Question

Name the two most specific body cavities that would be sectioned if a transverse plane were passed through the umbilicus.

a) abdominal and pelvic
b) pelvic and thoracic
c) thoracic anf vertebral canal
d) abdominal and vertebral canal

Answer 1

The transverse plane passing through the umbilicus would section the abdominal and pelvic cavities, corresponding to option (a). Correct option is a.

Step-by-step explanation:

The two most specific body cavities that would be sectioned if a transverse plane were passed through the umbilicus are the abdominal cavity and the pelvic cavity.

This division corresponds to option (a) abdominal and pelvic. These cavities are part of the larger abdominopelvic cavity, which is separated from the thoracic cavity by the diaphragm.

A transverse plane, also known as a horizontal plane, cuts perpendicularly along the long axis of the body, thus separating these two cavities from each other. The vertebral canal, while part of the dorsal cavity, would not be sectioned in a transverse plane passing through the umbilicus, as it is posterior to these cavities.
