Structures Passing Through Foramina in the Cranial Fossa and Face

Flashcards summarizing key anatomical structures and their corresponding foramina as discussed in the lecture notes.

What nerve passes through the cribriform plate of the ethmoid bone?

CN I (Olfactory Nerves)

Which canal transmits the optic nerve and ophthalmic artery?

Optic Canal (Foramen)

What nerves pass through the Superior Orbital Fissure?

CN III (Oculomotor N.), CN IV (Trochlear N.), CN V(1) (Ophthalmic Division of Trigeminal N.), CN VI (Abducens N.), and Ophthalmic Vein.

Which foramen carries the Maxillary Division of the Trigeminal Nerve?

Foramen Rotundum, which transmits CN V(2).

Which foramen allows the Mandibular Division of the Trigeminal Nerve to pass?

Foramen Ovale, transmitting CN V(3).

What structures travel past the Foramen Lacerum but do not pass through it?

Internal Carotid Artery and Sympathetic Plexus.

Which arteries and veins pass through the Foramen Spinosum?

Middle Meningeal Artery and Vein.

What structures pass through the Internal Acoustic Meatus?

CN VII (Facial N.) and CN VIII (Vestibulocochlear N.).

Which canal transmits the Hypoglossal Nerve?

Hypoglossal Canal.

What structures pass through the Foramen Magnum?

Medulla Oblongata, Spinal cord and its meninges, Vertebral Arteries, and Spinal root of Spinal Accessory N.

What nerve passes through the Supraorbital foramen?

Supraorbital N. (a branch of CN V(1)).

Which nerve is associated with the Infraorbital foramen?

Infraorbital N. (a branch of CN V(2)).

What nerve passes through the Mandibular foramen and exits through the Mental foramen?

Inferior Alveolar N. (a branch of CN V(3)).
