1-4 years

10

deep membranous subcutaneous fascia

A

scarpa’s fascia

13
Q

investing fascia of thigh

A

fascia lata

- thickened laterally (IT band), thin medially

14
Q

oval shaped opening in deep fascia, allows for passage of great saphenous v

A

saphenous hiatus (fossa ovalis)

15
Q

innervation quadriceps fermoris

A

femoral nerve

16
Q

only quad to flex the thigh

A

rectus femoris

17
Q

non-quad anterior thigh muscles

A
  • iliopsoas
  • sartorius
  • articularis genu
18
Q

helps you sit cross legged

A

sartorius

19
Q

makes sure synovial membrane of the knee doesn’t get caught with flexion or extension

A

articularis genu

20
Q

forms the medial border of femoral triangle

A

adductor longus

21
Q

which neurovasculature structure is not part of the femoral sheath?

A

femoral n.

22
Q

intermuscular tunnel for femoral neurovasculature

A

adductor (subsartorial) canal

23
Q

the short head of biceps femoris is grouped with but technically not a hamstring. why not?

A

doens’t extend the thigh, different innervation, different attachment
