Q

what is the only distinguishable layer of fascia of the flat muscles and describe it?

A

Transversalis fascia
It is the layer deep to the transversalis abdominis muscle
continuous with the fascia of the internal aspect of the abdominal wall, the endoabdominal fascia

21
Q

what is deep to the tranversalis fascia and function?

A

Extraperitoneal fascia

stores varying amounts of fat.

22
Q

What is deep to the extraperitoneal fascia and describe it?

A

Peritoneum

a thin serous membrane lining the abdominal walls and some viscera in the abdominal cavity.

23
Q

Rectus abdominal(Attachments)

A
  • pubic symphysis and pubic crest

- xiphoid process and costal cartilages 5-7

24
Q

Rectus abdominal(innervation)

A

segmental thoracoabdomial nerves

25
Rectus abdominis (action)
compress, support abdominal viscera | -flex trunk
26
what surrounds the rectus abdominis?
Rectus sheath
27
Where is the arcuate line and what does it denote?
It is at the lower 1/4 of the rectus abdominus | Below the arcuate line the posterior surface of the rectus muscle is not covered in rectus sheath
28
What supplies the superior, deep part of the abdominal wall?
Superior epigastric artery and vein | the artery is a terminal brand of the internal thoracic artery
29
What supplies the lateral, deep part of the abdominal wall?
10th and 11th posterior intercostal arteries. | Subcostal arteries
30
What supplies the inferior, deep part of the abdominal wall?
inferior epigastric artery and vein. | artery is from the external iliac artery
31
What parts does the lesser omentum bind to ?
Connects the lesser curvature of the stomach and the proximal part of the duodenum to the liver
32
What parts does the greater omentum bind to ?
it connects the greater curvature and the proximal part of the duodenum then descends and folds back and attaches to the anterior surface of the transverse colon and its mesentery
33
Where does the esophagus join the stomach?
at the left 7th costal cartilage and t11 vertebra
34
where do the teniae coli start and end
starts at the base of the appendix and ends at the rectosigmoid junction
35
Location of the liver
deep to ribs 7-11 on the right side , does not cross midline
36
Lobes of the liver
right, left, caudate and quadrate
37
Porta hepatis
the point of entry of the hepatic arteries and portal vein and exit for the hepatic ducts
38
what splits the right and left lobe?
falciform ligament
39
What are the two ligaments of the lesser omentum and their connections?
- Hepatoduodenal ligament which is between the porta hepatis and the duodenum and encloses the portal triad lymphatic vessels and hepatic plexus of the nerves - hepatogastric ligament between the groove of the ligamentum venosum of the liver and the lesser curvature of the stomach
40
what forms the portal vein?
Union of the splenic and superior mesenteric vein
41
location of the pancreas
the neck of the pancreas overlies the 1st and 2nd lumbar vertebrae. its body is t the left and head to the right with the head being inferior to the tail
42
Location of the kidney
The superior part of the kidney lie deep to the 11th and 12th rib
43
location of the spleen
deep to the left rib 9-11
44
The three types of branches off of the abdominal aorta.
Anterior visceral which are unpaired lateral visceral which are paired posterior parietal which are paired
45
branches of the superior mesenteric artery
Inetrior pacreaticduodenal arety, jujunal and ileal artery, middle colic artery, right colic artery, ileocolic artery
46
Branched of the inferior mesenteric artery
Left colic artery, sigmoid arteries, and superior rectal artery
47
list lateral visceral arteries
- inferior phrenic - suprarenal - renal - reproductive
48
where does the IVC start and from what does it originate?
Starts at T5 inferior ro the bifurcation of the aorta with the union of the common iliac veins
49
Retroperitoneal organs | SAD PUCKER
``` S: suprarenal (adrenal) gland A: aorta/IVC D: duodenum (second and third part) P: pancreas (except tail) U: ureters C: colon (ascending and descending) K: kidneys E: (o)esophagus R: rectum ```
