. The anatomy of the central nervous system of man and of vertebrates in general. Neuroanatomy; Central Nervous System. THE FORM-KELATIONS OF THE HUMAN" BEAIX. 195 ascends toward the edge of the hemisphere and thus considerably interrupts the continuity. This branch, the fissura retrocentralis superior, often occurs independent of the interparietal Assure. Tlie interparietal fissure allows the recognition of three divisions, which are occasionally separate from one another. The anterior division is called the fissura retrocentralis inferior, the posterior the sulcus occipitalis ante- terior or perpendicular is. The portion of the inferior parietal lobule which surrounds the end of the fissure of Sylvius is called the gyrus marginalis. The part that lies just back of this and arches around the superior temporal sulcus is the gyrus. Fig. 131.—Lateral aspect of brain. angularis. The former gyrus is at once observed on every brain; the latter must be searched for mth some diligence. It is found in the space bounded above by the interparietal fissure and below by the superior temporal sulcus; that is to say, its end. Its posterior part, indeed, just surrounds the end of this sulcus. The region of the gyrus angularis is an important one, and it is therefore advantageous to be able to locate and bound it well. The small gyrus directly posterior to it is the gyrus parietalis posterior. The occipital lohe is not so uniformly fissured in all brains that the convolutions described by writers as superior, middle, and inferior may be easily identified without elaboration. It is commonly separated from the parietal lobe by the anterior occipital sulcus, which passes vertically down-.
