The lobes of the cerebrum named for the bones that cover them are the frontal, parietal, temporal, and which other lobe?

• A. Sphenoidal
• B. Insular
• C. Ethmoidal
• D. Occipital

Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the anatomy of the cerebrum, which is the largest part of the brain and is divided into lobes. Each lobe is named after the cranial bones that cover them.
2. Step 2: Recall the names of the cranial bones that correspond to the lobes of the cerebrum: frontal bone (frontal lobe), parietal bone (parietal lobe), temporal bone (temporal lobe), and occipital bone (occipital lobe).
3. Step 3: Eliminate the incorrect options by identifying bones that do not correspond to lobes of the cerebrum. For example, the sphenoidal and ethmoidal bones are part of the skull but do not have corresponding lobes in the cerebrum.
4. Step 4: Consider the insular lobe, which is a hidden lobe of the cerebrum but is not named after a cranial bone. This further confirms that the correct answer must be a lobe named after a cranial bone.
5. Step 5: Conclude that the occipital lobe is the correct answer, as it is named after the occipital bone, which covers the posterior part of the cerebrum.
