"Semitendinosus" Natural Recordings by Native Speakers
The semitendinosus is one of the three hamstring muscles in the thigh, along with the semimembranosus and the biceps femoris. It originates in the ischial tuberosity (the bony bump at the bottom of the pelvis) and Inserts into the medial (inner) head of the tibia (shinbone).
The semitendinosus helps to:
1. Extend the knee: The semitendinosus muscle helps to straighten the knee, a movement known as extension.
2. Flex the hip: The semitendinosus also helps to bend the hip joint, a movement known as hip flexion.
3. Rotate the tibia: The semitendinosus helps to rotate the tibia inward, a movement known as medial rotation.
The semitendinosus muscle is an important contributor to the balance and stability of the knee joint, and it also plays a role in weight-bearing activities and movements that involve the hip and knee joints.
