MICROANATOMY

Detailed explanation-1: -These muscles are unique in that they do not originate from the common tendinous ring, have an angular attachment to the eyeball, and they attach to the posterior aspect of the eyeball. The superior oblique functions explicitly to move the eye in the down-and-out position and intort the eye.

Detailed explanation-2: -The cranial nerve, the spinal nerve CN IV and VI control the other two extraocular muscles, the superior oblique muscle and lateral rectus muscle, respectively.

Detailed explanation-3: -The trochlea of superior oblique is a pulley-like structure in the eye. The tendon of the superior oblique muscle passes through it. Situated on the superior nasal aspect of the frontal bone, it is the only cartilage found in the normal orbit. The word trochlea comes from the Greek word for pulley.

Detailed explanation-4: -The trochlear nerve, also known as cranial nerve 4 (CN IV), controls the superior oblique muscle in your eye. This muscle allows you to move your eyeball down and shift your gaze from side to side.

Detailed explanation-5: -Three cranial nerves are responsible for controlling the eye muscles. These are the third cranial nerve (oculomotor nerve), the fourth cranial nerve (trochlear nerve), and the sixth cranial nerve (abducens nerve). The secondary names of these nerves kind of give away what muscles they control.
