Which of the Following Factors Is FALSE Regarding the Stability

question 39

Multiple Choice

Which of the following factors is FALSE regarding the stability of the "hip" joint?

• A) The articular capsule is very dense and strong tissue that extends from the rim of the acetabulum to the neck of the femur.
• B) The acetabular labrum is a rim of fibrocartilage that increases the depth of the socket, thus making dislocation rare.
• C) Several strong reinforcing ligaments include the iliofemoral and ischiofemoral ligaments, which are made of dense regular connective tissue and provide support to the joint.
• D) The hip joint is formed by the extremely stable articulation of the femur to the coxal bone via a cartilaginous joint consisting of hyaline cartilage.
• E) Several large muscles cross the joint and contribute to its stability.
