This video tutorial explores the Tentorium Cerebelli, an extension of the dura mater. It describes its Latin origin, appearance, anatomical position, and attachments. The Tentorium Cerebelli divides the cranium into supratentorial and infratentorial compartments, supporting the cerebellum and separating it from the occipital lobe. The video details its borders, margins, and associated sinuses, providing a comprehensive understanding of its function and structure. Additional resources for further learning are also mentioned.
