D) axon terminals; GABA

Question

Quizplus · Accepted Answer

The four hollow cavities in the brain are called ventricles, and they are filled with cerebrospinal fluid. The surfaces of the ventricles are lined with neural stem cells, which are specialized cells that produce neurons in the developing brain. Therefore, option B is the correct choice. The other options are incorrect because they either refer to different structures in the brain (neural pathways, synaptic vesicles, axon terminals) or a neurotransmitter (GABA).
