Joint Flat (Arthrodic Joint, Gliding Joint)

Joints are the connections between bones in our body that allow us to move and perform various functions. There are several types of joints, one of which is the Gliding Joint, also known as the Arthrodic Joint or Gliding Joint. In this article we will look at this type of joint, its structure, functions and examples in our body.

Structure of the Flat Joint

The flat joint is a type of diarthrosis - a freely moving joint in which the flat articular surfaces of the bones slide over each other without making angular or rotational movements. This type of joint has minimal ligaments and capsule, allowing it to be more mobile than other types of joints.

Functions of the Planum Joint

The planus joint performs a number of important functions in our body. It allows movement between the bones it connects, which helps us perform various movements such as bending and turning. This type of joint also provides stability to the bones it connects and reduces the risk of injury when moving.

Examples of the Flat Joint in our body

There are several examples of the Joint Planum in our body. One of the best known examples is the intercarpal joints, which connect the radius and ulna to the carpal bones. Additionally, the sacroiliac joint is also an example of the Joint Planum as it allows movement between the sacrum and the ilia.

Similar joints can also be found in the feet, including the joints between the big toe and metatarsal bone, and between the metatarsals. These joints play an important role in maintaining stability and mobility of the foot.

In conclusion, the Planus joint is one of the types of joints in our body that provides movement and stability between bones. Due to its structure and functions, the Planum joint is an essential element for performing many movements in our body.

The planum joint is a type of diarthrosis in which two bones slide over each other without making angular or rotational movements, making it one of the simplest types of joints. This type of joint is found in various parts of the body, including the intercarpal, sacrolumbar, and intermetatarsal joints.

The flat joint differs from other types of joints in that it does not have a surface that can be fixed or locked. Instead, the two bones move relative to each other without locking or fixing. This allows the joints to move easily and freely, which is an important factor in various body movements. For example, the intercarpal joint allows the arms to flex and extend easily, while the sacrolumbar joint provides flexibility to the spine and the ability to bend forward and backward.

However, despite its simplicity and ease, the Flat joint also has its limitations. It is unable to make angular or rotational movements and cannot withstand heavy loads. Therefore, this type of joint is used in cases where easy and free movement is required, but not much strength or stability is required.

In conclusion, the Planum joint is an important element of our body and plays an important role in our ability to move and perform various activities. However, it must be remembered that each joint has its own characteristics and functions, and the choice of joint type should be based on the specific requirements and tasks to be performed.

In this article we will look at the concept of a hinged connection of skeletal elements. A hinge joint is a connection of any two points of a plane in which two points of intersection with the plane pass through one point in this plane. The existence of mobility of various types of articulated joints is very important for vertebrates, since it provides free choice of body position relative to the surface. Some animals have jointed legs called flippers, which enable them to move through the water very easily, somewhat reminiscent of the feet of a seal.
