upshaped acetabulum (more contact area for a better connection)
muscles around the joint (prevent hyperextension)
ligaments (iliofemoral, pubofemoral, ischiofemoral)
the fibrous capsule(during extreme movement twists and pulls together to limit movement)
the acetabular labrum(increases articular contact area fro better connection)
the ligament teres (accessory ligament in the head of the femur)

what are the ligaments found in the hip joint

Answer 2

iliofemoral, ischiofemorale and pubofemoral. all hold ball to socket.

Question 3

Answer 4

is posterior and prevents over rotation. found on the anterior
