Muscle Anatomy Mock Questions: Muscles of the Legs

This blog will test your knowledge of the Muscles of the leg with TEN Muscle Anatomy Mock Questions, mapped to your Level 2 and 3 Anatomy exam.

You’ll discover:

  • The information you need to know about the Quadriceps, Hamstrings, Gastrocnemius, Adductors, and Abductors
  • A summary of all muscles of the legs
  • TEN Muscle Anatomy Mock Questions and answers to test your knowledge

The majority of muscles in the leg are considered long muscles, in that they stretch great distances.

As these muscles contract and relax, they move skeletal bones to create movement of the body.

Smaller muscles help the larger muscles, stabilize joints, help rotate joints, and facilitate other fine-tuned movements.

The largest muscle masses in the leg are present in the thigh and the calf.

Quadriceps Muscles:

The muscles that make up the quadriceps are the strongest of all muscles in the body. These four muscles at the front of the thigh are the major extensors (help to extend the leg straight) of the knee.

They are:

  • Vastus lateralis, 
  • Vastus medialis, 
  • Vastus intermedius, 
  • Rectus femoris

For the Level 2 Anatomy exam you need to know the names of all four muscles within the Quadriceps, the muscle action and location. At level 3 you will need to know the detailed origins and insertions.

Each of the Quadricep muscles have different origin points. However, they all cross the knee and insert on the tibia. They all have main joint action of Knee extension.

The Rectus Femoris crosses the Hip and the Knee, originating on the Anterior Inferior Iliac Spine (front of the pelvis). This means that the Rectus Femoris also create Hip Flexion during concentric contraction.

Hamstring Muscles:

The hamstrings are three muscles at the back of the thigh that affect hip and knee movement. They are:

  • Biceps femoris, 
  • Semimembranosus, 
  • Semitendinosus

They ALL originate on the Ischium (sits bones) and attach below the knee.
The Biceps femoris inserts on the Fibula and the other two muscles insert onto the Tibia.

During concentric contraction the hamstrings main joint actions are extension of the hip and flexion of the knee

Calf Muscles:

The calf muscles are pivotal to movement of the ankle, foot, and toes. Some of the major muscles of the calf include:

  • Gastrocnemius (calf muscle)
  • Soleus

Possibly the most important tendon in terms of mobility is the Achilles tendon. This important tendon in the back of the calf and ankle connects the plantaris, gastrocnemius, and soleus muscles to the heel bone. It stores the elastic energy needed for running, jumping, and other physical activity.

It is important to know that hte Gastrocnemius crosses both the Knee and the ankle, whereas the soleus only crosses the ankle.

The main action caused by these two muscles is plantarflexion of the ankle (pointing your toes away from the nose).

The antagonistic muscle to this would be the Anterior Tibialis in the front of the shin, which created Dorsiflexion at the ankle (toes to nose)

Adductors and Abductors:

The Adductors are responsible for drawing the leg into the midline, and make up the muscles of the inner thigh.

The Adductor Group is made up of Five muscles:

  • Adductor Magnus
  • Adductor Longus
  • Adductor Brevis
  • Pectineus
  • Gracilis

Learn more about the 5 adductor muscles HERE

The Adductors are the antagonists to the Abductor Muscles which spread across the outside of the bum and upper thigh. These are responsible for abducting the hip ( taking the leg away from the midline), and externally rotating the hip.

The Abductor group includes:

  • Gluteus Minimus
  • Gluteus Medius
  • Tensor Fascia Latae

In summary

  • The Quadriceps are on the front of the thigh and create Knee Extension
  • The Hamstrings are on the back of the thigh and create Knee Flexion
  • The Adductors are on the inside of the thigh and create Hip Adduction
  • The Abductors are on the outside of the hip and create Hip Abduction
