The statement a. The central sulcus marks the boundary between the frontal and parietal lobes is true .
a. The central sulcus marks the boundary between the frontal and parietal lobes.
This statement is true. The central sulcus is a prominent anatomical feature on the cerebral cortex, and it serves as a landmark that separates the frontal lobe, responsible for motor functions and higher cognitive processes, from the parietal lobe, which is involved in sensory processing.
b. It is a gray matter structure that functions in emotions and memory.
This statement is not accurate. The central sulcus is not a gray matter structure; it is a groove or furrow on the surface of the cerebral cortex.
Gray matter is found throughout the cortex but is not specifically associated with the central sulcus.
c. It is a large white matter structure that connects the right and left cerebral hemispheres.
This statement is not true. The structure that connects the right and left cerebral hemispheres is the corpus callosum, not the central sulcus.
The central sulcus is a fold on the surface of the cortex and is not primarily involved in interhemispheric connectivity.
d. It is a gray matter structure that particularly provides for the formation of long-term memories.
This statement is not accurate. Long-term memory formation is associated with structures like the hippocampus and other regions of the limbic system, but it is not specifically linked to the central sulcus.
The central sulcus is primarily a boundary marker between different functional areas of the cerebral cortex.
