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]
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]
extraocular
Mammals have 7 extra-ocular muscles, but humans lack the M. retractor bulbi.
Myofibers in extraocular muscles are derived from mesoderm, whereas muscle connective tissue cells arise from neural crest.[PMID:16638982]
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.
