The inferior rectus muscle is a small muscle located in the eye that works to move the eye downward and inward. There are several synonyms for this muscle, including the inferior oblique, which also assists in moving the eye downward, and the inferior rectus torsion muscle, which helps to rotate the eye outward when looking down. Other possible synonyms for the inferior rectus muscle may include the depressor muscle, the inferior rectus oblique muscle, or the inferior rectus medial rectus muscle, depending on the specific actions and variation of the muscle in different individuals. Despite varying names and functions, all of these muscles work together to help move and rotate the eye for clear vision and proper alignment.
