Joint(s): 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. 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. The three structural classifications include fibrous,
cartilaginous and synovial. The three functional classifications include synarthrosis, amphiarthrosis and
diarthrosis. Joints can also be classified biomechanically and these include simple, compound and complex.
Joint Mice: Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of
the bone beneath it, comes loose from the end of a bone. Once separated these small fibrous, cartilaginous, or
bony loose bodies freely float in the synovial cavity and are known as joint mice.
Joint Motion: Joint motion refers to the distance and direction a joint can move to its full potential. Each specific
joint has a normal range of motion that is expressed in degrees after being measured with a Goniometer.
Joint types: There are six types of joints in the human body. They include ball and socket, gliding, hinge, saddle,
condyloid and pivot joints.
