Rectus femoris: origin

Anterior iliac spine - function: flex at hip joint and extend at knee joint

1

Quadriceps/Patellar tendon - common insertion of what thigh muscles?

Quadriceps femoris

4

Common insertion of Iliacus and Psoas muscles

Lesser trochanter of femur

5

Thigh has three compartments: if the anterior compartment were flexors then the medial compartment would be?

ADDUCTORS - posterior were extensors

7

Medial thigh compartments - adducts the thigh is innervated by what nerve?

Obturator nerve

8

All are medial thigh muscles except:
Adductor longus, Adductor brevis, Gracilis, Pectineus, Adductor magnus

Pectineus - anterior thigh muscle

9

Common insertion of adductor muscles

Linea aspera of femur

10

Adductor tubercle of femur is the insertion of hamstring part of

Adductor magnus - both has adductor and extensor function

11

Nerve blocked during s femoral vein catheterization

Genitofemoral nerve

12

Anterior thigh muscles : flexors of the thigh and extensors of the leg is innervated by?

Femoral nerve

13

Extensors of the thigh - posterior thigh muscles - flexor of the leg is innervated by?

Sciatic nerve

14

Common origin of hamstring muscles

Ischial tuberosity

15

Common origin of Gluteal muscles:

Outer surface of ilium

16

What is the superior border of the femoral triangle (contains nerve, artery and vein of femoral branch)

Inguinal ligament
Medial - adductor longus
Lateral - sartorius

17

Greater trochanter of femur is the common insertion for gluteal muscles except what muscles?

Gluteus maximus - gluteal tuberosity
Quadratus femoris - quadrate tubercle

18

Lumbar plexus formed within the ___muscle by the ventral rami of L1-L4

Psoas major muscles

19

Largest branch of lumbar plexus, lateral border of Psoas

Femoral nerve - L2, L3, L4 - supplies the muscles on the anterior thigh and skin on antero-medial aspect

20

Quadriceps femoris is composed of what?

Rectus femoris
Vastus lateralis
Vastus medialis
Vastus intermedius

21

Lumbosacral trunk is composed of

L4 joins L5

22

Hernial sac of a femoral hernia is located?

BELOW and LATERAL to pubic tubercle

23

Obturator nerve is from ___. Medial border of Psoas, supplies medial thigh muscles and skin on the medial aspect of the thigh

L2, L3 and L4

24

Sacral plexus lies on the posterior pelvic wall in front of what muscle?

Piriformis muscle

25

Sciatic nerve (L4-S3) leave the pelvis through ____ foramen

Greater Sciatic Foramen

26

Superior gluteal (L4-S1) innervates the ___ muscles

Gluteus medius/ Gluteus minimus

27

Inferior gluteal nerve (L5-S2) innervates the ___ muscle.

Gluteus maximus

28

Sacral plexus is formed by the anterior rami of ___

L4 and L5 and S1 - S4

29

Pudendal nerve is from?

S2, S3 and S4

30

Lesion: weakend abduction of thigh by gluteus medius, " waddling gait", sagging of pelvis on the unsupported limb, (+) Trendelenburg sign

Superior gluteal nerve injury

31

Patient had an accident resulting to weakness in the ability to laterally rotate and extend the thigh at hip joint. Has difficulty extending the thigh from flexed position: climbing stairs and rising from a chair. What lesion and muscle involved?

Inferior gluteal nerve injury - affecting the Gluteus maximus

32

Sciatic nerve lesions as a result of a posterior dislocation of the femur commonly compressed what roots of the sacral plexus?

L5 and S1 roots are commonly compressed - pain radiates into the L5 and S1 dermatomes of the leg and foot
