Study of Health in Pomerania Pomeranian adult population. In the Northeast of Germany nearly 50% - 60% indicate these diseases. SHIP is the first population based cohort study worldwide which includes whole-body MRI. The aims of the following main whole body-MRI study are: (1)To provide prevalence estimates for different MR findings in a general adult population. (2)To establish population-based MRI reference parameters for various organs and organ parts such as left and right ventricular size or volume of liver, spleen, kidney, prostate, and brain structures . Clinical MR reference parameters currently in use were derived from small, nonrepresentative samples and are thus prone to selection
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
