Is it possible to tear your quad muscle How can i know?
Quadriceps muscle is one of the strongest muscle of the body, but yes it can tear.

The patella is the round bone on the anterior of the knee. You can palpate the surface of the knee and you can gently shift the patella bone side to side. The insertion of the patella bone is quadricep ligament which attaches to the proximal end of the tibia. The origin of the patella is the quadricep tendon. The quadriceps consist of four muscles: rectus femoris, vastus intermedius, vastus medialis, and the vastus lateralis.
What kind of bone is the patella?
The patella, also known as the kneecap, is a sesamoid bone. Sesamoid bones are bones that are embedded within tendons and provide protection and mechanical advantage to that tendon. The patella is located within the quadriceps tendon and acts as a fulcrum to increase the leverage of the quadriceps muscles during knee extension.
What is Infrapatellar Tendon?
Infrapatellar tendon is the tendon below the knee
What are the effector muscles involved in a knee-jerk?
