Question

Quizplus · Accepted Answer

Ependymal cells are responsible for producing cerebrospinal fluid (CSF) that cushions the brain and spinal cord. Without these cells, the new ape species described by Dr. Nikoto would not have any CSF, which would make it difficult to protect their central nervous system from mechanical shocks and lubricate their brain tissue. However, there is no indication that their neurons are damaged, they have multiple sclerosis, or their blood-brain barrier is compromised.
