. Cunningham's Text-book of anatomy. Anatomy. 65-4 THE NERVOUS SYSTEM. the parietal tuberosity of the cranial wall by turning upwards into the parietal region in the form of an ascending terminal piece. The anterior horizontal ramus extends horizontally forwards in the frontal region for a distance of not more, as a rule, than three-quarters of an inch, immediately above and parallel to the posterior part of the superciliary margin of the hemisphere. The ascending ramus proceeds upwards, with a slight inclination forwards, into the inferior part of the lateral surface of the frontal region for a variable distance (an inch or less). In many cases the two anterior limbs spring from a common stem of greater or less length, and not infrequently there is only a single anterior Sulcus Circularis.âIf the lips of the posterior ramus of the lateral fissure are pulled widely asunder from each other, the insula (island of Reil) will be seen at the Inferior precentral sulcus Inferior frontal gyrus (posterior part) | Superior frontal I gyrus (inter- I Intei-raediate part of inferior frontal gyrus mediate part) Gyrus frontalis superior (anterior part) \ Sulcus' aterior ascending ramus of lateral fissure ^ -, diagonals Anterior part of inferior frontal gyrus * Middle frontal area Middle frontal gyrus (posterior part) Gyrus frontalis superior Superior precentral sulcus.
