Back

The gastrocnemius is a two-headed muscle that crosses both the knee and ankle joints, while the soleus is a single-headed muscle that only crosses the ankle joint.

Front

What is the origin of the biceps femoris muscle?

Back

The biceps femoris muscle originates from the ischial tuberosity (long head) and the linea aspera of the femur (short head).

Front

What is the insertion point of the gastrocnemius muscle?

Back

The gastrocnemius muscle inserts into the calcaneus via the Achilles tendon.

Front

What movements are facilitated by the vastus lateralis muscle?

Back
