  3. Superior oblique muscle - Wikipedia

    en.wikipedia.org/wiki/Superior_oblique_muscle

    The superior oblique muscle loops through a pulley-like structure (the trochlea of superior oblique) and inserts into the sclera on the posterotemporal surface of the eyeball. It is the pulley system that gives superior oblique its actions, causing depression of the eyeball despite being inserted on the superior surface. Superior oblique nerve

    en.wikipedia.org/wiki/Trochlea_of_superior_oblique

    The body of the superior oblique muscle is located behind the eyeball, but the tendon (redirected by the trochlea) approaches the eyeball from the front. The tendon attaches to the top (superior aspect) of the eyeball at an angle of 51 degrees concerning the primary position of the eye (looking straight forward).

    Located in the superior orbital fissure. Innervates the levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique, which collectively perform most eye movements. Also innervates the sphincter pupillae and the muscles of the ciliary body. IV Trochlear: Motor Dorsal aspect of Midbrain

  6. Eye movement - Wikipedia

    en.wikipedia.org/wiki/Eye_movement

    Six extraocular muscles facilitate eye movement. These muscles arise from the common tendinous ring (annulus of Zinn) in the orbit (eye cavity), and attach to the eyeball. The six muscles are the lateral, medial, inferior and superior recti muscles, and the inferior and superior oblique muscles. The muscles cause movement of the eyeball by ...

  7. Extraocular muscles - Wikipedia

    en.wikipedia.org/wiki/Extraocular_muscles

    Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye. The other muscle, the levator palpebrae superioris, controls eyelid elevation. The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction. [2]

  9. Trochlear nerve - Wikipedia

    en.wikipedia.org/wiki/Trochlear_nerve

    The trochlear nerve is tested by examining the action of its muscle, the superior oblique. When acting on its own this muscle depresses and abducts the eyeball. However, movements of the eye by the extraocular muscles are synergistic (working together). Therefore, the trochlear nerve is tested by asking the patient to look 'down and in' as the ...
