The muscle that rotates the eye medially is the
(a) Superior oblique
(b) Inferior rectus
(c) Medial rectus
(d) Lateral rectus

Guida verificata passo dopo passo

Step 1: Understand the function of each extraocular muscle listed in the options. The eye muscles control movements such as elevation, depression, abduction, adduction, and rotation.

Step 2: Recall that 'medial rotation' of the eye means turning the eye inward toward the nose, which is also called adduction.

Step 3: Identify the muscle responsible for adduction. The medial rectus muscle pulls the eye medially (toward the midline).

Step 4: Review the other muscles: the superior oblique primarily causes depression and intorsion (inward rotation), the inferior rectus causes depression and extorsion (outward rotation), and the lateral rectus causes abduction (moving the eye laterally).

Step 5: Conclude that the muscle that rotates the eye medially is the medial rectus, corresponding to option (c).

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Extraocular Muscles

Extraocular muscles control eye movements and include six muscles: four rectus muscles (superior, inferior, medial, lateral) and two oblique muscles (superior and inferior). Each muscle has a specific role in moving the eye in different directions.

Medial Rotation of the Eye

Medial rotation, or adduction, refers to moving the eye inward toward the nose. The muscle responsible for this movement pulls the eyeball medially, allowing the eyes to focus on objects close to the midline.

Function of the Medial Rectus Muscle

The medial rectus muscle is primarily responsible for adducting the eye, meaning it rotates the eye medially. It is innervated by the oculomotor nerve and plays a key role in coordinating binocular vision.
