Flashcards in Lower Limbs - Muscles and Movements Deck (29):
1

Number of muscle compartments in the thigh

Four

2

Muscles in anterior thigh compartment

Quadriceps

3

Muscles in lateral thigh compartment

Gluteal

4

Muscles in posterior thigh compartment

Hamstrings

5

Muscles in medial thigh compartment

Adductors

6

Role of interosseus membrane in leg

Links tibia and fibula
Surface for muscle attachments

7

Do different thigh muscle compartments have their own nerve supply?

Yes

8

Quadriceps muscles

1) Rectus femoris
2, 3, 4) Vastus

9

Muscle maintaining proper alignment of patella

Vastus medialis

10

Effect on patella of too-weak vastus medialis

Patella can dislocate laterally

11

Muscles of hamstring
1)
2)
3)

1) Semimembranous
2) Semitendenous
3) Biceps femoris

12

Two-joint muscles of hamstrings

Semimembranous, semitendenous, biceps femoris (long head)

13

Adductor muscles most commonly injured

Adductor longus (groin injury)

14

Gluteal muscles
1)
2)
3)

1) Gluteus maximus
2) Gluteus medius
3) Gluteus minimus

15

Superficial gluteal muscle

Gluteus maximus

16

Deep gluteal muscles

Gluteus medius, gluteus minimus

17

Role of gluteus medius and gluteus minimus

Adduct hip from below, maintain position of pelvis during locomotion

18

Anterior muscles of leg
1)
2)
3)

1) Tibialis anterior
2) Extensor hallucis longus
3) Extensor digitorum longus

19

Tenoperiostosis

Shin spints

20

Technical term for shin splints

Tenoperiostosis

21

Cause of tenoperiostosis

Overuse of tibialis anterior, extensor hallucis longus, extensor digitorum longus

22

Lateral muscles of leg

Peroneal muscles

23

A role of peroneal muscles

Proprioception in ankle strain

24

Posterior superficial muscles of leg:
1)
2)
3)

1) Gastrocnemius
2) Plantaris
3) Soleus

25

Posterior deep muscles of leg:
1)
2)
3)

1) Tibialis posterior
2) Flexor hallucis longus
3) Flexor digitorum longus

26

Role of soleus

Keep upright position, as centre of gravity passes behind hips.
Therefore soleus is always tensed when standing

27

Compartment syndrome

Muscles are wrapped in tight fascia.
If there is swelling in compartment, structures are at danger of compression EG: neurovascular bundle

28

Treatment for compartment syndrome

Fasciotomy

29

Muscles forming Achilles tendon

Gastrocnemius
Soleus
