Which term means star-shaped cell?

• A. Arthrocentesis
• B. Arthrodesis
• C. Astrocyte
• D. Atrioventricular

Answer: (C)

The term meaning star-shaped cell is astrocyte. The name comes from astro- meaning star and -cyte meaning cell, pointing to its many radiating extensions that give it a star-like appearance under the microscope. Astrocytes are a type of glial cell in the central nervous system and play key roles in supporting neurons, regulating the extracellular environment, supplying nutrients, and helping form the blood-brain barrier, as well as participating in repair after injury.

The other terms do not refer to a cell type: arthrocentesis is a procedure to withdraw joint fluid, arthrodesis is surgical fusion of a joint, and atrioventricular relates to the heart’s atria and ventricles.
