What passes ethmoid foramen?

The posterior ethmoidal foramen is a small opening in the ethmoid bone. It transmits the posterior ethmoidal artery, vein and nerve which supplies the posterior ethmoidal and sphenoid sinuses.

What passes through anterior and posterior ethmoidal foramina?

It transmits the posterior ethmoidal artery, vein and nerve which supplies the posterior ethmoidal and sphenoid sinuses. The distance between the anterior and posterior ethmoidal foramina is 12 to 15 mm. The distance between the posterior ethmoidal foramen and the optic canal is usually 3 to 7 mm.

Between which bones are foramen Ethmoidale formed?

The anterior ethmoidal foramen is a small opening in the ethmoid bone in the skull. Lateral to either olfactory groove are the internal openings of the anterior and posterior ethmoidal foramina (or canals)….

What is foramen Rotundum?

The foramen rotundum (plural: foramina rotunda) is located in the middle cranial fossa, inferomedial to the superior orbital fissure at the base of greater wing of the sphenoid bone. Its medial border is formed by lateral wall of sphenoid sinus.

What is a supraorbital foramen?

The supraorbital foramen or notch is the small opening at the central edge of the superior orbital margin in the frontal bone just below the superciliary arches that transmits the supra-orbital nerve, artery and vein.

What runs through foramen Spinosum?

The foramen spinosum (plural: foramina spinosa) is located in the posteromedial part of greater wing of sphenoid bone posterolateral to foramen ovale which connects the middle cranial fossa with the infratemporal fossa. It transmits the middle meningeal artery, middle meningeal vein, and (usually) the nervus spinosus.

What is the Supratrochlear nerve a branch of?

frontal nerve
Supratrochlear nerve: The supratrochlear nerve is a branch of the frontal nerve (branch of the ophthalmic division of the trigeminal nerve).

What runs through foramen Lacerum?

The two nerves that pass from the foramen lacerum are the greater petrosal nerve, which represents the pre-ganglionic parasympathetic fibers, and the deep petrosal nerve which, representing the post-ganglionic sympathetic fibers.

What is the purpose of 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 maxillary nerve (branch of the trigeminal nerve, CN V) passes through this foramen.
