The Spinal Cavity and Cranial Cavity are the Two Parts

Question

The spinal cavity and cranial cavity are the two parts of the:
A) dorsal cavity.
B) ventral cavity.
C) abdominopelvic cavity.
D) skeletal system.

Accepted Answer

The dorsal cavity includes the cranial cavity (which houses the brain) and the spinal cavity (which runs through the vertebrae and contains the spinal cord), while the ventral cavity includes the thoracic cavity (which contains the heart and lungs) and the abdominopelvic cavity (which contains the organs of digestion and reproduction). The skeletal system is not a body cavity.
