What type of glial cell acts locally to maintain normal electrolyte composition of the cerebrospinal fluid?
nikitadnepr [17]

Answer:

Astrocytes

Explanation:

Astrocytes are specialized glial cells found in the brain and spinal cord, they are responsible for maintaining the electrolytic composition of the cerebrospinal fluid, induce the formation of the blood-brain barrier and act as a support and guide for neurons during migration. They keep the ionic composition of the extracellular fluid of the central nervous system through the water channels, Aquaporin-4 (AQP4) and K channels, located in the pedicle processes of the astrocytes in the perivascular space, these cells exchange K and water in said perivascular medium away from the neurons. Astrocytes selectively edematize during hypotonic stress, while neurons do not.

The tree of life basically determines which organism has evolved from which other organisms.  

The biological ladder represents the development of species from simple form to a much complex form.
