Joints
Fibrous Joint
The fibrous joints in the skeletal system are joints that are fixed or immovable. An example of the fibrous joints are the joints in the skull. The coronal structure is a fibrous structure which connects the parietal and the frontal bones of the skull.
Cartilaginous Joint
Cartilaginous joints are partially movable joints consisting of synchondroses joints. Synchondroses joint is an almost immovable joint between bones bound by a layer of cartilage, as in the vertebrae. Some examples of cartilaginous joints are the rib cage and the spinal column.
Ball-and-Socket Joint
Ball -and-Socket joints are ball shaped joints which help bones move in the body. Examples of these joints are the hip and shoulder joints. The ball-and-socket joint allows freedom of movement up, down, right, left and in a full 360-degree rotation.
Saddle Joint
Saddle joints are joints that allow movement on two planes. The allow flexing/extension and abduction. The one and only example of a saddle joint is the thumb in the human body.
Hinged Joint
Hinged joints are joints that allow movement in only one plane. Some examples of hinged joints are the elbows and the knees because they can only move in one direction; the elbow move inwards towards the human body and the knee moves towards the back side of the human body.
Gliding Joint
Gliding Joints let two or more flat or maybe a little bit rounded joints to move smoothly. Some examples of the gliding joints are are the ankle joints and the wrist joints because they can move very smoothly surpassing friction.
Pivot Joint
Pivot joints are joints that consist of a cylinder inside a circular ring which allow bones to rotate. Some examples of these joints are the wrist joint and the base of the skull. This is allows the head and hand of the human body to rotate.
Condyloid Joint
Condyloid joints allow joints in the human body to move upwards, downwards and side to side. Some examples of these joints are the wrist joint and the ankle joint, this is because both these joints have the ability to move up, down, and side to side.
