Bone & Joints

What is Bone & Joints

A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide mechanical support, and are classified structurally and functionally
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 There are three structural classifications of joints:

fibrous joint - joined by fibrous connective tissue
cartilaginous joint - joined by cartilage
synovial joint - not directly joined

Functional classification
Joints can also be classified functionally, by the degree of mobility they allow.

synarthrosis - permits little or no mobility. Most synarthrosis joints are fibrous joints .
amphiarthrosis - permits slight mobility. Most amphiarthrosis joints are cartilaginous joints .
diarthrosis - permits a variety of movements. All diarthrosis joints are synovial joints and the terms "diarthrosis" and "synovial joint" are considered equivalent by Terminologia Anatomica.

Biomechanical classification
Joints can also be classified based on their anatomy or on their biomechanical properties. According to the anatomic classification, joints are subdivided into simple and compound, depending on the number of bones involved, and into complex and combination joints:

Simple Joint: 2 articulation surfaces
Compound Joint: 3 or more articulation surfaces
Complex Joint: 2 or more articulation surfaces and an articular disc or meniscus
