Final answer:
Ependymal cells are the neuroglial cells responsible for producing and circulating cerebrospinal fluid in the CNS.
Step-by-step explanation:
The type of neuroglial cell that participates in the production and circulation of cerebrospinal fluid is D) Ependymal cells. Ependymal cells are responsible for filtering blood to produce cerebrospinal fluid (CSF), a crucial fluid that circulates through the central nervous system (CNS). These cells line the ventricles of the brain and the central cavity of the spinal cord, comprising part of the blood-brain barrier and playing a pivotal role in maintaining a stable environment for the brain and spinal cord.
