Q

Ligamentum teres

*blood supply

A

(ligament of the head of femur)
acetabular fossa + the fovea of the femur

  • weak and hase little influence on joint stabilization of hip.
  • transmits the acetabular branch of the obturator artery into the head of femur

Q

Tibial collateral ligament (MCL)

A

medial femoral epicondyle + medial condyle of tibia

Q

Bursae

A

reduce wear and tear and therefore, prevent damage and pain by being placed between structures that would otherwise rub against eachother

Q

Posterior (dorsal) interosseous sacroiliac ligament

A

Iliac tuberosity to the posterior surface of the sacrum

Prevents forward and downward dislocation of the sacrum from the ilia.
Assists to prevent sacral nutation

Q

Sacrospinous ligament

A

Lateral Sacrum to the ischial spine

Prevents sacral nutation

17
Q

Inguinal ligament

A

ASIS to pubic tubercle

Doesn’t limit movement.
- Connects bone together

18
Q

Anterior longitundinal ligament

A

Runs along anterior surface of the vertebral column attaching to vertebra as it passes

Limits spinal extension

19
Q

Superior and Inferior interpubic ligaments

A

Pubic body + Pubic body

Helps bind the left and right hip bones together at the front across the pubic symphysis

20
Q

Sacrococcygeal Ligaments

A

Between inferior portion of sacrum and coccyx

Strengthens the joint between the sacrum and coccyx, preventing dislocation

21
Q

Transverse Acetabular ligament

A

Converts the body acetabular notch into a foramen by crossing where the acetabular labrum would be

22
Q

Supraspinous ligament of the spinal column

A

Runs along the superficial midline of the posterior vertebral column, attaching to each spinous process it passes

Limits extreme flexion of the vertebral column

23
Q

Which ligament prevents counter-nutation of the sacrum?

A

Long posterior sacroiliac ligament

24
Q

Which ligaments prevent nutation of the sacrum?

A
  1. Posterior interosseous sacroiliac ligament
  2. sacrotuberous ligament
  3. sacrospinous ligament
