The muscles responsible for the eye include several types, each with a specific function.
According to the provided reference, there isn't one single muscle, but rather groups of muscles responsible for different functions of the eye:
- Extraocular Muscles: These muscles control the external movements of the eye.
- Intraocular Muscles: These muscles are responsible for pupil accommodation and reaction to light.
- Eyelid Muscles: These include protractors and retractors of the eyelids.
Therefore, the "muscle responsible for the eye" depends on the specific action you are referring to (movement, pupil control, or eyelid function).
