What are the 3 types of fibrous joint?

Answer 1

i) Fibrous (synarthrodial): Fibrous joints are fixed or immovable joints. There are three types of fibrous joints: gomphosis, suture, and syndesmoses. A gomphosis joint is when one bone fits into another bone. The edges are bound together by connective tissue. An example of a gomphosis joint is a tooth in the jawbone. A suture joint. An example of a suture is the fibrous joints between the bones of the skull of an infant. An syndesmoses joint connects two bones through connective tissue. An example is the tibio-fibular syndesmoses, the connective tissue that binds the ends of the fibula and tibia. 　

ii) Cartilaginous: (synchondrosis and symphysis): These are partly moveable joints where the bones are attached by either fibro cartilage or hyaline cartilage. There are two types of Cartilaginous joints: Synchondrosis, which are temporary joints and symphysis which are permanent joints. A synchondroses is a joint where the surfaces are close together, yet are bound by hyaline cartilage. An example of a synchondroses is at the ends of long bones. An example of a symphysis joint is the attachment of one vertebra to another by an intervertebral disk, a fibrocartilage ring, in the vertebral column. This maintains stability. 　 　

iii) Synovial: (diarthroses) Synovial joints are freely movable joints. They all have a synovial capsule (collagenous structure) surrounding the entire joint, a synovial membrane (the inner layer of the capsule) which secretes synovial fluid (a lubricating liquid) and cartilage known as hyaline cartilage which pads the ends of the bones. There are 6 types of synovial joints. They are defined by the shape of the joint and the movement they provide. Synovial-type joints can be further classified into three categories: uniaxial, biaxial, and triaxial.

Examples of these joints range from the joint in the elbow to the thumb.

Answer 2

The three types of fibrous joints are sutures, syndesmoses, and gomphoses. Sutures are immovable joints found between skull bones, syndesmoses are slightly movable joints held together by ligaments like those between the tibia and fibula, and gomphoses are immovable joints found between teeth and their sockets.

The three fibrous joints are the gomophosis, the suture, and the syndesmoses. If you want to know the functions of these joints, go to the link below.
