Foramen rotundum - Wikipedi

Das Foramen rotundum ist die Durchtrittsstelle für den Nervus maxillaris, eines Astes des V. Hirnnervs. Bei Wiederkäuern und Schweinen ist das Foramen rotundum mit der Fissura orbitalis zum Foramen orbitorotundum verschmolzen The foramen rotundum allows the passage of the maxillary nerve (V 2), a branch of the trigeminal nerve. It also allows the passage of the artery of the foramen rotundum and an emissary vein. History Etymology. Foramen is the Latin term designating a hole-like opening. It derives from the Latin forare meaning to bore or perforate. Here, the opening is round as indicated by the Latin rotundum meaning round

Der Nervus maxillaris zieht in der basolateralen Wand des Sinus cavernosus nach ventral, wo er vor seinem Durchtritt durch das Foramen rotundum einen Ramus meningeus abgibt. Über das Foramen rotundum erreicht er die Fossa pterygopalatina. Dort teilt er sich in seine Endäste: Nervus zygomaticus, Nervus infraorbitalis, Rami ganglionares Danach verlässt der Nervus ophthalmicus die mittlere Schädelgrube (Fossa cranii media) durch die Fissura orbitalis superior in Richtung Augenhöhle (Orbita). Der Nervus maxillaris zieht durch das Foramen rotundum

Der Augenast zieht zur Augenhöhle, um sich dort in seine Endäste aufzuteilen. Der Oberkieferast verlässt durch ein Loch an der Unterseite des Schädels (Foramen rotundum) den Schädel und zieht Richtung Oberkiefer, wo er sich in seine Endäste aufteilt. Der Unterkieferast zieht zusammen mit den motorischen Fasern zum Unterkiefer und gibt dort die Endäste ab The maxillary nerve leaves the skull through the foramen rotundum and arrives in the superior part of the pterygopalatine fossa (Fig. 16.1). It enters the inferior orbital fissure, crosses the infra-orbital groove, and appears on the face through the infra-orbital foramen. At its origin it is surrounded by a double layer of dura mater Foramen Rotundum. The foramen rotundum is located at the base of the greater wing of the sphenoid, inferior to the superior orbital fissure. It provides a connection between the middle cranial fossa and the pterygopalatine fossa.

The foramen rotundum appears as a round opening in the great wing of the sphenoid bone that extends anteriorly into the pterygopalatine fossa and transmits the maxillary nerve ; it lies above and lateral to the pterygoid canal Foramen rotundum is a term used to describe a rounded hole or opening in the sphenoid bone of the skull, which in turn joins the pterygopalatine fossa and the middle cranial fossa. It transfers the trigeminal nerve's maxillary nerve branch, the emissary veins, and the foramen rotundum's artery. Foramen has its origins in Latin, wherein the.
