     vastus lateralis
     vastus intermedius
     vastus medialis
Example of formatting used in tables to denote muscles and muscle groups.

The following tables of muscles have seven columns:

Often, a muscle is divided into other muscles; for example, the quadriceps femoris muscle is further subdivided into the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis. In these cases, the name of the muscle group is italicized and the component muscles are indented. An example appears to the right.

For more information on many of the terms used within these tables, see anatomical terms of location, anatomical terms of motion, medical terminology, list of human anatomical features and outline of human anatomy.
