Meaning of Joints
What are Joints:
Joints are the anatomical tissues that facilitate mechanical movements, provide elasticity and serve as a link between bones, bones and cartilage or between bone tissue and teeth.
The main functions of the joints are to keep the bones of the skeleton together and in this way facilitate the movement of the body, therefore, we can walk, sit, run, talk, do things with our hands, among many other activities.
Therefore, the joints, in conjunction with other important tissues, allow the movements of the neck, knees, arms and shoulders, fingers and toes, hips, among others, with the exception of the bones that they form the skull, which although they are made up of joints, their movement is almost nil.
Types of joints
The human body is made up of 360 joints, which are classified according to their composition and the movements they allow to perform.
Joints according to their composition
Fibrous: they are the joints that are made up of collagen fibers.
Cartilaginous: they are the joints that are made up of cartilage bands that connect to the bones.
Synovials: These joints are connected by dense, irregular tissue that forms a capsule with a fluid that allows the bones to articulate.
Joints for their movement
Synarthrosis: these are immobile, rigid joints. These joints are held together by bone growth or cartilage. Examples of these joints are the bones that make up the skull, the nose, among others.
Amphiarthrosis: these are the joints that can perform slight movements and are characterized by being cartilaginous. These joints are at the junction of the bones of the spine.
Diarthrosis: these are the joints that can perform the greatest amount of movements and that there is more in the body.
Through these joints, movements of flexion and extension, displacement, twists, lateral and medial rotation, abduction, circumcision, among others, can be performed.
