Fibrous Joint

A Fibrous Joint (pronunciation: /ˈfaɪbrəs dʒɔɪnt/) is a type of joint in the human body that is connected by fibrous connective tissue. The etymology of the term comes from the Latin word "fibra" meaning fiber and the Old French word "joint" meaning to join.

Definition

A Fibrous Joint is a type of anatomical joint that is characterized by the lack of a joint cavity and the presence of fibrous connective tissue. The bones in these joints are held closely together by fibrous tissue, which is rich in collagen fibers. This type of joint is immovable or only slightly movable, providing stability and strength.

Types

There are three main types of Fibrous Joints:

• Suture: These are found only in the skull and allow for growth during childhood. In adulthood, the sutures become ossified, forming a nearly immovable joint.

• Syndesmosis: This type of joint is found between long bones of the body, such as the radius and ulna in the forearm or the tibia and fibula in the leg. They are held together by a sheet or bundle of fibrous tissue.

• Gomphosis: This is a specialized fibrous joint in which a conical process or peg fits into a hole or socket, as in the case of teeth fitting into the jawbone.
