A **joint** is the location at which two or more bones make contact.[1] They are constructed to allow movement and provide mechanical support, and are classified structurally and functionally.

Classification
Joints are mainly classified structurally and functionally. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. In practice, there is significant overlap between the two types of classifications. Terms ending in the suffix -sis are singular and refer to just one joint, while -ses is the suffix for pluralization.

Structural classification
Structural classification names and divides joints according to how the bones are connected to each other.[3] There are three structural classifications of joints: Fibrous joints Cartilagnus joints Synivial joints

Functional classification
Joints can also be classified functionally, by the degree of mobility they allow:[4]
 * Diarthrosis
 * Amphiarthrosis
 * Synarthrosis
