What is the meaning of the root word 'ankyl/o'?

The root word 'ankyl/o' specifically refers to a stiff joint or the abnormal adhesion and rigidity of articulating surfaces. It is derived from the Greek word "ankylos," which means crooked or bent, and it is commonly used in medical terminology to describe conditions that lead to stiffness in joints, such as ankylosing spondylitis. This term is pivotal in understanding various orthopedic and rheumatologic conditions, allowing healthcare professionals to communicate about joint health and mobility issues effectively.

In contrast, the other options pertain to different medical terms. For example, 'inflammation' might relate to conditions ending in '-itis,' while 'swelling' could be described by terms like 'edema.' The word 'joint' on its own lacks the specific connotation of stiffness that 'ankyl/o' provides. Thus, the correct answer reflects the distinct meaning associated with the root word, focusing on joint stiffness.
