Which muscles are considered eye adductors?

  1. Superior oblique, Inferior oblique, Lateral rectus

  2. Superior rectus, Inferior rectus, Medial rectus

  3. Scleral muscle, Pupillary sphincter, Ciliary muscle

  4. Superior rectus, Inferior oblique, Medial oblique

The correct answer is: Superior rectus, Inferior rectus, Medial rectus

The correct answer is B. The muscles that are considered eye adductors are the Superior rectus, Inferior rectus, and Medial rectus muscles. These muscles work together to move the eye inward towards the nose, allowing for convergence of binocular vision. Options A, C, and D are incorrect: - Option A includes the Superior oblique, Inferior oblique, and Lateral rectus muscles, which are not eye adductors but rather are involved in other eye movements such as elevation, depression, and abduction respectively. - Option C includes the Scleral muscle, Pupillary sphincter, and Ciliary muscle, which are not primarily responsible for eye adduction. - Option D includes the Superior rectus, Inferior oblique, and Medial oblique muscles. While the Superior rectus and Inferior oblique muscles are included in the correct answer, the Medial oblique muscle does not play a role in eye adduction.
