Glial cells surround neurons and transport nutrients from blood vessels to neurons. Glial cells also
-are involved in the control of large muscle movements
-influence the transmission of messages from one neuron to another across synaptic gaps
-act as the major excitatory cells in the central nervous system
-regulate sleep cycles and dreaming
answer: act as the major excitatory cells in the central nervous system
explanation: glial cells are non-neuronal cells in the central nervous system and the peripheral nervous system that do not produce electrical impulses. Maintains homeostasis, form myelin, and provide support and protection for neurons
