Practice question

The correct answer is C: Astrocytes. In Endocrinology, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, the functional job described in the stem is exactly what Astrocytes does in Endocrinology. That is why Astrocytes is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Astrocytes.
