Question: what is the origin and insertion of the vastus medialis muscle?
Answer: The vastus medialis muscle originates from a continuous line of attachment on the femur, which begins on the front and middle side (anteromedially) on the intertrochanteric line of the femur. ... The fibers converge onto the inner (medial) part of the quadriceps tendon and the inner (medial) border of the patella.
