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).

The posterior pituitary consists of axonal projections
