Every fibre of the muscle is approximately forty millimeter in length and is made up of a number of very small strands which are known as fibrils. These fibres are extremely slender, so much so that one square centimeter of a muscle contains in it up to one million fibres.
Every motion in any part of the body comes from the work of muscles. If a person merely bends a finger, the action comes from the muscles. Although the movement is very slight, it is brought about by the working together of muscles; with bones. Thus the muscles tend to make the parts of the body work together like the parts of a machine. How the muscles work. The greater part of a muscle is made up of tissues that expand and contract like rubber. At each end of every muscle is a tendon. This is a very strong tissue used to fasten the muscle to other parts of the body. It does not stretch. Often a tendon fastens a muscle to a bone. For example, the muscle at the front of the upper part of the arm, known as the biceps, is fastened by a tendon to the bones of the lower part of the arm just below the elbow.
