Neuroglia that control the chemical environment around neurons by buffering potassium and recapturing neurotransmitters are a. oligodendrocytes b. microglia c. astrocytes d. schwann cells

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.

substitution is the answer in this case

c is the correct answer hope this !
