The muscle and myotendinous junction (MTJ) are most commonly injured in the young adult, as a result of indirect mechanisms such as overuse or stretching, direct impact (penetrating or nonpenetrating), or … Biomechanics of the skeletal muscles. A muscle consists of fibers of muscle cells surrounded by protective tissue, bundled together many more fibers, all surrounded in a thick protective tissue. A muscle uses ATP to contract and shorten, producing a force on the objects it is connected to. There are several types of muscle, which act on various parts of the body. Skeletal muscles are organized multinucleated myofibers, whose function is to generate length and velocity dependent forces for movement or stability. … Complex central and peripheral elements control the biomechanics of the lumbar spine and ensure optimal spinal loading in normal everyday life situations. The ACL provides approximately 85% of the total restraining force of anterior translation. Shoulder Joint Anatomy Overview Gross Anatomy. Skeletal muscle is the only organ of the muscular system.
