Hydrocephaly is a condition whereby cerebrospinal fluid accumulates around the brain. what supportive cells continue csf production despite it backing up in the subarachnoid space? question 13 options: a. microglial cells b. macrophages c. oligodendrocytes d. ependymal cells e. astrocytes

The correct answer is option d, that is, ependymal cells.

Hydrocephalus refers to the accumulation of fluid in the ventricles (cavities) deep inside the brain. The excess fluid upsurges the size of the ventricles and applies pressure on the brain. Despite the backing up of the fluid in the subarachnoid space, the production of CSF takes place spontaneously due to the assistance of supportive cells known as ependymal cells.

An example of ciliated cells, which lines the ventricles of the brain are ependymal cells, these motile cells move in a rhythmic flow and thus help in the transportation of fluid. The beating of these cilia produces appropriate movement of CSF.
