Structure
See also: Extraocular muscles
Innervation
As with most of the muscles of the orbit, it is innervated by the oculomotor nerve (Cranial Nerve III).
Function
See also: Eye movement
It depresses, adducts, and helps extort (rotate laterally) the eye.
The inferior rectus muscle is the only muscle that is capable of depressing the pupil when it is in a fully abducted position.[1]
