Lower Limb Anatomy Quiz

Hip Joint Anatomy

• The teres ligament in the hip joint strengthens the joint capsule and helps to stabilize the femoral head.

Labrum Function

• The labrum, a fibrocartilaginous ring, deepens the acetabulum, allowing for greater articulation and increasing the range of motion.

Acetabular Fossa

• The acetabular fossa is divided into a central non-articular region and a peripheral articular region.

Hip Joint Mobility

• The hip joint has 3 degrees of freedom, allowing for flexion, extension, abduction, adduction, rotation, and circumduction.

Congruency in Hip Joint

• The head of the hip joint maintains congruency with the acetabulum.

Transverse Acetabular Ligament

• The transverse acetabular ligament completes the acetabular rim, converting the acetabular notch into a foramen.

Hip Joint Structure

• The acetabular labrum is described as 'horseshoe-like' in shape.

Weight Bearing Effects

• As weight bearing occurs, the acetabulum is compressed, increasing the stability of the hip joint.
