The cavity located in the back of the body is called the:

• A. Cranial Cavity
• B. Dorsal Cavity
• C. Midsagittal Plane
• D. Nerve Tissue

Answer: (B)

The back of the body corresponds to the dorsal side, and the dorsal cavity runs along that back side. This cavity includes two sections: the cranial cavity inside the skull, which houses the brain, and the vertebral (spinal) cavity inside the backbone, which contains the spinal cord. So, when referring to the cavity located at the back, the dorsal cavity is the correct term. The cranial cavity is just the part inside the skull, not the whole back; the midsagittal plane is an imaginary divider through the body, not a cavity; nerve tissue is a type of tissue, not a cavity.
