What are two roles of glial cells?
a. acting as insulation and providing structure to surrounding neurons
b. shaping cells and moving new neurons into place
c. regulating metabolic activity and serving as pain detectors
d. monitoring neural transmission and releasing hormones in the brain
e. increasing the speed of neural transmission and regulating metabolic activity

The correct answer will be options A and E.

Explanation:

Glia cells or neuroglia are the non-neuron cells present in the nervous system which performs functions other than transmission.

These glia cells like Schwann cells form the myelin sheath around the neuron which insulates the neurons, increasing the transmission of the impulse. They help protect the neurons from pathogen as microglial cells act like macrophages.  They help in maintaining the neurons like ependymal cells which provide nutrition to the neurons.

Thus, options A and E are the correct options.
