What is the medical term for inflammation of the vermiform appendix?

The medical term for inflammation of the vermiform appendix is "appendicitis." This condition occurs when the appendix, a small tube attached to the large intestine, becomes inflamed, often due to a blockage, infection, or other factors. Appendicitis is characterized by symptoms such as abdominal pain, typically starting around the navel and then shifting to the lower right abdomen, nausea, vomiting, and fever.

In contrast, cholecystitis refers to inflammation of the gallbladder, which is unrelated to the appendix. Hemorrhoids are swollen veins in the lower rectum or anus and do not involve the appendix at all. A cyst is a general term for a closed sac-like structure that may contain fluid or semi-solid material but does not specifically denote inflammation or pertain to the appendix.

Therefore, "appendicitis" specifically refers to the inflammatory condition of the appendix, making it the correct medical term for the scenario in question.
