Skeletal muscle derived from cranial mesoderm and controls eye movements.
Myofibers in extraocular muscles are derived from mesoderm, whereas muscle connective tissue cells arise from neural crest.[PMID:16638982]
todo - resolve discrepancies in which muscles are considered extra-ocular
Any of the six small muscles that control movement of the eyeball within the socket. [TFD][VHOG]
Muscles surrounding the eye (bulbus oculi) and having an effect on eye movements.[AAO]
BTO and MA consider this part of the eye; we follow them here (inferred from skeletal muscle). Not clear if omission from FMA is deliberate.

musculi externi bulbi oculi
The ability to rotate the eyeball is common to all vertebrates with well-developed eyes, regardless of the habitat in which they live, so these (extrinsic ocular) muscles tend to be conservative. They change little during the course of evolution.[well established][VHOG]
Mammals have 7 extra-ocular muscles, but humans lack the M. retractor bulbi.
