American Society of Nephrology of the American Society of Nephrology" (JASN), the "Clinical Journal of the American Society of Nephrology" (CJASN), the "Nephrology Self-Assessment Program" (NephSAP), "ASN Kidney News and Kidney News Online", "In The Loop", and more recently the Kidney Self Assessment Program (KSAP). 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 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.
