Answer 3

-Originates from the greater trochanter and the lateral lip of the of the linear aspera of the femur

-Innervation: femoral nerve

Question 4

Origin and insertion of the vastus intermedius

Answer 4

-Originates from the anterior and lateral surfaces of the femoral shaft

-innervation: femoral nerve

Question 5

Answer 5

-Originates from the inter trochanteric line and medial lip of the linear aspera of the femur

-innervation: femoral nerve

Question 6

Origin and insertion of the Rectus femoris

Answer 6

-Originates from the anterior inferior iliac spine and the ilium of the pelvis
-attaches to the patella via the quadriceps femoris tendon
-Innervation: femoral nerve

Question 7

Answer 7

-Originates from the anterior superior iliac spine
-attaches to the superior, medial surface of the tibia
-innervation: femoral nerve

Question 8

Origin and insertion of the pectineus
