Borders of the Cavernous Sinus Diagram

The Borders of the Cavernous Sinus diagram gives a clean cross-section view of this important dural venous space next to the pituitary. The walls are clearly marked—superior, inferior, medial, lateral—while the internal carotid artery and cranial nerves III, IV, V1, V2, and VI run through or along it. Seeing everything laid out helps explain why infections, clots, or aneurysms here can cause such serious symptoms and why pituitary surgery requires extra caution.
