It is one of six extraocular muscles that controsl the movements of the eye
Abducens
lateral rectus
"Linea semilunaris is the lateral edge of the rectus abdominis muscle that crosses the costal margin at the tip of the ninth costal cartilage." ("Laboratory exercises in anatomy and physiology with cat dissections/ R.Amitrano, GTortora)
The muscle is called an 'extraocular muscle', of which there are 6 - they are relatively small,incredible strong and efficient. They are : medial rectus; superior rectus; superior oblique; lateral rectus; inferior rectus and inferior oblique.
Rectus Abdominis
The abducens nerve (cranial nerve VI) controls the lateral rectus muscle of the eye, which is responsible for abducting (moving the eye away from the nose) the eye. Dysfunction of the abducens nerve can result in horizontal double vision (diplopia) and difficulty moving the affected eye laterally.
The inferior oblique, superior oblique, lateral rectus, and medial rectus are all used to look cross eyed
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)
An abducent nerve is a nerve which controls the lateral rectus muscle in the eye.
The lateral rectus muscle is controlled by cranial nerve VI, also known as the abducens nerve. This muscle is responsible for moving the eye outward, away from the nose.
The muscles are called the extraocular muscules, and they are the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique.
Skeletal muscle is the type that allows you to direct your eyeballs. Skeletal muscle is the only type that can be consciously controlled.
