1 adductor brevis F

2 adductor longus F

3 adductor magnus T

4 sartorius F

5 quadriceps femoris F

Which one of these muscles is part-hamstring and part-adductor?

Adductor Magnus arises in part from the ischial tuberosity. This part is the hamstring component of the muscle.

1 it is innervated by both components (tibial and common peroneal) of the sciatic nerve

2 it is intimately related to the lateral collateral ligament of the knee joint

3 it has the sciatic nerve running deep to it

4 it has the posterior femoral cutaneous nerve running superficial to it

5 it is attached distally to the fibular head

Concerning biceps femoris:

1 it is innervated by both components (tibial and common peroneal) of the sciatic nerve T

2 it is intimately related to the lateral collateral ligament of the knee joint T

3 it has the sciatic nerve running deep to it T

4 it has the posterior femoral cutaneous nerve running superficial to it T

5 it is attached distally to the fibular head T

Concerning biceps femoris:

The biceps femoris flexes and laterally rotates the knee.  The long head of biceps femoris is innervated by the tibial component of the sciatic nerve while the short head receives its nerve supply from the common peroneal nerve.

1 it lies posterior to semimembranosus

2 it arises in common with quadratus femoris

3 it is innervated by the tibial component of the sciatic nerve

4 its distal attachment is to the posterior surface of the medial tibial condyle

5 it helps form the lower medial boundary of the popliteal fossa

Concerning the semitendinosus muscle:

1 it lies posterior to semimembranosus T

2 it arises in common with quadratus femoris F

3 it is innervated by the tibial component of the sciatic nerve T

4 its distal attachment is to the posterior surface of the medial tibial condyle F

5 it helps form the lower medial boundary of the popliteal fossa F

Concerning the semitendinosus muscle:

The distal attachment of semitendinosus is to the medial surface of the proximal end of the tibial shaft alongside the tendons of Gracilis and Sartorius (also known as the pes anserinus or the goose’s foot). Semitendinosus and semimembranosus together make up the upper medial boundary of the popliteal fossa.

1 short head of biceps femoris

2 adductor longus

3 semitendinosus

4 adductor brevis

5 long head of biceps femoris

The following muscles have an attachment to the linea aspera of the femur:

1 short head of biceps femoris T

2 adductor longus T

3 semitendinosus F

4 adductor brevis T

5 long head of biceps femoris F

The following muscles have an attachment to the linea aspera of the femur:

Semitendinosus and long head of biceps femoris are both true hamstrings. Their proximal attachments are thus to the ischial tuberosity. Neither has any attachment to the femur.

1 the short head of biceps femoris is supplied by the tibial component of the sciatic nerve

2 the long head of biceps femoris is supplied by the common peroneal component of the sciatic nerve

3 the semimembranosus is supplied by the tibial component of the sciatic nerve

4 adductor magnus is supplied by the tibial component of the sciatic nerve

5 adductor longus is supplied wholly by the obturator nerve

Concerning the motor innervation of the thigh musculature:

1 the short head of biceps femoris is supplied by the tibial component of the sciatic nerve F

2 the long head of biceps femoris is supplied by the common peroneal component of the sciatic nerve

F

3 the semimembranosus is supplied by the tibial component of the sciatic nerve T

4 adductor magnus is supplied by the tibial component of the sciatic nerve T

5 adductor longus is supplied wholly by the obturator nerve T

Concerning the motor innervation of the thigh musculature:

The tibial component of the sciatic nerve innervates the long head of biceps femoris while the common peroneal component supplies the short head. The tibial component of the sciatic nerve also innervates the semimembranosus and the hamstring part of adductor magnus.

1  the lateral intermuscular septum lies immediately behind the vastus lateralis muscle

2 the lateral intermuscular septum lies immediately in front of the biceps femoris muscle

3 the medial intermuscular septum separates the adductor magnus from the biceps femoris muscle

4 the biceps femoris has a dual innervation from the sciatic and obturator nerves

5 the biceps femoris muscle has no attachment to the femoral shaft

Concerning the posterior compartment of thigh:

1  the lateral intermuscular septum lies immediately behind the vastus lateralis muscle T

2 the lateral intermuscular septum lies immediately in front of the biceps femoris muscle T

3 the medial intermuscular septum separates the adductor magnus from the biceps femoris muscle F

4 the biceps femoris has a dual innervation from the sciatic and obturator nerves F

5 the biceps femoris muscle has no attachment to the femoral shaft F

Concerning the posterior compartment of thigh:

The lateral intermuscular septum is a tough fibrous sheet that extends from the deep surface of the fascia lata to the posterior aspect of the femoral shaft. It separates the vastus lateralis from the biceps femoris, lying immediately posterior to the former and immediately anterior to the latter. The medial intermuscular septum is much thinner and much less prominent than the lateral intermuscular septum, and lies between vastus medialis and the adductors. Biceps femoris is innervated by both components of the sciatic nerve but not by the obturator nerve. The short head of biceps femoris takes origin from the linea aspera on the posterior aspect of the femoral shaft.
