The other day I was in for my annual eye exam. While I was waiting in the exam room, I studied a poster of the eye and its muscles. As you would assume, the eye has muscles attached to the eye at numerous points allowing full rotation and movement of the human eye. One muscle in particular caught my attention – the superior oblique. This muscle actually passes through a loop of bone to provide intorsion and abduction (no, I didn’t know that, the reference is below). As I looked at the phenomenon, I marveled at God’s divine plan. I believe in science and I believe that God can use anything to achieve His outcome. To simply deny that God created life and humans implies that science, which typically takes the path of least resistance, created a muscle that grows through a loop of bone that grows for this sole purpose – to provide ocular motion. To see an image of the muscle:

From the great wikipedia:“The superior oblique muscle, or obliquus oculi superior, is a fusiform muscle in the upper, medial side of the orbit whose primary action is intorsion and whose secondary actions are to abduct (laterally rotate) and depress the eyeball (i.e. it makes the eye move outward and downward). One of the extraocular muscles, the superior oblique is the only muscle innervated by the trochlear nerve. 

The primary action of the superior oblique muscle is intorsion; the secondary action is depression (primarily in the adducted position); the tertiary action is abduction. A brief survey of neurology and physiology texts and websites reveals much confusion about the role of the superior oblique muscle, with many sources claiming that its role is to move the eye towards the nose. In fact, because of its positioning, it is able to rotate the eye away from the nose so that when the eye is already adducted (looking directly “inwards”) its rotational action turns the pupil downwards to look towards the mouth, which many texts misinterpret as its primary action.

Man, science is amazing.
