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.
Capsular thickening. The capsule is the outer bag of the natural lens that is left behind during surgery to hold the artificial lens or implant. Over time, in some patients, this outer shell becomes cloudy, a condition known as capsular thickening or secondary cataract.The patient will notice vision becoming blurred â just like it did with the original cataract.apsular opacification (secondary cataract) is treated using a YAG laser and this is a brief and painless out-patient procedure. The pupil will be dilated at the time and the laser makes a new clear pathway in the area of the pupil, allowing light to reach the back of the eye.
