The joints of the human body are called “joint” in English and “articulation” in Latin. In anatomy, they refer to the connection points between two or more bones. Joints allow human bones to move.
In the process of preparing for the MBLEx federal massage exam, the classification of joints is varied and has always been a difficult point for students to learn. Therefore, today I will explain the types of joints to you all at once , so that you can have a general idea in your mind and be more confident when you encounter questions about “joints”.
Without further ado, let’s get started!

The joints of the human body can be divided into three types according to their function:
synarthrosis
amphiarthrosis
diarthrosis movable joints (fluid in the joints – synovial fluid)
The names of these joints seem difficult to remember, so let’s first look at their common suffixes:
-arthrosis
It has two meanings:
First, it indicates the joints between bones;
Second, it indicates degenerative joint diseases.
So, from now on, when you see a word with the suffix -arthrosis, you will know that it must be related to joints.
synarthrosis
syn-, this prefix means “together”
Synchronous means “synchronous”
When the two bones connected by a joint move “together” and “synchronously”, the joint is called a “fixed joint”.
amphiarthrosis
amphi means “both”
Amphiarthrosis means a slightly movable joint, also called a cartilaginous joint or a double joint.
diarthrosis movable joints or articulations
Also called movable joint
There are gaps between the bones of the movable joints, which contain synovial fluid. When the joint surfaces contact and slide against each other, the friction coefficient and wear can be reduced to a minimum.
The above three types of joints are divided according to their functions. If divided according to their structures, joints can be divided into the following three types:
The first type: Synovial joint
Also known as “synovial joint” or “diarthrosis”
Synovial joints are the most common joints in the human body. They are filled with fluid and connected to adjacent bones by a fibrous joint capsule.
Synovial joints are divided into the following types based on their shape:
ball-and-socket joint
Saddle-joint
Sliding joint
Hinge joint
Elliptical joint
pivot joint
condylar joint
The second type: Cartilaginous joint
A cartilaginous joint is a joint where bones are connected entirely by cartilage. Cartilage includes hyaline cartilage and fibrocartilage. Cartilaginous joints usually move more than fibrous joints, but less than synovial joints.
The third type: Fibrous joint
Fibrous joints are joints in which adjacent bones are tightly connected by thick connective tissue.
There are three types of fibrous joints:
(1) Suture joint
Suture joints are immovable joints that connect the skull bones. These joints have serrated edges and are locked together by connective tissue fibers.
(2) Gomphoses or nail-like joints
The fibrous joints between the teeth and the mandible or maxilla are called chimeric or peg joints and are also immobile.
(3) Syndesmoses or syndesmoses
A joint in which two bones are connected by ligaments, allowing very little movement (a micro-motion joint). The distal joint between the tibia and fibula is an example of a syndesmosynostosis joint.
in:
Synovial joints are diarthrodial joints;
Cartilaginous joints are micro-motion joints;
Fibrous joints are immobile joints.
How about it? After reading this, do you have a general understanding of the classification of joints?
As we all know, the current MBLEx federal exam questions are all centered around knowledge points, and the questions are constantly changing. If you focus on the questions to remember the answers, you will be helpless if the questions are slightly changed.
Therefore, Yibei’s teaching method has always been to start with knowledge points and respond to changes with the same approach. As long as you understand the knowledge points, we are not afraid of any changes in the questions.
