What does the root 'arthr/o' refer to?

Explanation:
The root arthr/o denotes a joint. In medical terminology, roots carry the main meaning of a body part, and combining forms link that meaning to suffixes to build terms about that part. So arthr/o is used to talk about joints—arthritis describes inflammation of a joint, arthroplasty is surgery to repair or replace a joint, and arthroscopy is the procedure of visually examining a joint. This root does not mean stomach, muscle, or blood vessel—that would be gastr/o, my/o, or vas/o (or angi/o), respectively.
