## Definition

a type of joint in the body that can move freely. You use this word when talking about anatomy to describe joints like your shoulder or hip.

For teachers: an articulation or joint that allows for free movement between bones. Often used as a synonym for a diarthrodial joint in anatomical contexts.

## Examples

- The shoulder is a common example of an abarthrosis.
- The surgeon examined the abarthrosis to determine if the cartilage damage was affecting the joint's range of motion.
- While most joints in the skull are fixed, the jaw functions as an abarthrosis, allowing for the complex movements required for mastication and speech.

## Usage notes

- Primarily used in medical and anatomical contexts; less common in modern clinical practice than the term 'diarthrosis'.
