Answer:
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.
The two roles of glial cells are:
a. acting as insulation and providing structure to surrounding neurons.
e. increasing the speed of neural transmission and regulating metabolic activity.
Glial cells are also called as neuroglia, are the non-neuronal cells that are present in the central and peripheral nervous system.
They provide physical and metabolic support to the neurons.
They do neuronal insulation, their nutrients and waste management.
Thus, the correct options are A and E.
