All quadriceps heads originate from different points on the proximal femur, except the rectus
femoris which arises from the pelvis.

We also measured cross-sectional muscle fiber areas in quadriceps
femoris muscle of rapamycin - or vehicle - treated aged mice and corresponding young controls (16 - and 25 - month cohorts; Figure 4, G and H),
which showed the expected aging - associated decrease in cross-sectional muscle fiber area.
Seated leg curls will better target the inner side of the hamstrings,
which includes the semitendinosus and the semimembranosus, while the biceps
femoris (traditionally called the thigh biceps)
which has a somewhat different function from the previous two can be emphasized with lying leg curls.
The hamstring is actually comprised of three muscles: the semitendinosus, semimembranosus and biceps
femoris,
which are responsible for knee flexion and stabilization and hip extension.
Needless to say, if you want to properly develop your hamstrings, you need to make sure to include exercises
which target each one of these muscles, not just the biceps
femoris.

which is the bone on the inside of the lower leg; whereas, the biceps
femoris runs down to the fibula,
which is the bone on the outside of the lower leg.
It has three other muscles
which are called semitendinosus, semimembranosus, and biceps
femoris.
This important new study used the latest methods to determine the muscle fiber type of the biceps
femoris (long head),
which is the hamstring muscle that is most often injured during sprinting.
The patella is a sesamoid bone encapsulated within the patellar ligament,
which itself is the distal aspect of the quadriceps
femoris muscle tendon where it inserts onto the tibial tuberosity.
