Answer:
Astrocytes
Explanation:
Astrocytes are star shaped glial cells and are the most abundant glial cells in the group. Thy have gap junctions with pottasium and calcium channels that refulate the concentration of the ions in the environment creating a buffer that ensures the neurons function effectively during saltatory condution when ions are released outside their membrane. They also capture any unused neurotransmitters during cell communication by neurons at the synaptic junctions.
