Classification of joints

Level 3 certificate in sports

Joints
Joints are located where two bones meet
...
They are 3 types of
joints: fibrous joint, cartilaginous joint and synovial joints
...
This joint is connected by fibrous
connective and is held together by tissues such as tendon but have no joint cavity
...
Cartilaginous joint allows a small
amount of movement to take place, as a result of that cartilaginous joint is also known as
‘slightly’ or ‘partly’ moveable joints
...
The vertebrae
column is one of the examples of a fibrous joint
...
These joints are surrounded by an articular
capsule which contains synovial fluid
...
Synovial fluid lubricates the joints, avoiding the joints from
stiffness and supplying nutrients to the cartilage

Different types of synovial joints
They are 6 different types of synovial joints located in the body: ball and socket joint, hinge
joint, pivot joint, saddle joint, condyloid joint and gliding joint
...
They
allow movement around 3 axes; flexion, extension, abduction, adduction, rotation
...

Example of ball and socket joints can be your shoulders; when you bowl in cricket the ball
and socket joint allows a full 360 degree rotation around your shoulders
...
The movement that takes place at
the hinge joint are extension and flexion
...
When you’re sprinting, the hinge joint in the knee allows movement such as
abduction and adduction to occur
...
Pivot joint allows rotation of one bone around another
...
In a game of football, the pivot joint helps you to header
the ball with your head
...
The only saddle joint in the human body is placed in the thumb
...


Condyloid joint
Condyloid joint allows flexion, extension, abduction and adduction, similar to ball and
socket
...
Examples of
condyloid joint can your wrist
...

Gliding joint
Gliding joints allows gliding movement in all directions
...
An example can also be the wrist
...

...
They consists of articular
cartilage, synovial cavity, a fibrous articular capsule, and ligaments
...
It consists of an outer layer, the fibrous membrane, an inner lining and a synovial
membrane
...
The
ends of the joints are shielded by a flat, glass like hyaline cartilage which decreases friction
during movement
...
The
synovial joint has an irregular connective tissue, which consists of a synovial cavity, which is
basically the gap between 2 articulating bones, and dense, that forms the articular capsule
normally associated with accessory ligaments; ligaments are tough bands of connective
tissue, thickening of the articular capsule that helps provide stability
