Arthrology

Arthrology (or syndesmology) is the branch of anatomy that studies the joints (or junctions) between the different bones of the skeleton.

It describes the structure, function, type, and classification of the various joints according to their mobility and anatomy. These joints can be classified based on their degree of mobility or according to a histological classification.

In the first classification, we find:

• Synarthroses (or immovable joints): allowing limited or no movement, with the intermediate tissues sometimes ossifying over time.

• Diarthroses (or movable joints): which are among the most numerous and allow wide and varied movements.

• Amphiarthroses (or semi-movable joints): representing an intermediate type between the previous two.

In the second classification, we find:

• Fibrous joints: where the interosseous substance is fibrous tissue, resulting in immovable joints.

• Cartilaginous joints: where the intermediate tissue may be fibrocartilaginous or hyaline cartilage, also resulting in immovable joints.

• Synovial joints: provided with a joint cavity and synovial fluid, resulting in movable joints.
