2/14/2012 Anatomy and Physiology Muscle Grip Strength Lab Report Introduction: Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their

up again. –With the ATP molecule in place on the myosin head and calcium ions present‚ the cycle can continue. The cells of our skeletal muscles are made up of complex proteins called myofibrils. These myofibrils are further divided into sections called sarcomeres. All of the exciting chemistry that creates muscle movement occurs here in the sarcomere. Each muscle has thousands of these sections‚ and they all contract together to produce movement. To understand what happens within each sarcomere

Thato’s muscle had remained unused for 6 weeks. Once the cast is removed and he steps down from the examination table‚ his muscle begins to contract. Due to this 6 week period of rest‚ the muscles initial strength of contraction may be significantly low as compared to its strength a few minutes later. The strength of contraction of his muscle increases to a plateau‚ which is termed the staircase effect. Due to his muscles low initial strength of contraction‚ Thato loses his balance and falls. 1
