Superior Rectus allows you to look Up & In, whiel the Superior Oblique allows you to look Up & Out.
A total of six muscle move each eyeball, 4 rectus muscels and 2 obliques. The superior, inferior, lateral and medial rectal muscle all pull the eye to be looking more in ther own direction. The superior oblique pulls the eye to look down and laterally and the inferior oblique pull the eye to look um and medialy.
The Medial Rectus.
The inferior oblique muscle, which is located in the anterior portion beneath the eye (hence the inferior in the name). Its full Latin name is obliquus oculi inferior.
Trochlear Nerve innervates Superior Oblique(extrinsic eye muscle)Oculomotor Nerve innervates Inferior Oblique, Superior Rectus, Inferior Rectus, and Medial Rectus (which are all extrinsic eye muscles) along with Ciliary Body, and the Iris (which are both intrinsic eye muscles)Abducens Nerve innervates Lateral Rectus(extrinsic eye muscle)
The Trochlea Nerve (cranial nerve 4) controls the superior oblique muscle of the eye. It turns the eye laterally and downwards.
Abducens
The optic nerve (purely sensory; carry afferent impulses for vision) Oculomotor (innervates four of the extrinsic eye muscles) Trochlear (innervates an extrinsic eye muscle that hooks through a pulley-shaped ligament in the orbit) Abducens (innervates the muscle that turns abducts the eyeball)
inferior oblique
supinator
pronator
The superior oblique muscle turns the eye inferiorly and medially. It is innervated by the trochlear nerve.
