Dura Mater, Ventral View

Description

Presented from an inferior (ventral) cranial perspective, the meningeal dura mater is shown lining the internal cranial base, with the central region of the sella turcica and parasellar dura framing the cavernous sinus on either side of the body of the sphenoid. Laterally, the dura conforms to the grooves and ridges of the middle cranial fossa and approaches the petrous part of the temporal bone; posteriorly it continues toward the clivus and posterior cranial fossa, where the cerebellum sits inferior to the occipital lobes. A split composition pairs the left hemicranium’s osseous floor, including multiple skull base foramina, with the right side’s exposed brain surface, where cerebral gyri and sulci and the folded cerebellar folia provide topographic correlation, and yellow cranial nerve trajectories emphasize foraminal exit pathways. That parasellar dura matters because it is where neurosurgeons and skull base teams live when working around pituitary lesions, cavernous sinus meningiomas, and internal carotid artery pathology. The cavernous sinus region is a compact crossroads: cranial nerves III, IV, V1, V2, and VI course in or along the lateral wall and lumen, and small spatial shifts here explain the classic ophthalmoplegia, facial sensory change, or diplopia seen with cavernous sinus thrombosis and invasive pituitary macroadenoma. The inferior view also clarifies how the dura relates to the foramen ovale and foramen spinosum, landmarks for percutaneous trigeminal procedures and middle meningeal artery considerations. Use this plate in neuroanatomy and head and neck anatomy teaching to tie meningeal reflections and dural venous sinus anatomy to the skull base foramina and cranial nerve exits, and in surgical atlases covering transsphenoidal and endoscopic endonasal corridors. It also fits radiology education when correlating parasellar MR/CT findings with the dural envelope and adjacent neurovascular contents.
