Muscle diagrams are a great way to get an overview of all of the muscles within a body region. Studying these is an ideal first step before moving onto the more advanced practices of muscle labeling and quizzes. If you're looking for a speedy way to learn muscle anatomy, look no further than our anatomy crash courses.

We’ve created muscle anatomy charts for every muscle containing region of the body: Each chart groups the muscles of that region into its component groups, making your revision a million times easier. For example, upper limb muscles are grouped by shoulder and arm, forearm and hand.

The illustration below shows some of the muscles of the lower extremity. Muscles that move the leg are located in the thigh region. The quadriceps femoris muscle group straightens the leg at the knee. The hamstrings are antagonists to the quadriceps femoris muscle group, which are used to flex the leg at the knee.

Anatomically, the leg is defined as the region of the lower limb below the knee. It consists of a posterior, anterior and lateral compartment. In accordance, the muscles of the leg are organized into three groups:
