Question

What do all four quadriceps join to form? What does it contain?

a) They join to form the patellar ligament, which contains the patella (kneecap).
b) They join to form the ITB (iliotibial band), which contains the tensor fasciae latae.
c) They join to form the adductor magnus tendon, which contains the adductor muscles.
d) They join to form the quadratus femoris tendon, which contains the quadratus femoris muscle.

Answer 1

The four quadriceps muscles join to form the quadriceps tendon, which contains the patella and extends as the patellar ligament attaching to the tibial tuberosity.

Step-by-step explanation:

All four quadriceps muscles join to form the quadriceps tendon (also known as the patellar tendon), which inserts into the patella (kneecap) and continues below as the patellar ligament.

This tendon-ligament complex serves two major functions: it enables the quadriceps femoris muscle group to extend the knee joint, and it provides critical support and stabilization for the knee, acting as a 'dynamic ligament.' The correct answer to the question of what all four quadriceps join to form and what it contains is: (a) They join to form the patellar ligament, which contains the patella (kneecap).
