Anatomy of the Bony Orbit Insights and Key Structures

This video tutorial by AnatomyZone, in collaboration with teachmeanatomy.info, explores the anatomy of the bony orbit. It covers the structure, components, and contents of the bony orbit, including the bones forming its boundaries, the walls, and the associated structures like muscles, nerves, and blood vessels. The tutorial also explains the pathways and openings within the orbit, such as the optic canal and orbital fissures. Additional resources and 3D models are provided for further learning.

What is the shape of the bony orbit?

• Cuboidal

• Spherical

• Pyramidal

• Cylindrical

Which bone forms the superior border of the orbital rim?

• Sphenoid

• Frontal

• Zygomatic

• Maxilla

Which bones form the floor of the bony orbit?

• Frontal and Sphenoid

• Maxilla, Palatine, and Zygomatic

• Ethmoid and Lacrimal

• Zygomatic and Sphenoid

What is the primary function of the extraocular muscles?

• Move the eyeball and eyelid

• Protect the eyeball

• Supply blood to the eye

• Transmit nerve signals

Which cranial nerve is responsible for transmitting visual information?

• Optic

• Abducens

• Trochlear

• Oculomotor

Which artery primarily supplies blood to the eye?

• Ophthalmic artery

• Carotid artery

• Temporal artery

• Maxillary artery

What does the optic canal transmit?

• Maxillary nerve and veins

• Oculomotor nerve and veins

• Optic nerve and ophthalmic artery

• Trochlear nerve and arteries

Which structure separates the lateral wall of the orbit from the floor?

• Inferior orbital fissure
