Types of Fibrous Joints
Fibrous Joints are divided into three types: Sutures, Syndesmoses, and Gomphosis.
Sutures
A suture on the skull is a specific kind of joint, and it’s made out of fibers. It is found only in the skull, and it holds its bony plates together. The Sharpey’s fibers tissue originate from each bone and links it with its neighbor attaching the sutures. The slight movement of the sutures makes the skull flexible. These bones have very little movement, so they’re known as immovable joints.
Syndesmoses
Syndesmos are joints by stretchy ligaments and bones that allow some movement. An interosseous membrane tissue between bones plays an important role in setting up compartments, absorbing impacts, and separating joints. E.g. The interosseous membrane divides muscle in a leg between the tibiae and fibula and stabilizes bones around the elbow.
Gomphosis
The gomphosis is a special type of joint that allows teeth to be inserted in their sockets at the upper and lower jaw. It allows very little movement. The new teeth have gonemphoses of their own that keep them together as they grow and lose baby teeth. The gomphosis is made of hard tissue called ligaments which are attached to the tooth’s base and socket. When people grow old, their new teeth develop gomphoses that keep them in the mouth.
Fibrous Joints – Examples, Diagram, Function & Movement of Joint
Fibrous Joints are joints formed by fibrous tissue, like collagen. These are also called fixed or immobile joints as there is no movement. The hard tissue with a lot of collagen fibers connects the fibrous joints. There are different types of fibrous joints such as sutures, fontanelles, synostosis, syndesmoses, etc. The skull is the best example of a fibrous joint. The skull is the most common example of a fibrous joint. Other examples of fibrous joints are the spine, pelvis, rib cage, and upper jaw. Fibrous joints are strongly attached to adjacent bones and provide protection to internal organs, strength to the body regions, and weight-bearing stability.
