Definition[Bearbeiten]
The rectus lateralis muscle is a skeletal muscle of the outer eye musculature.
Course[Bearbeiten]
The origin of the rectus lateralis muscle is the annulus tendineus communis. After a straight course, the muscle attaches via the sclera to the lateral bulbus oculi, ventral to the equator bulbi.
Innervation[Bearbeiten]
The rectus lateralis muscle is innervated by the abducens nerve.
Blood supply[Bearbeiten]
The lacrimal artery, a branch of the ophthalmic artery, is responsible for the arterial blood supply.
Function[Bearbeiten]
The eyeball is rotated laterally (abduction) when the rectus lateralis muscle contracts.
