Where is the pes anserine located and which muscles insert there?

The pes anserine, which means "goose's foot" in Latin due to its shape, is located on the medial aspect of the tibia, specifically just below the tibial tuberosity. The correct muscles that insert at this site are the gracilis, semitendinosus, and sartorius.

These three muscles originate from different areas of the pelvis and contribute to various functions, such as knee flexion and hip adduction. Their insertion at the pes anserine facilitates these movements and also plays a role in stabilizing the knee.

The other options describe locations and muscle insertions that do not accurately represent the anatomy of the pes anserine. For instance, the iliotibial band, mentioned in one option, is not associated with the pes anserine; instead, it inserts on the lateral aspect of the tibia. The reference to the medial condyle and the adductor muscles also misrepresents the anatomical positioning and muscle insertions related to the pes anserine. Distal attachments of the quadriceps muscles are associated with the patellar tendon rather than the pes anserine, highlighting the importance of understanding the distinct anatomical relationships among these structures.
