What are two primary roles of glial cells?

Question

Quizplus · Accepted Answer

Glial cells have many roles in the nervous system, but two primary roles are forming myelin (which insulates and speeds up neural transmission) and forming the blood-brain barrier (which regulates what substances can enter the brain). Option A includes both of these roles. Option B refers to neuronal development, not glial cell roles. Option C is partially correct (glial cells do regulate metabolic activity), but pain detection is typically attributed to specialized neurons. Option D is not accurate - glial cells may play a role in monitoring neural transmission, but they do not release hormones in the brain.
