Gastrocnemius Muscle and Achilles Tendon Anatomy - Medical Illustration #2074429 (License: Personal Use)

The image displays a sagittal anatomical view of the posterior lower leg, clearly labeling the gastrocnemius muscle’s medial and lateral heads originating from the femur and converging distally. These muscles unite to form the thick Achilles (calcaneal) tendon, which inserts onto the posterior surface of the calcaneus, enabling plantarflexion of the foot. Blue and red arrows indicate muscle origin and tendon insertion points respectively.

Used in orthopedic, physiotherapy, and anatomy educational resources to explain calf musculature, tendon injuries (e.g., Achilles tendinitis or rupture), and biomechanics of walking/running. Matches user intent for learning, diagnosis support, or patient education.
