Summary about the joints of the human body

Introduction (what it is and types of joints)

The articular system is formed by joints, ie, a point of contact between the bones.

Throughout our body we have different types of joints: some that are quite strong and immobile (known as synarthrosis) and others that allow movements because they are flexible (anfiarthrosis and diarthrosis).

Structure (classification)

Regarding their structure, the joints can be classified into fibrous (bones are joined by fibrous connective tissue), cartilaginous (bones are joined by cartilage) and synovial (has a space between bones).

Our body is capable of many movements, however, these movements cause friction. To alleviate this friction, our joint system relies on synovial pockets.

These bags act as shock absorbers between the joints. They are located between the skin and the bone (in the regions where friction occurs between these parts), between the tendons and the bones, between the muscles and the bones and also between the ligaments and the bones.

Effect of aging on joints

With advancing age, the production of synovium in the joints is reduced, and from this point on the effects of aging in the joints begin to appear, which can be increased by both genetic factors and wear.

Did you know?

- In the past, joints were known as the joint, hence the expression "joint pain".
