Lesson Summary. In summary, skeletal muscles are attached to bones on each end by tendons. The origin is the fixed attachment, while the insertion moves with contraction. The action, or particular movement of a muscle, can be described relative to the joint or the body part moved.Groups of muscles are involved in most movements and names are used to describe the role of each muscle involved.esson Summary.

The most common complication of cataract surgery is clouding of the part of the lens covering (capsule) that remains after surgery, called posterior capsule opacification. If the cloudiness affects your vision, you may choose to have a laser surgery called Nd:YAG posterior capsulotomy to correct this problem.
phacoemulsification. a technique of cataract extraction, utilizing high-frequency ultrasonic vibrations to fragment the lens combined with controlled irrigation to maintain normal pressure in the anterior chamber, and suction to remove lens fragments and irrigating fluid.(fak'Å-Ä-mÅ­l'si-fi-kÄ'shÅ­n),hacÂ·oÂ·eÂ·mulÂ·siÂ·fiÂ·caÂ·tion. A method of emulsifying and aspirating a cataract with a low-frequency ultrasonic needle. /phacoÂ·emulÂ·siÂ·fiÂ·caÂ·tion/ (-Ä-mulâ³sÄ­-fÄ­-kaÂ´shun) a method of cataract extraction in which the lens is fragmented by ultrasonic vibrations and simultaneously irrigated and aspirated.
