What are the types of joints classified structurally?

Fibrous, cartilaginous, synovial.

What are the two methods of classifying joints?

Structural and functional classification.

What type of joint is a synarthrosis?

What characterizes a diarthrosis joint?

A freely movable joint.

What connective tissue is involved in a synchondrosis?
