Options:
explanation: The image shows a close view of the inside of the bony orbit on the left side. The blue arrow indicates the superior orbital fissure, which is a triangular opening located at the apex of the orbit in between the greater and the lesser wings of the sphenoid bone, lateral to the optic canal. The ophthalmic branch of the trigeminal nerve (CN V1) is one of the nerves that passes through the superior orbital fissure. Other contents of the superior orbital fissure include: oculomotor nerve (CN III), trochlear nerve (CN IV), abducens nerve (CN VI), superior ophthalmic vein.
name: Allows the passage of the ophthalmic branch of the trigeminal nerve (CN V)
label: a
answer: yes
explanation: The image shows a close view of the inside of the bony orbit on the left side. The blue arrow indicates the superior orbital fissure, which is a triangular opening located at the apex of the orbit in between the greater and the lesser wings of the sphenoid bone, lateral to the optic canal. The optic nerve (CN II) passes through the optic canal which is located medial to the superior orbital fissure and which is visible in the image.
name: Allows the passage of the optic nerve (CN II)
label: b
answer: no
explanation: The image shows a close view of the inside of the bony orbit on the left side. The blue arrow indicates the superior orbital fissure, which is a triangular opening located at the apex of the orbit in between the greater and the lesser wings of the sphenoid bone, lateral to the optic canal. The maxillary branch of the trigeminal nerve (CN V2) passes through the inferior orbital fissure, the space in between the lateral wall of the orbit and the floor of the orbit, inferior to the area indicated by the blue arrow, which is the superior orbital fissure.
name: Allows the passage of the maxillary branch of the trigeminal nerve (CN V)
label: d
answer: no
explanation: The image shows a close view of the inside of the bony orbit on the left side. The blue arrow indicates the superior orbital fissure, which is a triangular opening located at the apex of the orbit in between the greater and the lesser wings of the sphenoid bone, lateral to the optic canal. The ophthalmic artery passes, together with the optic nerve, through the optic canal, which is located medial to the superior orbital fissure and which is visible in the image.
name: Allows the passage of the ophthalmic artery
label: c
answer: no
explanation: The image shows a close view of the inside of the bony orbit on the left side. The blue arrow indicates the superior orbital fissure, which is a triangular opening located at the apex of the orbit in between the greater and the lesser wings of the sphenoid bone, lateral to the optic canal. The inferior ophthalmic vein passes through the inferior orbital fissure, the space in between the lateral wall of the orbit and the floor of the orbit, inferior to the area indicated by the blue arrow, which is the superior orbital fissure.
name: Allows the passage of the inferior ophthalmic vein
label: e
answer: no

Correct answer: a
