Verified step by step guidance

Understand the function of the rectus muscles: The rectus muscles are extraocular muscles that control the movement of the eye. Each muscle has a specific action depending on its orientation and attachment to the eyeball.

Identify the role of the superior rectus muscle: The superior rectus muscle is responsible for elevating the eye (raising it upward) when the eye is in a neutral position. It also contributes to slight inward rotation (adduction) and intorsion (rotation of the top of the eye toward the nose).

Compare the functions of the other rectus muscles: The lateral rectus moves the eye outward (abduction), the medial rectus moves the eye inward (adduction), and the inferior rectus moves the eye downward (depression) while also contributing to extorsion (rotation of the top of the eye away from the nose).

Relate the action of the superior rectus to the question: Since the question asks which rectus muscle raises the eye, the superior rectus is the correct answer based on its primary function of elevating the eye.

Summarize the reasoning: The superior rectus muscle is anatomically positioned and functionally designed to raise the eye, making it the correct choice among the options provided.
