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
Q

Rectus abdominis (action)

A

compress, support abdominal viscera

-flex trunk

26
Q

what surrounds the rectus abdominis?

A

Rectus sheath

27
Q

Where is the arcuate line and what does it denote?

A

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
Q

What supplies the superior, deep part of the abdominal wall?

A

Superior epigastric artery and vein

the artery is a terminal brand of the internal thoracic artery

29
Q

What supplies the lateral, deep part of the abdominal wall?

A

10th and 11th posterior intercostal arteries.

Subcostal arteries

30
Q

What supplies the inferior, deep part of the abdominal wall?

A

inferior epigastric artery and vein.

artery is from the external iliac artery

31
Q

What parts does the lesser omentum bind to ?

A

Connects the lesser curvature of the stomach and the proximal part of the duodenum to the liver

32
Q

What parts does the greater omentum bind to ?

A

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
Q

Where does the esophagus join the stomach?

A

at the left 7th costal cartilage and t11 vertebra

34
Q

where do the teniae coli start and end

A

starts at the base of the appendix and ends at the rectosigmoid junction

35
Q

Location of the liver

A

deep to ribs 7-11 on the right side , does not cross midline

36
Q

Lobes of the liver

A

right, left, caudate and quadrate

37
Q

Porta hepatis

A

the point of entry of the hepatic arteries and portal vein and exit for the hepatic ducts

38
Q

what splits the right and left lobe?

A

falciform ligament

39
Q

What are the two ligaments of the lesser omentum and their connections?

A
  • 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
Q

what forms the portal vein?

A

Union of the splenic and superior mesenteric vein

41
Q

location of the pancreas

A

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
