We will focus on that muscles that control the movement of the eye and its related structures. The first muscle of the orbit we’ll be talking about is the levator palpebrae superioris. As the name suggests, this is the muscle responsible for the lifting of the upper eyelid upon contraction. This muscle is innervated by the oculomotor nerve, also known as cranial nerve number three. It originates from the lesser wing of the sphenoid bone. The next muscle of the orbit we’ll be talking about in this video is the superior oblique muscle, which is innervated by the trochlear nerve - or cranial nerve number four. It has its origin from the body of the sphenoid bone, and passes through the trochlear, inserting in the posterolateral part of the sclera. The contraction of this muscle abducts, depresses, and medially rotates the eye.
