- Semitendinosus
- Semimembranosus

ATTACHMENTS:

ACTIONS:
- Flexes the leg at the knee joint.
- Extends the thigh at the hip joint.
- Posteriorly tilts the pelvis at the hip joint.
- Medially rotates the leg at the knee joint.
NOTES:
- The semitendinosus is named for its long distal tendon.
- The semitendinosus is one of three muscles that attach into the pes anserine tendon (the other two are gracilis and sartorius). Pes anserine literally means goose foot.
