Coxal Bone

Name and Classify the Joints of the Pelvic Girdle

Answer 3

Joints:

1. Hip Joint
   - Synovial Ball and Socket Diathrotic Multiaxial
2. Pubic Symphasis Joint
   - Cartilaginous Symphasis Ampiathrotic
3. Sacroilliac Joint
   - Synovial Plane Diathrotic Non axial

Question 4

Ligaments of the Hip

Name, Shape, Location and Purpose of the Ligaments at the Hip Joint

Most important contributing factor to the stability of the Joint

Answer 4

1. Illio-femoral
   - V Shape
   - Anterior
   - Increased Stability
2. Ishio-femoral
   - Spiral Shape
   - Posterior
   - Screws Femur into Acetabulum
3. Pubo-femoral

• Triangular Shape
• Inferior

Factor: Shape of articulating surfaces

Question 5

Ligaments of the Pelvis

Name, Identify position and Role of these three ligaments

Answer 5

1. Illio-lumbar Ligament
   - Illiac Spine to Lumbar Vertebrae
   - Holds coxal bones together
2. Sacro-spinous Ligament
   - Sacrum to Ishial Spine
   - Prevents posterior tilt of sacrum (winging action)
3. Sacro-tuberous Ligament
   - Sacrum to Ishial Tuberosity
   - Prevents posterior tilt of sacrum (winging action)
