1

Ab organs protected by

Thoracic cage and pelvis

2

9 regions of abdoment

Epigastric
Umbilical
Pubic
Left/R hypochondriac
R/L lateral (lumbar)
L/R Inguinal

3

Sucostal plane

Divides top and middle row

4

Transtubercular plane

Divides middle and lower rows

5

Midclavicular pplanes divide

Right and Left from middle row

6

Anterolateral ab wall superficial fascai

Fatty superficial (Camper's)
Deep membranous (Scarpas)

7

What is Scarpas renamed

Colles in inguinal region

8

Anterolateral deep fascia

Deep investing fascia

9

External abdominal oblique fibers run

Inferiorly and medially (hands in pockets)

10

Internal abdominal oblique fibers run

Perpindicular to external oblique (superiorly and medially)

11

Internal ab oblique changes direction at ____ to _____

ASIS
Medial and inferior

12

Transversus abdominus fibers run ____ and how to do they change?

Horizontally...inferiro to ASIS, fibers run same as internal oblique

13

Inguinal ligament formed by

Inferior free border of aponeuorsis of external ab obqliue between ASIS and pubic tubercle

14

Rectus abdominis runs ____ and enclosed by _____

Vertical
Enclosedb y aponeuroses of muscle

15

Tendinous intersections

Interruptions of rect abdom by horizontal bands

16

Rectus sheath composed of what and formed by what?

Longitudinal pocket of anterior rectus sheath and posterior rectus sheath
Formed by aponeuroses of ext ab oblique, internal ab oblique, and transversus abdominus

17

Linea semilunaris

Where anterolateral ab wall muscles continuous with retus sheath

18

Actions of anterlateral ab muscles

Support and compress viscera
Flex vertebral column with bilateral contraction
Lateral flexion of column with unilat contract
Rotation of trunk when internal ab oblique and contralateral external ab oblique contract simulataneous (turns toward internal ab oblique side)

19

Innervation of anterolateral wall muscles

Intercostal nerves T7-T12 and L1

20

Ipsilateral contraction of external and internal oblique results in

Lateral trunk flexion toward side of contraction

21

Contralateral contraction of external and internal oblique results in

Twitsting of trunk toward the internal side

22

How are internal oblique and contralateral external oblique connected?

Aponeuroses - digastric muscle

23

During rotation, rectus abdominis acts as a

Fixed post

24

Peritoneum

Serous lining of ab cavity and organs

25

Types of peritoneum and description

Parietal - lines ab wall and drapes into pelvis
Visceral - covers external surface of ab viscera

26

Functions of periotoneum

Reduce friction
Resists infection by exuding fluid and cells
Stores fat

27

Layers of abdominopevlic fascia

Transversalis fascia
Diaphragmatic fascia
Quadratus lumborum fascia
Pelvic fascia
Fascia lata

28

Blood, lymph, nerves relative to fascial lining of abdominopelvic

Blood and lymph vessels lie in the lining
Nerves lie outside

29

Abdominopelvic fascia special function

Below ASIS, it is only anterior wall strucutre posterior to rectus abdominus
Dorms inguinal ring and extends ofver spermatic cord as internal spermatic fascia

30

Arcuate line

Line at ASIS
