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.
The neodymium:YAG (Nd:Yag) laser is used to create posterior capsulotomies for posterior capsule opacification. Posterior capsule opacification generally occurs following cataract surgery.Desired outcomes of use of the Nd:Yag laser are an increase in visual acuity and/or improvement in glare and contrast sensitivity.he neodymium:YAG (Nd:Yag) laser is used to create posterior capsulotomies for posterior capsule opacification.
