Linea aspera to head of fibula and lateral condyle of tibia.
The biceps femoris has its origin in the middle third of the linea aspera, lateral to the supracondylar ridge of the femur.
Head of fibula and lateral condyle of tibia.
Joining with the long head in the distal thigh, it attaches to the styloid process of the fibular head forming a semicircle around the lateral fibular collateral ligament. Remaining splits into three laminae. The intermediate lamina fuses with the fibular collateral ligament while the other two pass superficial and deep to the ligament to attach to the lateral condyle of the tibia. The Wellness Digest
