A
- P: ilium and ASIS
- D: medial tibia (pes anserine)
- A: flex hip and knee; ABD and ER hip
- N: femoral n. (L2,L3)
6
Q
quadriceps femoris
A
- cumulative term for RF, VM, VL, and VI
- these 4 muscles have a common tendon (quadriceps tendon) that inserts on the patella
7
Q
the patella connects the quads to the tibia via the _____
A
patellar ligament
8
Q
the quads are the only muscles that ____ the knee
A
extend
9
Q
all of the quads are innervated by ____
A
femoral n. (L2-L4)
10
Q
rectus femoris
A
- P: AIIS
- D: quad tendon
- A: hip flexion (primary) and knee extension
11
Q
vastus lateralis
A
- P: femur
- D: quad tendon
- A: extend knee
12
Q
vastus lateralis obliquus (VLO)
A
oblique fibers of the VL that attach to the patella to stabilize it and minimize it from popping out of the groove
13
Q
vastus medialis
A
- P: femur
- D: quad tendon
- A: extend knee
14
Q
vastus medialis obliquus (VMO)
A
oblique fibers of the VM that attach to the patella to stabilize it and minimize it from popping out of the groove
15
