Sutures are only found in the skull.
Sutures are classified as a Fibrous joint - and permit no movement.
Sutures are connected by fibro cartilage.
Fibrous cartilage is made up of dense irregular connective tissue.
Hyaline cartilage normal covers the articular surfaces of bones in typical synovial joints and primary cartilaginous joints. Certail joints do not have hyaline cartilage covering the bony elements. These include: 1. Fibrous Joints - skull sutures, gymphosis (teeth) and interosseus joints (radius and ulna shafts) 2. Atypical Synovial Joints (these have fibrocartilage instead of hyaline cartilage covering the bones). These include the Temporomandibular (TMJ), Acromioclavicular Joint (ACJ), Sternoclavicular Joint, and 2nd to 7th Sternocostal Joints.
a. joined by fibrous tissue b. joined by hyaline cartilage c. ossify as you get older d. they are all examples of sutures
A symphysis and a syndesmoses are both types of non-synovial joints in the body. A Syndesmoses is a dense fibrous tissue joint, which is completely immobile (like the joints in the skull before they become sutures, the inferior tibiofibular joint, or the tooth filling in a tooth socket.) A symphyses is a joint where the opposing surfaces of bone are covered in hyaline cartilage but instead of having synovial fluid between then there is a plate of fibrocartilage. (this is like the pubic symphyses, intervertebral discs, joint between sternum an dmanubrium) You can compare these two non-synovial joints with a third, which is a synchondrosis, made completely of hyaline cartilage, like the cartilage that connects the 1st rib with the sternum.

"sutures"
Sutures are immovable, wavy joints between the bones of skull.
There are eight sutures in the human skull. These sutures are fibrous joints that connect the bones of the cranium and allow for slight movement during childbirth and growth. Some examples of skull sutures include the sagittal suture, coronal suture, and lambdoid suture.
When we are babies, our bones are very soft. They are cartilage. As we get bigger our cartilage gets hard, and turns into bone. This is caused from the calcium that is being dumped into the cartilage as we get older. In babies, the skull bones do not connect with sutures for a long time and is still soft, until about a year old.
Cartilage from the cleft side is freed from the opposite side, and is positioned and reshaped using nylon sutures.
sutures
bones of the skull are connected by sutures which are fibrous joints. sutures are important because they allow bones of the skull to move during birth. Also, to allow bones of the skull to grow as the brain enlarges.
The "sutures" are fibrous (immovable) joints between the plates of the skull, which must expand apart with age.
