Which of the following is not a lobe of the cerebrum?

• A. Limbic
• B. Frontal
• C. Parietal
• D. Temporal

Answer: (A)

The cerebrum is divided into four major lobes by the bones outlining the skull: frontal, parietal, temporal, and occipital. Each of these lobes has distinct functions, such as planning and movement (frontal), processing touch and spatial information (parietal), processing sound and memory (temporal), and vision (occipital). The limbic system, on the other hand, is a network of structures involved in emotion, motivation, and memory. It lies along the inner surface of the cerebrum and surrounding areas, and while some texts refer to a limbic “lobe,” it is not one of the four primary cerebral lobes used in basic anatomical classification. Therefore, limbic is not a lobe of the cerebrum.
