Origin of Sartorius M
ASIS
Insertion of Sartorius M.
Pes Anserinus

Insertion of Quadriceps Femoris
Tibial tuberosity
Actions of Quadriceps Femoris
Vasti - extend leg
Rectus - extends leg and flexes thigh
Innervation of quadriceps
Femoral nerve
What is chondromalacia patella?
Lateral stretch of IT band
a condition where the cartilage under the patella begins to deteriorate
What is the patellar reflex test? What is the name for the absence of this reflex?
Patellar tendon reflex tests the function of the femoral nerve and spinal cord segments L2-L4. The absence of this reflex is known as Westphal’s sign
What is the Calcaneal Tendon reflex?
This tendon reflex tests the S1 and S2 nerve roots (sciatic nerve)
What does the iliopectineal bursa do?
It is a large synovial bursa that separates the external surface of the hip joint capsule from the tendon of the iliopsoas muscle
What is osgood-schaltter disease?
A pull of the quadriceps on the tendon from the kneecap away from the shinbone (Tibial tuberosity)
Which muscle does the patellar reflex work on?
Quadriceps femoris
What is the origin of the Pectineus M?
Pecten line of pubis
What is the insertion of Pectineus?
Pectineal line (inferior to lesser trochanter)
What is the innervation of pectineus m?
Femoral nerve (occasionally a branch of the obturator n.)
What is the action of pectineus m.?
Adduct and flex thigh (at hip)
What is the origin of the adductor longus m?
Body of pubis (inferior to pubic crest)
