Identify and name the cranial nerves responsible for eye movement. Indicate the function of each cranial nerve identified
What will be an ideal response?
The oculomotor nerve (III), trochlear nerve (IV), and abducens nerve (VI) are the three pairs of cranial nerves that control eye movement. The oculomotor nerve innervates the medial rectus, superior rectus, inferior rectus, and inferior oblique muscles. These muscles are responsible for moving the eye superiorly, medially, inferiorly, and superolaterally. The trochlear nerve innervates the superior oblique muscle of each eye which allows for medial and inferior eye movement. The abducens nerve innervates the lateral rectus muscle. This muscle abducts the gaze when it turns the eye laterally.
