Where do hamstrings have their origin?
More specifically, it extends from the ischial tuberosity of bony pelvis to the proximal end of the tibia below medial condyle, where it inserts via the pes anserinus. Semitendinosus receives its innervation through the tibial division of sciatic nerve.

What is the origin and insertion of the biceps femoris?

Why are hamstrings called hamstrings?
The “ham” of “hamstring” comes from an Old Teutonic word “ham” meaning crooked. This is in reference to the crooked part of the leg, that is the knee. To “hamstring” someone is to cripple them. See Hamstring Injuries and the Hamstring Stretch to prevent hamstring injuries.

Where are hamstrings located?
The hamstring muscles are a group of three muscles that run along the back of your thigh from your hip to just below your knee. These muscles make it possible to extend your leg straight behind your body and to bend your knee.
Are hamstrings flexors or extensors?
This means that the hamstrings cross two joints, the hip and the knee. They are the primary flexors of the knee joint (meaning they bend the knee), as well as secondary hip extensors (meaning they help straighten the hip).
