16
Q

What is the abdominopelvic cavity

A

Inferior to the thoracic cavity, it houses organs such as the intestines, reproductive organs, liver, etc.

17
Q

What organs are found in the abdomen?

A

Stomach, intestines, spleen, liver, etc.

18
Q

What organs are found in the pelvic region?

A

Urinary bladder & reproductive organs.

19
Q

What is a serous membrane/serosa?

A

It is a thin double layer membrane that covers the surface of organs and the walls of the ventral body cavity

20
Q

How many sections are there to the Serosa?

A

Three sections

21
Q

What are the names of the sections of the serous membrane?

A

Parietal serosa, visceral serosa, & cavity

22
Q

What is the purpose of the parietal serosa?

A

It’s the part of the membrane lining the cavity walls; basically the outside layer of protection

23
Q

What is the purpose of the visceral serosa?

A

It’s the inner layer of protection protecting the organs in the double layer membrane & it comes from the parietal serosa folding in on itself.

24
Q

What is serous fluid?

A

Thin lubricating fluid that is found in the cavity and secreted by both membranes

25
Q

What are the three serous membranes in the ventral body cavity?

A

Pleura, Pericardium, Peritoneum.

26
Q

What is the purpose of having regions for the adbominopelvic cavity?

A

Due to it being a large cavity with several organs it must be split into smaller areas.

27
Q

How many quadrants is the abdominopelvic cavity split into? What are the quadrants?

A

4 Quadrants; Right Upper Quadrant, Left Upper Quadrant, Right Lower Quadrant, Left Lower Quadrant

28
Q

What planes make up the quadrants of the abdominopelvic region?

A

Transverse plane and Median plane

29
Q

What are the nine regions that the quadrants are further divided into named?

A

Umbilical Region, Epigastric Region, Hypogastric Region, Right and Left Iliac, Right and Left Lumbar Regions, Right and Left Hypochondriac Regions

30
Q

What is the centermost region?

A

Umbilical Region

31
Q

Which region is superior to the Umbilical region?

A

Epigastric Region

32
Q

Which region is inferior to the Umbilical Region?

A

Hypogastric Region

33
Q

Which region(s) is lateral to the Epigastric Region?

A

Left & Right Hypochondriac Region

34
Q

Which region(s) is lateral to the Umbilical Region?

A

Left & Right Lumbar Region

35
Q

Which region(s) is lateral to the Hypogastric region?

A

Left & Right Iliac Region

36
Q

Which region(s) is lateral to the Hypogastric region?

A

Left & Right Iliac Region

37
