1

division of abdomen into 4 regions

horizontal line and vertical line
right and left upper and lower quadrants

2

division of abdomen into 9 regions

2 horizontal and 2 vertical planes

vertical - two midclavicular
horizontal - subcostal at LV3 and transtubercular plane at LV5

3

subcostal plane?

at LV3; lowest limit of costal margin

4

transtubercular plane?

at LV5

5

different 9 regions of abdomen?

epigastric
umbilical
pubic
hypochondriac r/l
inguinal r/l
lateral regions r/l

6

transpyloric plane

LV1

7

subcostal plane

LV3

8

transumbilical plane

LV3-LV4

9

supracristal plane

LV4

10

transtubercular plane

LV5

11

interspinous plane

SV1

16

osseous structures?

lumbar vertebrae 1-5
-above abdomen ribs 7-12
-below abdomen pelvic girdle

above and below provide support

17

campers fascia

superficial fatty layer
loose CT

18

scarpas fascia

deeper membranous layer (thin)
-covers muscles of abdomen

-continuous with colles and dartos fascia of perineum
-attaches to iliac crest, fascia lata below inguinal ligament, pubic tubercle

19

fundiform ligament

specialization of scarpas fascia

20

muscles of abdomen

(superficial to deep)
external
internal
transversus abdominus muscle

21

fascia of abdomen?

2 layers superficial
3 layers deep

22

deep facia of abdomen?

beneath the muscle (superficial to deep)
-transversalis fascia
-extraperitoneal fascia (subserous fascia)
-parietal peritoneum - serous membrane of abdomen

23

external abdominal oblique attachments

origin - outer surfaces of ribs 5-12
insertion - anterior iliac crest, external abdominal aponeurosis attaches to linea alba from xiphoid process to pubic symphysis

hands in front pockets

24

external abdominal oblique action

flex vertebral column and pelvis
-compression and support of abdominal viscera

one side acting - lateral flexion of trunk and rotation to opposite side

25

innervation of external abdominal oblique

intercostal n
subcostal n
iliohypogastric n (ventral ramus L1)

26

internal abdominal oblique attachments

origin - thoracolumbar fascia, anterior iliac crest, lateral inguinal ligament
insertion - inferior border of ribs 9-12; via internal abdominal oblique aponeurosis to linea alba from xiphoid process to pubic symphysis

hands in back pockets

27

internal abdominal oblique action

flexion of vertebral column
compression and support of abdomen viscera
one side acting alone causes lateral flexion of trunk and rotation to same side

28

internal abdominal oblique innervation

intercostal n
subcostal n
iliohypogastric n
ilioinguinal n

29

transversus abdominis attachments?

origin - inner surface ribs 7-12, thoracolumbar fascia, anterior iliac crest, lateral inguinal ligament
insertion - aponeurosis of linea alba

30

transversus abdominis action?

compression and support of abdomen viscera
