What does the root "-cele" specifically denote in medical language?

The root "-cele" in medical terminology specifically denotes a swelling or cavity. This suffix is commonly used to describe various types of hernias or fluid-filled sacs in the body. For instance, a cystocele refers to a bulge of the bladder into the vagina, and a meningocele describes a protrusion of the protective membranes surrounding the brain or spinal cord through an abnormal opening in the surrounding vertebrae.

Understanding this root is essential for accurately interpreting medical terms related to conditions involving abnormal swellings or cavities, guiding healthcare professionals in diagnosis and treatment. Each of the other options refers to different concepts in medical terminology, but "-cele" is clearly established as relating to swelling or cavity.
