The articular units found in synovial joints can be classified structurally as modified or unmodified sellar, modified or unmodified ovoid. A fourfold functional classification can also be made in terms of the chordal, arcuate and rotatory motions (sensu medico) permitted or prevented at them. Each structural class corresponds to one and only one functional class. Two apparent exceptions are explained. The parts played by articular structure and by the musculature in determining the movement(s) at a joint are considered briefly.
