AbdominoPelvic

Question 1

list the superficial abdominal landmarks

Answer 1

1. xiphoid process along mid sternal line
2. umbilicus along mid clavicular line
3. midclavicular line along the lateral rectus abdominus
4. pubic symphysis along mid sternal
5. inguinal ligament
6. ASIS- upwards from inguinal ligament
7. iliac crest along mid axillary line

Question 2

what are the 9 abdominal regions

Answer 2

Question 3

what are the abdomoinal quadrants

Answer 3

Question 4

what are the functions of the pelvis

Answer 4

• protects the reproductive organs
• functions as the birth canal
• excretion
• upright walking
• transfer of weight from the axial skeleton

Question 5

when do the hip bones fuse

Answer 5

age 23-25

Question 6

where do the ASIS and Pubic Tubercle align in the anatomic position

Answer 6

one the Coronal Plane

• the pelvis has an anterior tilt that allows them to align and support the weight of the abdominal and oelvic organs

Question 7

what are the bones of the hip

Answer 7

ileum ischium and pubis

meet at the Triiradiate cartilage to form the acetabulum

Question 8

list the bones of the pelvis

Answer 8

Question 9

anterior ligaments of the pelvis

Answer 9

• anterior sacroiliac
• anterior longitudinal
• obturator membrane
• inguinal ligament

Question 10

post ligaments of the pelvis

Answer 10

Question 11

what forms the 2 Sciatic foramen

Answer 11

sacrospinous ligament: sacrum to ischial spine

saccrotuberous: sacrum to ischial tuberosity

Question 12

Greater/ False pelvis

boundaries and function

Answer 12

BOUNDARIES

Superio Lateral: Iliac crests & iliac fossa

inferior: bones of pelvic inlet

FUNCTIONS

1. holds small and large intestines

Question 13

lesser/ true pelvis boundaries and function

Answer 13

BOUNDARIES

Sup: pelvic brim

Inf: pelvic outlet

FUNCITON

• holds bladder and repro organs
• smaller and narrower
• more rigid
• contains the pelvic cavity

Question 14

what forms the pelvic brim that divides the greater and lesser pelvis

(bones only)

Answer 14

promontory of the sacrum,

arcuate line of the ilium,

pectineal line (pectin of pubis)

pubic crest

Question 15

what forms the pelvic outlet

Answer 15

ant: pubic symph L&R Pubic arch

anterolateral: L&R Ischiial tuberosities
posterolateral: L&R Sacrotuberous ligaments
posterior: Coccyx

Question 16

dx betw/ the male and female pelvis

**most acc bone for sex determination

Answer 16

MALE

• bones are thicker and heavier, for support of the male’s heavier physical build and stronger muscles.
• The greater sciatic notch of the male hip bone is narrower and deeper than the broader notch of females
• subpibic angle is 70 degrees

FEMALE: adapted for childbirth,

• wider than the male pelvis,
  
  • wider distance between the 2 ASIS
• The ischial tuberositiess are farther apart,
  
  • increases the size of the pelvic outlet.
• this increased pelvic width, causes subpubic angle is larger in females greater than 80 degrees.
• The female sacrum is wider, shorter, and less curved,
• the sacral promontory projects less into the pelvic cavity, thus giving the female pelvic inlet a more rounded or oval shape
• The lesser pelvic cavity of females is also wider and more shallow than the narrower, deeper,

Question 18

what does the pelvic floor consist of

Answer 18

1. pelvic diaphragm
2. perinial pouch- superficial & deep
3. perineum

Question 19

what is the pelvic diaphragm and what does it do

Answer 19

muscular partition formed by

the levatores ani anteriorly and coccygei posteriorly

Question 20

FUNCTIONS of pelvic diaphragm

(4)

Answer 20

1. seperates the pelvic floor drom the perineum
2. provides support for pelvic and abdominal contents
3. resist increased pressure in the abdomen
4. control the passage of contents out of the pelvis
