What type of joint is described by the term amphiarthrosis?

Amphiarthrosis refers to a type of joint that allows for limited movement between the bones it connects. This classification indicates that the joint can provide some degree of flexibility while still maintaining structural integrity. Common examples of amphiarthrotic joints include the intervertebral discs in the spine and the pubic symphysis, where the bones are connected by cartilage that permits slight movement.

The term itself derives from Greek roots; "amphi-" meaning "on both sides" and "arthrosis" meaning "joint." This reflects the partial mobility characteristic of these joints, distinguishing them from other types of joints. Immovable joints, completely movable joints, and fixed joints each represent different classifications that do not align with the definition of amphiarthrosis, which specifically emphasizes a moderate range of motion.
