Posterior Thigh Muscles Flashcards
Posterior thigh muscles AKA
hamstrings
List the posterior thigh muscles: from lateral to medial
Biceps femoris- short and long head
Semimembranosus
Semitendinosus
Biceps femoris long head
Originates on the ischial tuberosity*
Both heads of biceps femoris insert on the fibular head, which allows them to laterally rotate the leg.
Biceps femoris short head
Originates on the linea aspera* of
the femur. Both heads of biceps femoris insert on the fibular head, which allows them to laterally rotate the leg.
Semimembranosus and semitendinosus
Originate on the ischial tuberosity* Insert on the medial tibial condyle,*
which allows them to medially rotate the leg.
• Semitendinosus lies superficial to semimembranosus.
• Semitendinosus is relatively thin, and terminates in a long cord-like tendon.
• Semimembranosus is relatively wide, and terminates in a flat, membranous tendon.
