The Surface and Intracranial Location of Asterion.

Background: Asterion is identified as the connection point of sutura parietomastoidea, sutura occipitomastoidea, and sutura lambdoidea. The location of asterion, which is primarily preferred as a landmark during posterolateral surgical approach for intracranial operations, shows many variables. The aim of this study was to identify the surface location of the asterion and determine the distances between intracranial anatomical structures and asterion.

A geometric description of human intestine.

Mathematical models of natural phenomena play a central role in the physical sciences. Moreover, modeling of the organs draws from some beautiful areas of mathematics, such as nonlinear dynamics, multiscale transforms and stability analysis. In this study, a geometric recognition of the separate intestine sections (duodenum, jejunum, ileum, cecum and colon) of the human is presented.
