Musculus obliquus superior

The video tutorial covers the superior obliquus muscle of the eye, detailing its origin, function, innervation, and blood supply. It explains the muscle's role in eye movement, its attachment points, and how it is innervated by the trochlear nerve. The blood supply is provided by branches of the anterior ciliary artery. The tutorial emphasizes the unique aspects of the superior obliquus muscle, such as its oblique attachment and its role in stabilizing eye movements.

What is the origin of the superior obliquus muscle?

• From the optic nerve

• From the lateral rectus muscle

• From the NEOS communis

• From the inferior oblique muscle

Which movement is the superior obliquus muscle primarily responsible for when the eye is in a neutral position?

• Adduction

• Elevation

• Abduction

• Convergence

How does the superior obliquus muscle contribute to eye stability?

• By increasing tear production

• By improving color perception

• By preventing involuntary rotation

• By enhancing peripheral vision

Which nerve is responsible for the innervation of the superior obliquus muscle?

• Trochlear nerve

• Abducens nerve

• Optic nerve

• Oculomotor nerve

Through which artery does the superior obliquus muscle receive its blood supply?

• Central retinal artery

• Lacrimal artery

• Anterior ciliary artery

• Posterior ciliary artery
