Flashcards in Muscles Of Anterior Thigh Deck (14):
1

Psoas minor

Origin: T12-L1
Insertion: iliopectineal arch
Movement: flexion, lateral flexion of lumbar sacral, assist upwards rotation of pelvis
Nerve: branches of the ventral rami of L1 (lumbar plexus)
Artery: lumbar arteries

2

iliacus

origin: iliac fossa
insertion: lesser trochanter of femur
action: flexion + external rotation of hip
nerve: femoral nerve (L2-L4)
Artery: medial circumflex femoral artery

3

sartorius

Origin: anterior superior iliac spine
Insertion: near tibial tuberosity on medial side of tibia
action: flexion, ABduction, external rotation, flexion of knee joint, internal rotation of knee
Nerve: femoral nerve L2,L3
Artery: lateral circumflex femoral artery

4

rectus femoris (superficial)

origin: anterior inferior iliac spine
insertion: patella + tibial tuberosity
action: flexion of hip joint (contract) + extension of knee joint (extend)
nerve: femoral nerve (L2-L4)
Artery: lateral circumflex femoral artery

5

vastus lateralis

origin: greater trochanter of femur (tibial tuberosity)
insertion: tibial tuberosity + patella
action: extension of knee
nerve: femoral nerve (L2-L4)
artery: transverse circumflex femoral artery, lateral circumflex femoral artery

6

Vastus intermedius

origin: proximal anterior lateral surface of femur
insertion: tibial tuberosity via the patella
action: extension of knee
Nerve: femoral nerve
artery: lateral circumflex femoral artery, descending branch of lateral circumflex artery

7

Vastus medialis

origin: intertrochanteric line
insertion: patella and tibial tuberosity
action: extension of knee
nerve: femoral nerve (L2-L4)
artery: lateral circumflex femoral artery, perforating arteries of deep femoral artery

8

patella ligament

Origin: apex of patella
Insertion: tibial tuberosity

9

Psoas major

Origin: anterior lower transverse process of T12 - L5
Insertion: less trochanter of femur
Action: flexion + external rotation, bends lumbar vertebrae column
Nerve: ventral rami of L1-L3
Artery: lumbar arteries

10

Which nerve is muscles in the anterior compartment of the thigh innervate by? nerve roots?

femoral nerve (L2-L4)

11

Function of anterior thigh muscles?

extend leg @ knee joint

12

Name the main muscles in the anterior thigh

pectineus
sartorius
quadriceps femoris
end of iliopsoas muscles (pass through anterior compartment)

13

When do you test for the quadriceps femoris?

in suspected femoral nerve damage (anterior thigh)

14

How do you test for quadriceps femoris?

ask patient to lie in supine position (facing ceiling - not prone)
knee slightly flexed
ask patient to extend leg against resistance (e.g. you push against)
the contraction of quadriceps femoris should be visible
