In addition to muscle cells, a muscle is built up of a number of other cell types and tissues. The following chapter is designated to describe and discuss basic knowledge about the anatomy and physiology of the human skeletal muscles in comparison with the skeletal muscle of other species....
which essentially moves the skeleton, a skeletal muscle must also be attached to a fixed part of the skeleton. The moveable end of the muscle that attaches to the bone being pulled is called the muscle’sinsertion, and the end of the muscle attached to a fixed (stabilized) bone is called...

Factors to freemovementof the shoulder girdle.Each shoulder girdle attaches to the axial skeleton at only one point- thesternoclavicular joint; the loose attachment of the scapula allows it to slide back and forth against the thorax as muscles act; and, the glenoid cavity is shallow, and the...
During a clinical conference, you are asked to discuss skeletal muscle anatomy and physiology. Which of the following best describes histologic features of a “motor unit”? A. A single axonal branch and the muscle fibers it innervates B. A single nerve axon and the muscle fiber(s) ...
Learn about the major skeletal muscle functions. Deepen your knowledge of the structure of skeletal muscle, the characteristics of skeletal muscle,...
and support proteins. The arrangement of actin and myosin gives skeletal muscle its microscopic striated appearance and creates functional units called sarcomeres. When viewed under electron microscopy, sarcomeres are arranged longitudinally and include the M line, Z disk, H band, A band, and I ba...
Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilage of your skeletal system compose the scaffold that supports the rest of your body. Without the skeletal system, you would be a limp mass of organs, muscle, and skin. ...
