Flashcards in Hip & Thigh --> Bones and Muscles Deck (27):
1

what si the location of the lesser trochanter of the femur?

posteromedial

2

where is the intertrochanteric crest of the femur located?

posteriorly

3

the linea aspera is located on the ---1--- surface of the femur and distally divides into the ----2----

1 posterior
2 suprachondylar lines

4

what do the suprachondylar lines delineate?

the site of insertion of the popliteal muscle

5

what are the flexors of the hip and where do they arise from?

Psoas Major
Iliacus
from the posterior abdominal wall

6

what are the 3 main compartments of the thigh?

Anterior (extensors) occupies ~60%
Medial (adductors)
Posterior (flexors)

7

what is the fascia lata and what is its function?

investor of the thigh
limits bulging of muscles and works as a venous pump

8

what is the iliotibial tract?

lateral thickening of the fascia late, common aponeurotic tendon of insertion of Gluteus Maximus and Tensor of the Fascia Lata

9

what is the main function of Gluteus Maximus?

inserts into the lateral condyle of the tibia causes lateral rotation and extension of the hip
MAJOR FUNCTION is to extend the hip from sitting down

10

what is the main function of the tensor of the facia lata?

lateral side of the proximal part of the thigh
flexes and abducts and medially rotates the hip

11

what are the site of insertion of Gluteus Medius and Minimus? and what is their function?

Greater Trochanter
Abduction and Medial Rotation AND maintenance of the hip at coronal plane during swing phase

12

what muscle that comes from the pelvic region hast 2 gamely with them?

Obturator Internus

13

what are the main muscles that cause lateral rotation of the hip?

piriformis
obturator internus and gemeli
Quadratus femoris
Obturator Externus

14

what are all the muscles of the gluteal region?

GM
Gm and gm
piriformis
obturator internus and gemeli
Quadratus femoris

15

what are the muscles above Sartorius? (L-M)

Iliopsoas
Pectineus
Adductor Longus
Gracilis

16

what are the main muscles of the anterior compartment of the hip?

Iliopsoas
Pectineus
Quadriceps Femoris

17

what is the main function of iliopsoas?

Flexes the truck over the hip/Lifts leg
MAINTAINS LUMBAR LORDOSIS

18

what is the action of pectineus?

Flexion and Adduction
(dual action = dual nerve and blood supply)

19

what is the main function of the quadriceps femoris and what are its components?

Extensor of the Knee against gravity
Rectus Femoris
Vastus Lateralis
Vastus Medialis (reaches more distally)
Vastus Intermedius

20

what are the main components of the Medial and lateral Patellar Retinaculum

the insertion sit of the medial and lateral vastus around the patella

21

what is particularly important about rectus femoris?

crosses both he hip and the knee joint and as such is able to flex the hip and extend the knee

22

what are the muscles contained in the medial (adductor) compartment of the knee?

Pectineus
Adductor Longus
Adductor Brevis
Adductor Magnus
Gracilis

23

the adductor muscles originate at ---1--- and insert into ---2---

1 Inferior Pubic Rami
2 Linea Aspera

24

the adductor hiatus is formed by which muscle and is located where?

by adductor magnus and is located between the tendon fibres and the medial condyle of the femur. Through it passes the Femoral Artery

25

what are the main muscles of the posterior (flexor) compartment of the thigh? {M-L}

Hamstrings (Semimembranous, Semitendinosus, Biceps Femoris)

26

with of the muscles of the posterior comportment of the hip are ALSO involved in the extension of the hip?

Semitendinous
Semimembranosus
Long Head of Biceps

27

What does the pneumonic Say Grace Before Sex stand for?

Semitendinosus
Gracilis
Bursa
Sartorius
