Synarthrosis

-SYNARTHROSIS-

-What are the joints?

Joints are the structures that allow the union between two or more bones of the human body, provide mobility and stability to the body, and are classified according to the amount of movement they allow.

There are different types of joints in the human body, and they are classified according to the amount of movement that allows:

Mobile joints, such as the knee and elbow, allow a lot of movement and are important for performing complex physical activities.

Semi-mobile joints, such as vertebral joints, allow limited movement and provide stability to the body.

Fixed joints, also known as synarthrosis, do not allow movement and are found in areas of the body that need resistance and protection, such as the skull.

-Why joints are important?

Joints are important because they allow movement, provide stability, cushion the impact, protect bones and organs and allow the flexibility and adaptability of the body.

If we did not have joints, we would be limited in our ability to move and our stability, we would experience greater impact force and we would be at greater risk of injury and damage to internal organs.

-what is "Synarthrosis"?

Synarthrosis is a type of union between two bones that has a little or no movement.It is also know as an immobile or fibrous joint that are found in the human body. This joint is composed of a fibrocartilaginous that is a connective tissue that unites some bones and provides stability and support.This type of joint is mainly found in the bones of the skull and in some joints of the teeth and bones of the spine that need protection and resistance to excessive movement. They also are important because allow the bones to develop and grow properly during the process of formation of the human skeleton.

-WHAT ARE THE FUCTIONS OF SYNARTHROSIS?

Synarthrosis, as a group of immobile joints, fulfills several important functions in the human body. Some of the main functions of synarthrosis are described below:

1.Provide stability: The main function of synarthrosis is to provide stability and protection to the internal organs of the body. Synarctic joints, being immobile joints, are very resistant and able to withstand large weight loads without moving.

2.Allow growth and development: Synarthrosis is very important in the process of growth and development of the human skeleton, since they allow bones to fuse and grow properly. For example, skull sutures allow the bones of the head to fuse during the process of formation of the skull.

3.Protect and stabilize adjacent joints: In some parts of the body, such as in the extremities, synarthrosis work as "an anchors" for adjacent mobile joints, providing stability and protection to these joints and reducing the likelihood of injury.

-WHAT TYPES OF SYNARTHROSIS EXIST?

There are three main types of SYNARTHROSIS:

1.Fibrous joints or sutures: These joints are formed by fibrous tissue and are typically found in the bones of the skull. They are immovable joints that provide stability and protection to the brain 2.Cartilaginous joints or synchondrosis: These joints are connected by cartilage, which allows for some flexibility during growth but eventually becomes fused together. Examples of synchondrosis joints include the epiphyseal plates in long bones and the joint between the first rib and the sternum. 3. Bony joints or synostosis: These joints are formed when two bones fuse together and become one bone. An example of synostosis is the fusion of the three bones that make up the hip bone during childhood.
