23
Q

____ is a passageway from the abdominal cavity to the abdominal wall

A

Inguinal Canal

24

A

Linea Alba

29
Q

The posterior layer of the rectus sheath ends at the _____

31
Q

True or False: The abdominal WALL is continuous inferiorly with the pelvic cavity; the continuous cavity is often referred to as the abdominopelvic cavity

A

False - the abdominal CAVITY is continuous inferiorly with the pelvic cavity; the continuous cavity is often referred to as the abdominopelvic cavity
