Choose the incorrect statement regarding CSF
CSF within the spinal cord can flow to the lumbar cistern at the end of the cord around the cauda equina
CSF flows from the lateral ventricles via the cerebral aqueduct into the third ventricle
CSF removes by-products of metabolism
CSF serves to provide a fluid cushion to protect the brain from injury.
CSF flows from the lateral ventricles via the foramina of Monro into the third ventricle, and then into the fourth ventricle
CSF (Cerebrospinal Fluid) is a clear fluid that surrounds the brain and spinal cord, providing several important functions. It acts as a protective cushion for the brain, helps maintain a stable environment for neural tissue, and assists in the removal of waste products from the central nervous system (CNS).
However, CSF itself does not directly remove by-products of metabolism. The primary role of CSF is to provide mechanical and biochemical protection to the CNS. The removal of waste products of metabolism, such as metabolic by-products and toxins, is primarily carried out by other systems in the body, such as the lymphatic system and the blood-brain barrier.
Therefore, the correct answer is Option 3.
