Adductors

1 adductor longus

2 vastus medialis

3 gracilis

4 adductor magnus

5 obturator externus

This muscle is called:

1 adductor longus T2 vastus medialis F3 gracilis F4 adductor magnus F5 obturator externus F

This muscle is called:

1 it has a double innervation from the sciatic and femoral nerves

2 it is innervated by the obturator nerve

3 it is innervated by the common peroneal component of the sciatic nerve

4 it is attached proximally to the ischial tuberosity

5 it forms part of the floor of the femoral triangle

Concerning adductor magnus muscle:

1 it has a double innervation from the sciatic and femoral nerves F

2 it is innervated by the obturator nerve T3 it is innervated by the common peroneal component of the

sciatic nerve F4 it is attached proximally to the ischial tuberosity T5 it forms part of the floor of the femoral triangle F

Concerning adductor magnus muscle:

Adductor magnus has a double innervation from the sciatic and obturator nerves, not the femoral nerve.  Part of adductor magnus does in fact attach to the ischial tuberosity. This is known as the hamstring portion of adductor magnus. Adductor magnus forms part of the floor of the adductor canal, not the femoral triangle.

1 pectineus

2 adductor brevis

3 sartorius

4 obturator externus

5 adductor magnus

This muscle is called:

1 pectineus F2 adductor brevis T3 sartorius F4 obturator externus F5 adductor magnus F

This muscle is called:

1 it forms part of the floor of the femoral triangle

2 it forms the medial boundary of the femoral triangle

3 it contributes to the floor of the adductor canal

4 it is innervated by the obturator nerve

5 it arises from the pubic tubercle

Concerning adductor longus:

1 it forms part of the floor of the femoral triangle T

2 it forms the medial boundary of the femoral triangle T

3 it contributes to the floor of the adductor canal T

4 it is innervated by the obturator nerve T

5 it arises from the pubic tubercle F

Concerning adductor longus:

Since by definition the medial border of adductor longus forms the medial boundary of the femoral triangle, the adductor longus contributes to the floor of the femoral triangle. Distal to the apex of the femoral triangle the adductor longus contributes to the floor of the adductor canal. The origin of adductor longus is from the anterior surface of the pubic bone below the level of the pubic tubercle.

1 the long head of biceps femoris

2 gracilis

3 sartorius

4 vastus medialis

5 semitendinosus

This muscle is called:

1 the long head of biceps femoris F2 gracilis T3 sartorius F4 vastus medialis F5 semitendinosus F

This muscle is called:

1 it arises from the outer surface of the ischiopubic ramus

2 it is a flexor of the knee

3 it is innervated by the obturator nerve

4 it is innervated in part by the sciatic nerve

5 it inserts onto the posterior aspect of the medial tibial condyle

Concerning gracilis

1 it arises from the outer surface of the ischiopubic ramus T2 it is a flexor of the knee T3 it is innervated by the obturator nerve T4 it is innervated in part by the sciatic nerve F5 it inserts onto the posterior aspect of the medial tibial condyle F

Concerning gracilis

Gracilis is inserted onto the medial aspect of the upper end of the tibial shaft, alongside sartorius and semitendinosus.  The gracilis is innervated exclusively by the obturator nerve.

1 it has a dual nerve innervation from the femoral and obturator nerves

2 it lies deep to the adductor longus

3 it inserts into the lower third of the linea aspera of the femur

4 as well as adducting the thigh, it serves to flex the knee

5 it is straddled by the anterior and posterior divisions of the obturator nerve

Concerning adductor brevis:

1 it has a dual nerve innervation from the femoral and obturator nerves F2 it lies deep to the adductor longus T3 it inserts into the lower third of the linea aspera of the femur F4 as well as adducting the thigh, it serves to flex the knee F5 it is straddled by the anterior and posterior divisions of the obturator nerve T

Concerning adductor brevis:

Adductor brevis runs behind (ie; deep to) adductor longus, and is inserted into the upper part of the linea aspera. Adductor brevis is innervated exclusively by the obturator nerve. In fact the muscle lies between the anterior and posterior divisions of the obturator nerve.

1 its distal attachment is to the lateral femoral condyle

2 it is attached in part to the linea aspera of the femur

3 it is traversed by the femoral artery and vein

4 it is innervated by the saphenous nerve

5 it is an extensor of the hip joint

Concerning adductor magnus:

1 its distal attachment is to the lateral femoral condyle F

2 it is attached in part to the linea aspera of the femur T

3 it is traversed by the femoral artery and vein T

4 it is innervated by the saphenous nerve F

5 it is an extensor of the hip joint F

Concerning adductor magnus:

The distal attachment of adductor magnus is to the linea aspera, medial supracondylar ridge and adductor tubercle on the medial femoral condyle. The femoral artery and vein go through a natural opening in the adductor magnus tendon called the adductor hiatus. The hamstring part of adductor magnus is a weak extensor of the hip joint.

1 it lies posterior to adductor brevis

2 it lies posterior to the profunda femoris artery

3 it forms part of the floor of the adductor canal

4 it is a weak flexor of the knee joint

5 it is attached to the linea aspera of the femur

Concerning adductor longus:

1 it lies posterior to adductor brevis F

2 it lies posterior to the profunda femoris artery F

3 it forms part of the floor of the adductor canal T

4 it is a weak flexor of the knee joint F

5 it is attached to the linea aspera of the femur T

Concerning adductor longus:

Both adductor brevis and the profunda femoris artery lie posterior to the adductor longus muscle. The adductor longus does not cross the knee joint, and consequently has no action on the knee joint.

1 it enter the adductor compartment by going through the femoral canal

2 it enters the adductor compartment by traversing the lesser sciatic foramen

3 it has a root value of L2, L3 and L4

4 it provides motor innervation to obturator externus

5 it provides motor innervation to obturator internus

Concerning the obturator nerve:

1 it enter the adductor compartment by going through the femoral canal F

2 it enters the adductor compartment by traversing the lesser sciatic foramen

F

3 it has a root value of L2, L3 and L4 T

4 it provides motor innervation to obturator externus T

5 it provides motor innervation to obturator internus F

Concerning the obturator nerve:

The obturator nerve is a branch of the lumbar plexus and has a root value of L2, L3 and L4. It enters the adductor compartment of thigh by traversing the obturator foramen, not the femoral canal or lesser sciatic foramen!
