Large, triangular

48
Q

Where is the ischial spine found?

A

At the inferior margin of the greater sciatic notch

49
Q

What does the ischial spine provide?

A

A ligamentous attachment

50
Q

What does the ligamenteous attachment separate?

A

The greater sciatic notch from the lesser sciatic notch

51
Q

How does the lesser sciatic notch differ from the greater?

A

It is more inferior, rounded, smaller, and smooth-surfaced

52
Q

What does the lesser sciatic notch serve as?

A

A trochlea or pulley for a muscle that emerges from the bony pelvis

53
Q

What is the ischial tuberosity?

A

A rough bony projection

54
Q

Where is the ischial tuberosity found?

A

At the junction of the inferior end of the body of the ischium and its ramus

55
Q

What is the purpose of the ischial tuberosity?

A

Bodys weight rests on this when sitting

Provides proximal, tendinous attachment of posterior thigh muscles

56
Q

What does the pubis form?

A

The anteromedial part of the hip bone

57
Q

What does the pubis contribute to?

A

The anterior part of the acetabulum

58
Q

What does the pubis provide?

A

Proximal attachment for the muscles of the medial thigh

59
Q

What is the pubis divided into?

A

A flattened, medially placed body, and the superior and inferior rami

60
Q

How do the superior and inferior rami project?

A

Laterally from the body

61
Q

What does the symphysial surface of the body of the pubis articulate with medially?

A

The corresponding surface of the body of the contralateral pubis

Q

What closes the obturator foramen?

A

The thin, strong obturator membrane

77
Q

What is the advantage of the presence of the foramen?

A

It minimises bony mass while its closure by the obturator membrane still provides extensive surface area on both sides for fleshy muscle attachment

78

The joint

81
Q

What is the acetabular notch?

A

Where the margin of the acetabulum is incomplete inferiorly

82
Q

What is the acetabular fossa?

A

The rough depression in the floor of the acetabulum extending superiorly from the acetabular notch

What do the acetabular notch and fossa create?

A

A deficit in the smooth lunate surface of the acetabulum

84
Q

What is the lunate surface of the acetabulum?

A

The articular surface receiving the head of the femur

85
Q

How is the isolated hip bone or bony pelvis placed in the anatomical position?

Inferiomedial to the acetabulum

88
Q

How does the internal aspect of the body of the pubis face in the anatomical position?

A

Almost directly superiorly
