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.
