What muscle roles your eye counter clockwise?
The primary muscle responsible for moving the eye counterclockwise is the superior oblique muscle, which is innervated by the trochlear nerve (cranial nerve IV). Additionally, the lateral rectus muscle, innervated by the abducens nerve (cranial nerve VI), assists in this movement by pulling the eye outward. Together, these muscles coordinate to achieve the desired counterclockwise rotation of the eye.
What cranial nerve is the superior rectus?
The superior rectus muscle is innervated by the oculomotor nerve, which is cranial nerve III. This muscle is responsible for elevating the eye and assisting in adduction and medial rotation. Dysfunction of the oculomotor nerve can lead to issues with eye movement, including difficulty in elevating the eye.

The primary muscles involved in torticollis are?
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
What cranial nerve involved while raising eye lids and focusing the lens of the eye for accommodation?
The cranial nerve involved in raising the eyelids is the oculomotor nerve (cranial nerve III). For focusing the lens of the eye for accommodation, the oculomotor nerve controls the ciliary muscle.
Which muscles are involved in shoulder external rotation?
The muscles involved in shoulder external rotation are the Infraspinatus and Teres Minor.
The infraspinatus muscle is a muscle that moves the?
lateral rotation of humerus (upper arm)
What does the inferior oblique muscle of the eye do?
The inferior oblique muscle of the eye, abducts, elevates and laterally rotates the eye
