quadriceps :)
These muscles all have a ligament of insertion which is called the patellar ligament. This ligament inserts to the tibial tuberosity.
The Quadriceps
Skeletal muscles work together or in opposition Muscles only pull (never push) As muscles shorten, the insertion generally moves toward the origin Whatever a muscle (or group of muscles) does, another muscle (or group) "undoes"
hamstring group is the primary muscle group for flexing the knee
Chin-ups, just as most exercises use a primary & secondary muscle group. The primary muscle group would be the back (or latissimus dorsi). This is what helps to give that "V" - shape in the torso area. (along with slimming down the torso area, of course) The secondary muscle group would be the biceps. Depending on your grip position, you can focus either more on your "lats", or arms.

Common Cause
Cardiac muscle is a tissue. It's a group of cells working together for a common function.
The general name for the group is hamstring. The technical names of the two primary muscles are semitendinosus and semimembranosus.
The Agonist muscle. In contrast, the muscle group that has passive action(the muscle being stretched) is called the antagonis muscle. For example, when doing a bicep curl. Your biceps are the agonists and your triceps would be the antagonists.
The quadriceps muscle goes over the patella. The patella is encased in the quadriceps tendon. This tendon inserts on the tibia at the tibial tuberosity. Other muscles from the thigh have tendons which go underneath the patella.
