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?
