Which of the following structures contains cerebrospinal fluid?
A

B
Cerebral cortex
C
Ventricles of the brain
D
Cerebellar peduncles
Verified step by step guidance1
Understand the role of cerebrospinal fluid (CSF): CSF is a clear fluid that surrounds the brain and spinal cord, providing cushioning, nutrient delivery, and waste removal. It is primarily found in specific structures within the central nervous system.
Identify the structures associated with CSF: CSF is contained within the ventricles of the brain, the central canal of the spinal cord, and the subarachnoid space surrounding the brain and spinal cord.
Clarify the function of ventricles: The ventricles are interconnected cavities within the brain where CSF is produced by the choroid plexus. These include the lateral ventricles, third ventricle, and fourth ventricle.
Compare the listed structures: The basal ganglia and cerebral cortex are regions of the brain involved in motor control and higher cognitive functions, respectively, but they do not contain CSF. Similarly, the cerebellar peduncles are bundles of nerve fibers connecting the cerebellum to other parts of the brain, and they do not house CSF.
Conclude that the ventricles of the brain are the correct answer, as they are the primary structures containing cerebrospinal fluid.
