Treating Trigger Points in Short Head Biceps Femoris - Stuart Hinds

 

What are the Hamstrings?

The hamstrings consist of three muscles. From medial to lateral they are the semimembranosus, semitendinosus, and biceps femoris. 

Origin

Ischial tuberosity (sitting bone). Biceps femoris also originates from back of femur.

Insertion

Semimembranosus: back of medial condyle of tibia (upper side part of tibia).
Semitendinosus: upper medial surface of shaft of tibia. Biceps femoris: lateral side of head of bula. Lateral condyle of tibia.

 

 

Action

Flex knee joint. Extend hip joint. Semimembranosus and semitendinosus also medially rotate (turn in) lower leg when knee is flexed. 
Biceps femoris laterally rotates (turns out) lower leg when knee is flexed.

Antagonists: quadriceps.

Nerve

Branches of sciatic nerve, L4, 5, S1, 2, 3.

Basic Functional Movement

During running, the hamstrings slow down the leg at the end of its forward swing and prevents the trunk from flexing at the hip joint.
