Question

Quizplus · Accepted Answer

Gyri are the raised folds on the surface of the cerebral cortex, while sulci are the grooves or indentations between them. Together, these gyri and sulci create the characteristic wrinkled appearance of the brain. Therefore, choices A and B are both correct. Choices C and D are incorrect as lobes refer to larger divisions of the brain, and nuclei refer to clusters of neurons located deeper within the brain.
