1
Q

The Iliopsoas muscle consists of?

A

Psoas Major and Iliacus muscles

2
Q

Psoas Major Origin

A

Lumbar Vertebrae

3
Q

Iliacus origin

A

Iliac Fossa of the Pelvis

4
Q

Iliopsoas Attachment

A

Lesser Trochanter of the Femur

5
Q

Action of Iliopsoas

A

Flexes and Laterally Rotates at the Hip

6
Q

Psoas Major Innveration

A

Anterior Rami of L1/L2/L3

7
Q

Iliacus Innveration

A

Femoral Nerve (L2/L3/L4)

8
Q

Quadriceps Femoris consists of how many Muscles and what are they called?

A

4 - Rectus Femoris
Vastus Lateralis
Vastus Intermedius
Vastus Medialis

9
Q

Rectus Femoris Origin(s)

A

Ilium, just Superior to the Acetabulum and the Anterior Superior Iliac Spine (ASIS)

10
Q

Quadriceps Femoris Attachment

A

The 4 Muscles converge to form a tendon (Quadriceps Tendon) which attaches to the Patella

11
Q

How does the Patella attach to the Tibia

A

Patellar Ligament

12
Q

Quadriceps Femoris Action

A

Extension at the Knee Joint

13
Q

Additional action of Rectus Femoris

A

Flexion at the Hip Joint.

It is the only part of the Quadriceps to cross 2 joint structures.

14
Q

Innervation of the Quadriceps Femoris muscles

A

Femoral (L2/L3/L4)

15
Q

Which of the Vastus Muscles is the Deepest

A

Vastus Intermedius

16
Q

Sartorius Origin

A

Anterior Superior Iliac Spine

17
Q

Sartorius Attachment

A

Superior Medial Surface of the Tibia

18
Q

Sartorius Actions

A

At the Hip: Flexion, Abduction and Lateral Rotation

At the Knee: Flexion

19
Q

Sartorius Innervation

A

Femoral (L2/L3/L4)

20
Q

Pectineus Origin

A

Pectineal line on the Anterior Surface of the Pelvis (Superior Pubic Rami)

21
Q

Pectineus Attachment

A

Pectineal line on the Posterior side of the Femur, just Inferior to the Lesser Trochanter.

22
Q

Pectineus Action

A

Adduction and Flexion at the Hip Joint.

23
Q

Pectineus Innveration

A

Femoral (L2/L3/L4). May also have innervation from the Obturator nerve (L2/L3/L4)

24
Q

Test for Femoral Nerve Damage

A

Patient in Supine Position with the knee slightly flexed. Ask them to extend the leg and resist their movement. Quadriceps definition should be evident if normal.
