What is the origin and insertion of the Biceps Femoris - Long Head?
|
Origin: Ischial tuberosity of the pelvis, part of the sacrotuberous ligament.
Insertion: Head of the fibula. |
|
What is the isolated function of the Biceps Femoris - Long Head?
|
Concentrically accelerates knee flexion and hip extension.
Tibial external rotation. |
|
What is the integrated function of the Biceps Femoris - Long Head?
|
*Eccentrically decelerates knee extension.
*Eccentrically decelerates hip flexion. *Eccentrically decelerates tibial internal rotation at mid-stance of the gait cycle. *Isometrically stabilizes the lumbo-pelvic-hip complex and knee. |
|
