What type of joint is a fibrous joint?

A fibrous joint is defined as a type of joint where the bones are united by dense connective tissue, specifically fibrous tissue. This structure provides minimal to no movement, which is characteristic of fibrous joints. They are typically found in areas where stability is more important than mobility, such as the sutures of the skull.

This type of joint differs significantly from others. For example, synovial joints, which are highly movable, have a synovial capsule and fluid that facilitate movement, and are not classified as fibrous joints at all. Similarly, joints that are joined by cartilage, such as synchondroses and symphyses, allow for limited movement but are classified differently due to their connective tissue composition. Therefore, the defining characteristic of a fibrous joint being composed of bones united by fibrous tissue is what makes it the correct choice.
