True

21
Q

What surface of the liver is located in the inferior direction?

A

Visceral surface

22
Q

Describe the location and anatomical features of the subphrenic recess.

A
  • separates the diaphragmatic surface of the liver from the diaphragm (located more anteiorly)
  • divided into L and R areas by falciform ligament
23
Q

A portion of what embryologic structure gives rise to the falciform ligament?

A
  • ventral mesentary
24
Q

A

False, its located on the right side between the right kideny and left suprarenal gland

25
Q

What is the porta hepatis of the liver?

A
  • serves as the point of entry into the liver for:
    1. hepatic arteries
    2. portal vein
  • point of exit for:
    1. hepatic ducts
26
Q

What attaches the liver to the anterior abdominal wall?

A

falciform ligament

27
Q

What is the only part of the liver not surrounded by visceral peritoneum?

A

bare area (part that is pressed against the diaphragm)

28
Q

What are the boundaries of the bare area?

A

False, they arise from the right lobe

32
Q

What are the boundaries of the quadrate lobe?

A

Left: ligamentum teres
Right: Fossa for gallbladder

-Note: the quadrate lobe is FUNCTIONALLY more related to the left lobe of the liver

33
Q

A

False, the quadrate lobe is visible on the anterior part of the liver

34
Q

What are the boundaries of the caudate lobe of the liver?

A

Left: fissure for ligamentum venosum
Right: Groove for the inferior Vena Cava

35
Q
