Verified step by step guidance

Begin by understanding the role of glial cells in the central nervous system. Glial cells provide support and protection for neurons, and each type has distinct functions.

Identify the key function mentioned in the problem: forming the blood-brain barrier. This barrier is crucial for protecting the brain from harmful substances in the bloodstream while allowing necessary nutrients to pass through.

Consider the shape described in the problem: star-like. This characteristic is important for identifying the specific type of glial cell.

Review the types of glial cells listed in the options: Astrocyte, Microglia, Ependymal cell, and Oligodendrocyte. Each has unique functions and structures.

Astrocytes are known for their star-like shape and their role in forming the blood-brain barrier. They extend their processes to blood vessels and neurons, contributing to the barrier's structure and function.
