Muscle that does not arises from the common tendinous ring at the apex of orbit is?
The four recti arise from a common annular tendon or tendinous ring of zinn. This ring is attached to the orbital surface of the apex of the orbit. It encloses the optic canal and the middle pa of the superior orbital fissure.The lateral rectus has an additional small tendinous head which arises from the orbital surface of the greater wing of the sphenoid bone lateral to the tendinous ring. The inferior oblique arises from the orbital surface of the maxilla, lateral to the lacrimal groove. The muscle is situated near the anterior margin of the orbit.
