Chapter 12, Problem 6
The central sulcus separates the:
a. Parietal and temporal lobes
b. Parietal and occipital lobes
c. Frontal and temporal lobes
d. Frontal and parietal lobes
Verified step by step guidance1
Understand the anatomy of the brain: The brain is divided into four main lobes—frontal, parietal, temporal, and occipital. Each lobe has specific functions and is separated by sulci (grooves) or fissures.
Identify the central sulcus: The central sulcus is a prominent groove in the brain that separates two specific lobes. It is also known as the Rolandic sulcus.
Determine the lobes adjacent to the central sulcus: The central sulcus separates the frontal lobe, which is located at the front of the brain, from the parietal lobe, which is located behind the frontal lobe.
Eliminate incorrect options: Review the options provided and eliminate those that do not involve the frontal and parietal lobes. For example, the parietal and temporal lobes are separated by the lateral sulcus, not the central sulcus.
Select the correct answer: Based on the anatomical relationship, the central sulcus separates the frontal and parietal lobes.
Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Central Sulcus
The central sulcus is a prominent groove in the brain that separates the frontal lobe from the parietal lobe. It plays a crucial role in demarcating areas responsible for motor and sensory functions, making it a key landmark in neuroanatomy.

Central Dogma
Frontal Lobe
The frontal lobe is located at the front of the brain and is associated with higher cognitive functions such as reasoning, planning, problem-solving, and motor control. It is essential for voluntary movement and the regulation of emotions and behavior.

Parietal Lobe
The parietal lobe is situated behind the frontal lobe and is primarily responsible for processing sensory information from the body, including touch, temperature, and pain. It also plays a role in spatial awareness and navigation.
