The movement of limbs and the stability found in the bones of the skull are caused by joints.
On the basis of their structure or function, there are two ways to classify joints.
Depending on the material of the joint and the presence or absence of a cavity in the joint, the joints are divided into five categories.
Most fibrous joints are only capable of minor movements because there is no space between the bones.
There are three types of joints.
Sutures are only found in the skull.
An example of a syndesmosis is the ankle joint.
The amount of movement in these joints is determined by the length of the fibers.
The tooth is connected to theemporomandibular joint.
There are joints between the teeth and sockets called gomphoses.
Sympathetic joints and synchondroses are the two types of cartilaginous joints.
The epiphyseal plates are where bones grow in children.
Symphyses can be found at the joints.
This space is filled with fluid from the joint.
The fluid lubricates the joint and allows for more movement.
The ends of the bones are covered with articular cartilage, a hyaline cartilage, and the entire joint is surrounded by an articular capsule that allows movement of the joint while resisting dislocation.
The bones are held together by the ligaments in the articular capsule.
The more mobile a joint, the weaker it is.
synovial joints include knees, elbows, and shoulders.
There is only one joint that has a space in it.
There are three categories of joints: synarthroses, amphiarthroses, and diarthroses.
sutures, gomphoses, and synchondroses are included.
Different types of movements can be produced by the wide range of movement allowed by the synovial joints.
The movement of the joints can be classified into four different types.
There is very little rotation or movement of the bones.
gliding movements can be produced by the joints of the carpal and tarsal bones.
There are several different types of movements.
The forearm can be moved upward at the elbow or the wrist can be moved to the forearm.
Straightening a limb is an example of extension.
If you want the hand to move away from the forearm, you have to move the neck back or bend the wrist.
Abduction is moving the arms or legs to the side.
An example of adduction is the movement of limbs after abduction.
The head moving from side to side is an example of rotation.
Special movements are movements that are not classified as gliding, angular, or rotational.
The jaw is thrust outward and back inwards in the movement of the mandible.
The shape and structure of the joint are used to classify synovial joints into six different categories.
The type of movement allowed by the joint depends on the shape of the joint.
These joints are called condyloid, saddle, or ball-and-socket joints.
Different types of joints allow different types of movement.
synovial joints include planar, pivot, condyloid, saddle, and ball-and-socket.
The joints are referred to as gliding joints because they allow for gliding movements.
The range of motion in these joints is limited.
The planar joints are found in the carpal bones in the hand and the tarsal bones of the foot.
The carpal bones in the wrist are examples of planar joints.
In this way, one bone moves while the other remains stationary.
A hinge joint is an example of the elbow.
The knee can be classified as a modified hinge joint.
The elbow joint is an example of a hinge joint.
The structure allows the rounded bone to move around its axis.
An example of a pivot joint is the neck joint that allows the head to move back and forth.
The pivot joint of the wrist allows the palm of the hand to be turned up and down.
A pivot joint is a joint in the neck that allows the head to move back and forth.
This is called an ellipsoidal joint.
The joints of the wrist and fingers allow movement along two axes, which can move both side to side and up and down.
The metacarpophalangeal joints in the finger are condyloid joints.
Similar to condyloid joints, saddle joints have a greater range of motion.
The thumb is an example of a saddle joint.
All movement types are possible in all directions, as this organization allows the greatest range of motion.
The shoulder and hip joints are examples of ball-andsocket joints.
A ball-and-socket joint is an example of a shoulder joint.
