society formed a task
Circumventricular organs that information neurally to other brain regions. Through their neural circuitry, they provide direct information to the autonomic nervous system from the systemic circulation. The secretory organs include the subcommissural organ (SCO), the pituitary gland, the median eminence, and the pineal gland. These organs are responsible for secreting hormones and glycoproteins into the peripheral blood using feedback from both the brain environment and external stimuli. All of the circumventricular organs, except the subcommissural organ, contain extensive vasculature and permeable capillaries which define a sensory and secretory system within the brain. Furthermore, all CVOs contain neural tissue, enabling a neuroendocrine role.
