It is a thin plane of muscular and tendinous fibers, situated upon the inner surface of the front wall of the chest.

The muscular fibers may be grouped according to their origins into three parts:

Santorini's muscle: Bundle of muscular fibers that draw the angle of the mouth laterally.

The iris is made up of muscular fibers that control the amount of light entering the pupil so that we can see clearly.

Well-preserved specimens show evidence of muscular fibers in the mantle, indicating that they were powerful swimmers like modern squids.

Well preserved specimens have even retained evidence of strong muscular fibers in the mantle, indicating that they were powerful swimmers like modern squids.

For example, the type of muscular fiber you're made of will help in determining the best kind of exercise for you.

If this is not possible, the most common procedure is to create a small pocket of muscle, tissue at least 2 cm deep by separating the muscular fibers.

Microscopic stains of skeletal and cardiac muscular fibers to show striations.

The calcium concentration in sarcoplasma is also a special element of the muscular fiber by means of which the contractions takes place and regulates.
