Superior oblique muscle

This tutorial explores the superior oblique muscle of the eye, covering its origin, insertion, function, innervation, and blood supply. The muscle is one of the six extraocular muscles, specifically an oblique muscle, which influences eye movements. It originates from the annulus of Zin and inserts onto the eye's posterior superior lateral surface. The muscle is responsible for abduction, intorsion, and depression of the eye, providing stability by counteracting head movements. It is innervated by the trochlear nerve and receives blood supply from branches of the anterior ciliary arteries.

How does the superior oblique muscle contribute to eye stability?
