Topographic and anatomical features of pachyonic granulations
Aim: this article examines the anatomy of the location and external. Objective: to study the anatomy and topography of pachyonic granulations and their projection on the dorsolateral surface of the hemisphere. Materials and methods: brain preparations with preserved arachnoid membrane. Preparation, staining, statistical analysis method and graphological method. Results: after coloring brain preparations, it is clearly possible to determine the extent of localization of pachyonic granulations in the form of parallel wide bands along the longitudinal slit of the brain on each hemisphere. The number of granulations in the left hemisphere was - 615 ± 57, and in the right - 472 ± 42. We noted the absence of localization of arachnoid granulations in certain areas. Conclusion. The conducted research is of fundamental importance for studying the process of outflow of cerebrospinal fluid through pachyonic granulations. The topographic and anatomical data obtained by us can be used to describe the functional activity of pachyonic granulations and will serve as a source for their further study.
