Question

3 multiple choice 1 point which of the following muscles is the only biarticular quadriceps muscle? vastus lateralis vastus medialis rectus femoris vastus intermedius clear my selection

Explanation:

The rectus femoris is a muscle of the quadriceps group. It originates from the ilium (hip bone) and inserts into the tibial tuberosity (via the patellar tendon). Since it crosses both the hip and knee joints, it is biarticular. The vastus lateralis, vastus medialis, and vastus intermedius originate from the femur and insert into the tibial tuberosity (via the patellar tendon), crossing only the knee joint, so they are monoarticular.

Answer:

Rectus femoris
