Explanation:
Detailed explanation-1: -Contraction of the lateral rectus pulls the eye away from the nose (abduction or lateral movement).
Detailed explanation-2: -The lateral rectus muscle is an abductor and moves the eye laterally, and side to side along with the medial rectus, which is an adductor.
Detailed explanation-3: -The abducens nerve controls the lateral rectus muscle, which abducts the eye. Abducens nerve palsy causes an esotropia due to the unopposed action of the antagonistic medial rectus muscle. The affected eye turns medially and is unable to abduct properly.
