Which of the below statements is incorrect about the gastrocnemius?

Question

To tackle the question, I’ll review each statement in the context of the gastrocnemius muscle’s anatomy and actions.
Option 1: 'It is superficial to the soleus' — This is true. The gastrocnemius lies on top of the deeper soleus in the posterior compartment of the leg, making it superficially located relative to the soleus.
Option 2: 'It is located on the anterior surface of the leg' — This is false. The gastrocnemius is part of the posterior (calf) compartment and lies on the back of the leg, not the anterior surface. Descriptions placing it anteriorly misidentify its location.
Option 3: 'Is responsible for flexion/plantarflexion of the foot' — This is true. The gastrocnemius actively contributes to plantarflexion of the foot at the ankle (and also assists with knee flexion due to crossing the knee joint).
Option 4: 'Distally attaches to the calcaneus' — This is true. The gastrocnemius (via the Achilles tendon) inserts on the calcaneal tuber, forming part of the Achilles tendon complex.
Option 5: 'Proximally attaches to the condyles of the femur' — This is true. The gastrocnemius has heads that originate from the femoral condyles (medial and lateral), near the knee joint.
In summary, the only statement that contradicts established anatomy is Option 2, which incorrectly places the gastrocnemius on the anterior surface of the leg; all other statements align with its posterior leg location, lateral/medial origins from the femoral condyles, distal calcaneal insertion via the Achilles tendon, and role in plantarflexion (and knee flexion).
