Question

What are the 2 structures of the skull located above the ethmoid bone?

A) Frontal bone and occipital bone
B) Parietal bones and temporal bones
C) Zygomatic bones and maxillary bones
D) Nasal bones and lacrimal bones

Answer 1

The structures of the skull located above the ethmoid bone are the frontal bone and the parietal bones. These form part of the cranial cavity, covering and protecting the brain.

Step-by-step explanation:

The two structures of the skull located above the ethmoid bone are A) the frontal bone and the parietal bones. The frontal bone is the bone that forms the forehead and part of the top of the skull, extending back to fuse with the parietal bones. The two parietal bones are large, curved bones that form much of the top and side walls of the cranium. Together, these structures cover and protect the brain and form part of the cranial cavity. The occipital bone, in contrast, is located at the back and lower part of the cranium, so it is not a structure directly above the ethmoid bone.
