18
Q

What is the pelvic inlet?

A

the plane surface that define the boundary between abdominal cavity and pelvic cavity

19
Q

A

above pelvic inlet

below pelvic inlet

21
Q

Border of Pelvis major? (ant, post, lateral)

A

Ant: abdominal wall

Post: L5-S1

Lateral: iliac fossae

21
Q

Border of pelvic major? (ant, post., infer., lateral)

A

Ant: pubis

Post: sacrum & cocyx

Infer: pelvic diaphragm

Lateral: obturator int

22
Q

Border of pelvic outlet (inferior pelvic aperture)?

A

inferior pubic remi

sacrotuberous lig

ischial tuberosity

pubic symphysis

cocyx

23
Q

What is female pelvis different from male?

A

wider pubic arch with shallower subpubic angle

wider pelvic inlet

thinner bone in iliac foassae

24
Q

What are two joints in vertebral column of pelvis?

A

L5:sacrum

sacrum:cocyx

25
Q

What type of joints in L5:sacrum vertebrae?

A

symphysis btw bodies

plane joints btw arches

26
Q

What joints are there in sacrum:cocyx?

A

only symphysis and no plane joints

27
Q

why there are no plane joints btw sacrum:cocyx?

A

because there are no s4 and s5 in sacral vertebrae

28
Q

what ligament does sacrum:cocyx have? Where is it come from?

A

sacrococcygeal lig

the continuation of anterior/posterior longitudal ligament into cocyx

28
Q

What are pelvic joints?

A

anterior joints: pubic symphysis

posterior joints: 2 sacroiliac joints

29
Q

What is the sacroiliac joint?

A

where is the os coxae articulate with sacrum

29
Q

What are the ligament in pubic symphysis?

A

superior pubic lig

arcuate pubic lig

30
Q

Where is the superior pubic lig? arcuate pubic lig?

A

superior pubic tubercle

inferior pubic arch

31
Q

What ligaments are there in sacroiliac joint?

A

ventral/ant sacroiliac lig

interosseous SI lig

Post SI lig

iliolumbar lig

sacrotuberous ligs

sacrospinous ligs

32
Q

What does ventral/ant and dorsal/post SI lig do?

A

reinforce the joints btw iliac and sacrum

33
Q

What is the strongest ligament in the body? where is it

A

interosseous SI lig

between os coxae and sacrum

34
Q

What is the iliolumbar lig?

A

connecting the transverse process of L5 to iliac fossae

35
Q

What does sacrotuberous lig do?

A

connect posterior sacrum to ischial tuberosity

36
Q

What does sacrobspinous ligs do?

A

connect anterior sacrum to ischial

37
Q

Where does sacral plexus nerve exit?

A

greater sciatic foramen

38
Q

Where does pudendal nerve and obturator internus enter?

A

less sciatic foramen

39
Q

What exit through greater sciatic foramen?

A

sacral plexus nerve

40
Q

What reenter lesser sciatic foramen?

A

pudendal nerve and obturator internus
