2 attachment sites of Internal Abdominal Obliques and Transversus abdominus
|
Anteriorly - on linea alba
Posteriorly on the Lumbar fascia |
|
|
Attachment sites of External abdominal obliques
|
Lower 8 ribs - w/ Serratus Anterior and Latissimus Dorsi (Upper and Lower 4 ribs, respectively)
and Xiphoid/linea alba - FREE EDGE posterior |
|
|
Descibe the lower edge attachment of the external oblique: ligament and 3 attachment sites
|
The inguinal ligament is formed w/ the ASIS, Pubic Tubercule and Pubic crest
|
|
|
What is the:
Above attachment of Internal obliques Anterior Posterior Inferior |
Above: Lower ribs
Post: lumbar fascia Anteroir: linea alba Inferior: Lateral half of inguinal ligament annd Pubic tubercule |
|

Inferior: (2) Superior: (2) Lateral: Midd Sup/Inf: |
Inferior: Pubic symph/crest
Superior: Ribs 5-7/Xyphoid Lateral: Semilunar line In center: Tendinous insertions (6pack lines) |
|
|
how are the lower rectus abdominus muscles vascularly supplied?
|
Inferior epigastric vessels which pass superficially (anterioirly) to the Arcuate line, which come from superior epigastric vessels, from internal thoracic vessels
|
|
|
Where do the lowest fibers of the ex. abdom oblique muscle attach? (2 spots) what are these 2 spots attached by?
|
THe ASIS and the Pubic Tubercule, connected by Inguinal ligament
|
|
|
What allows for passage of testes from abdomine to scrotal sac?
|
Inguinal Canal
|
|
|
How does a hernia come about?
|
Abdominal conents go thru the inguinal canal
|
|
|
What forms the CONJOINT TENDON? Where is this tendon?
|
The lower fibers of the transversus abdominus and the Internal oblique muscle, it is deep to the spermatic cord
|
|
|
Where is the rectus sheath located?
|
The anterior wall of the rectus sheath is superficial to the rectusabdominus, the posterior wall of the rectus sheath is dep to it.
|
|
|
What forms the Anterior wall of hte rectus sheath?
|
Upper 3/4: fusion of EO aponeuroisis, and anterior lamina of aponeurosis of internal oblique
lower 1/4 = aponeuroses off ALL 3 muscles |
|
|
What forms the posterior wall of the rectus sheath?
|
Upper 3/4 = posteroir lamina of internal oblique aponeurosis/transverse abdominus
Lower 1/4 - NO APONEUROSES - right on transversalis fascia |
|
|
Which nerves are found in the transverse abdominus? How can one determine the positon?
|
T7 to T11 called THORACO ABDOMINAL NERVES and T12 - subcostal nerve
T10 is @ level of umbliicus |
|
|
What is MESENTERY?
|
Double sheet of peitoneum attached to body wall
|
|
|
When an organ is completely covered in visceral peritoneum has a double attachment to the body wall called what?
|
Mesentery
|
|
|
What is the GREATER omentum?
|
The visceral peritoneum that extends from the stomach to other organs and abdominal wall
|
|
|
What is the Lesser omentum?
|
Visceral peritoneum extending from the liver
|
|
|
Which ligament connects the liver to the anterior abdominal wall?
|
FALCIFORM LIGAMENT
|
|
|
Where is the LIGAMENTUM TERES located? what is it?
|
Free margin of falciform ligament, remains of the umbilicalvein
|
|
|
a - Ext Oblique
b - linea alba c - transversus muscle/aponeurosis d - Internal oblique e - ext. oblique f - transversus muscle g - transversalis fascia h - ext oblique i - int oblique j - transverss msucle k - rectus abdominus l - rectus sheath |
|
|
What are the differences between indirect an direct hernia in terms of manifestation? (NOT direction) Which is congenital?
|
Indirect - along route of testies, thru the deep ring of the inguinal canal - CONGENITAL
Direct - thru weakness of posterior wall lat to conjoint tendon, due to transversalis fascia weaken |
|
|
What forms Hasselbach's Triangle?
|
Rectus sheath, Inf epigastric vessel and Inguinal ligament
|
|
|
How does each hernia relate to hasselbach's triangle?
|
Indirect - lateral to the epigastric artery (location of deep ring)
Direct - medial to artery WITHIN trianlge |
