Muscle fibers in adult rat EOM show unique metabolic properties, not seen in other skeletal muscles, covering their extraordinary functional demands. It can be speculated that the EOM embedded within the orbit material do not need to perform high force and therefore they could develop extensive systems ensuring them both fatigue resistance (many mitochondria) and fast contraction with high mATPase activity (a well developed sarcotubular system)
