16
Q

When the Iliac crest ends on the Anterior side what does it form?

A

The Anterior-Superior Iliac spine.

ASIS

17
Q

What are the Main differences in male Pelvis bones to Females?

A

The Males bones generally have more dense bones and more defined surface markings and the females True pelvis is larger and wider to accommodate for child birth.

18
Q

What are the Surface markings of the Ilium portion of the Pelvis?

A

Iliac Crest, Tubercle of the iliac crest, Ala (Superior to the body), ASIS and AIIS, Body, Acetabulum, PSIS, PIIS, Greater Sciatic Notch.
Iliac Fossa, Arcuate line.

19
Q

What are all the surface markings of the Ishium portion of the Pelvis?

A

Body, Ischial Spine, Lesser Sciatic notch, Ischial Tuberosity, Ramus of the Ischium, Obturator Foreman.

20
Q

What are all the surface markings of the Pubic portion of the Pelvis?

A

Superior Ramus of the pubis, Pubic Tubercle, inferior Ramus of the Pubis, Pectineal line, body pubic crest, pubic symphysis.

21
Q

Why is there a true and false pelvis?

A

This is because the inferior portion of the Pelvis contains the Pelvic cavity and the Superior portion contains the Abdominal Cavity.

22
Q

What are the Gluteal lines and where are they located?

A

The Posterior, Inferior ad Anterior lines are used for Gluteal muscle attachment on the outer lateral surface of the wing.

23
Q

What is Pelvimetry?

A

This is the measurement of the Inlet and Outlet of the birth canal.

24
Q

What are the 2 main parts the Ilium is divided into?

A

The superior Ala and the Inferior Body.

25
Q

What is the 2 main parts the Ilium is divided into?

A

The superior Ala and the Inferior Body.

26
Q

What makes up the Acetabulum?

A

All 3 portions of the Pelvic bone.

The Ilium, Ischium and Pubic region.

27
Q

What muscle attaches to the Iliac Fossa?

A

Iliacus muscle a hip flexor.

28
Q

What is found Inferior to the PSIS?

A

The PIIS.

29
Q

What is found inferior to the PIIS?

A

The Greater Sciatic Notch which is the bottom of the Ilium portion of the bone.

30
Q

Where does the Sciatic nerve pass to the appendicular portion in the body?

A

Through the Greater Sciatic notch and the Lesser sciatic notch

31
Q

What are the 2 main portions of the Ischium split into?

A

The Superior body and the Inferior Ramus.

32
Q

Where is the Iliac tuberosity and the Articular surface of the Ilium located and what are they used for?

A

They are in the Medial portion of the Pelvic bone posterior to the Iliac Fossa and articulate with the sacrum to form the Sacroiliac Joint.

33
Q

What is the Surface marking that moves from the Articular surface of the SI joint towards the Pubic bone?

A

This is a surface marking called the Arcuate line.

34
Q

What are the 3 main parts that the Pubic bone i split into?

A

The Superior Ramus and an Inferior Ramus and an Intermediate Body between them.

35
Q

where is the Spine of the ischium located?

A

The spine is located inferior to the Greater sciatic notch and is the first bony prominense you’ll find below the notch.

36
Q

Where is the Body if the Ischium located?

A

Located laterally from the spine of the Ischium right before approaching the Acetabulum.

37
Q

Where is the Lesser sciatic notch located?

A

The lesser sciatic notch is found immediately inferior to the Spine of the Ischium.

38
Q

Where is the Obturator Foreman located?

A

Immediately inferior to the Acetabulum in between the Ischium and pubis.
