Question: 1 / 400

Which muscle moves the eye inward?

The outer layer of the cornea

The type of corneal astigmatism with non-90-degree meridians

Medial rectus muscle

The muscle that moves the eye inward is known as the medial rectus muscle. This muscle is responsible for adduction of the eye, which means it pulls the eyeball toward the nose. Eye movements are controlled by several muscles, and the medial rectus is one of the extraocular muscles directly involved in coordinating eye position and movement.

In contrast, the other options provide different types of information not relevant to eye movements. The outer layer of the cornea refers to the structure of the eye but does not pertain to its muscle action. Corneal astigmatism is a condition related to the shape of the cornea affecting vision, and the displacement of light rays is linked to optics rather than muscle function. Thus, the correct answer clearly identifies the muscle responsible for inward eye movement, which is essential knowledge in the field of optics and ocular anatomy.
