Which muscle originates from the greater trochanter of the femur?

• A. Tibialis Anterior
• B. Vastus Lateralis
• C. Gastrocnemius
• D. Soleus

Answer: (B)

Understanding where a muscle starts (its origin) helps explain how it moves the joint. The greater trochanter of the femur is a prominent attachment site for several hip muscles, and among the options, the one that has a proximal attachment there is a part of the quadriceps group known for attaching high on the femur. Vastus lateralis originates from the greater trochanter (as well as the lateral lip of the linea aspera), making it the muscle whose starting point is at that bony landmark. It then extends down to insert on the patella via the quadriceps tendon and ultimately on the tibial tuberosity through the patellar ligament. The other muscles listed do not originate from the greater trochanter: tibialis anterior comes from the tibia and interosseous membrane; gastrocnemius originates from the femoral condyles (posterior surfaces); soleus comes from the posterior surfaces of the tibia and fibula.
