Q

obturator foramen

A

Beneath the acetabulum is a large foramen formed by the ischium and the pubic bone

30
Q

occipitoaxial ligament

A

also known as the membrana tectoria attach the occipital bone of the skull to the dens (odontoid process) of the second cervical vertebrae C2

31
Q

odontoid process

A

it is the joint between the atlas C1 attatched to the skull and the axis C2 where rotation of the head occurs

32
Q

pars interarticularis

A

also called the isthmus is the bony area between the superior and inferior articulating facets

33
Q

pedicle

A

form the lateral sides of the vertebral foramen

34
Q

posterior sacroiliac ligament

A

The posterior sacroiliac ligament (figure 8.37) has three sections: the short sacroiliac, the long sacroiliac, and the interosseous

35
Q

pubic symphysis

A

The ligaments of the pubic symphysis are the anterior pubic, the inferior (arcuate) pubic, the posterior pubic, and the superior pubic. The function of each of these ligaments is to articulate the anterior, posterior, superior, and inferior aspects of the two pubic bones to form the pubic symphysis. Additionally, there is an interpubic fibrocartilage disc between the pubic bones

36
Q

pubic tubercle

A

Just lateral to the pubic symphysis, each pubic bone has a bony prominence on its superior surface

37
Q

sacrospinous ligament

A

The sacrospinous ligament runs from the sacrum and coccyx to the spine of the ischium.

38
Q

sacrotuberous ligament

A

acrotuberous ligament runs between the posterior inferior spine of the ilium, the sacrum and coccyx, and the ischial tuberosity.

39
Q

sacrum

A

a triagular shaped bone that contains the fused five sacral vertebrae and articulate with the bones of the pelvis

40
Q

scoliosis

A

excessive lateral curvature of the spinal column usually in the thoracic spine but sometimes to a lesser extent in the cervical and lumbar spine

41
Q

short sacroiliac ligament

A

The short sacroiliac ligament runs between the posterior ilium and the lower portions of the sacrum.

42
Q

spinous process

A

serving as another source for ligamentous and muscular attachemensts

43
Q

supraspinous ligament

A

Running between the dorsal tips of each vertebra?s spinous process, from the coccyx to the external occipital protuberance of the occipital bone

44
Q

thoracic vertebra

A

12 in number have longer and more verticle spinous processes a fovea that provide articulation for 12 pairs of ribs.

45
Q

transverse process

A

Laterally serving as sources for ligamentous and muscular attachments

46
Q
