Musculus rectus superior

The video tutorial explains the rectus superior muscle, one of the six outer eye muscles responsible for eye movements such as adduction, internal rotation, and elevation. It distinguishes between adduction and internal rotation, describes the muscle's origin at the annulus tendinosis communis, and details its blood supply from the anterior ciliary artery. The tutorial also covers the nerve innervation by the oculomotor nerve and discusses the potential impact of orbital trauma on structures passing through the superior orbital fissure.

What is the significance of the annulus tendinosis communis in relation to the rectus superior muscle?
