Question

Eye ball is moved in the orbit by

• A. Four rectus and two oblique muscles
• B. Ciliary muscles
• C. Suspensory ligaments and ciliary muscles
• D. Three circular and four oblique muscles

Answer 1

Answer: (A)

Four rectus and two oblique muscles

The orbits or the eye sockets have six muscles with the help of which the eye is attached to the orbit and moves in it. These muscles are extraocular muscles. Four of these six extraocular muscles control the movements of eye in up, down, right and left directions. These four muscles are lateral, medial, inferior and superior rectus muscles. The rest two muscles adjust the movements of eye accordingly. These two muscles are inferior and superior oblique muscles.

Hence, the eye ball moves in the orbit by four rectus and two oblique muscles.

So, the correct answer is 'Four rectus and two oblique muscles'.
