Polyarticular (from the Greek πολύς (polýs) → "a lot"; from the medical terminology "articular" → "concerning the joint"; "concerning several joints") denotes something in medicine that relates to many joints or (like Muscles) acts on several joints.

Application examples

The long tendon of the biceps brachii muscle arises from the joint capsule of the shoulder joint, but also flexes the elbow joint and is therefore biarticular. The long finger flexors and extensors , such as the flexor digitorum superficialis or the extensor digitorum muscle , act on numerous finger joints in addition to the wrist and are therefore polyarticular.

In the case of inflammation of a joint, arthritis , it is important for the differential diagnosis, especially with regard to rheumatic diseases , to distinguish whether only one joint (" monoarticular "), some joints ("oligoarticular"), or many joints ("polyarticular") are affected.
