Question

which of the following cavities are contained within the dorsal body cavity? select one: a. pelvic and abdominal cavities b: ventral and anterior cavities c. cranial and vertebral cavities d. all of the above

Explanation:

To solve this, we recall the structure of body cavities. The dorsal body cavity is located along the back (posterior) of the body and is divided into two main parts: the cranial cavity (which houses the brain) and the vertebral (or spinal) cavity (which houses the spinal cord).

• Option a: Pelvic and abdominal cavities are part of the ventral (anterior) body cavity, so this is incorrect.
• Option b: Ventral and anterior cavities are the same as the ventral body cavity (which includes thoracic, abdominal, pelvic), so this is incorrect.
• Option c: Cranial and vertebral cavities are indeed within the dorsal body cavity, so this is correct.
• Option d: Since a and b are incorrect, this is also incorrect.

Answer:

c. Cranial and vertebral cavities
