Amphiarthrosis

Amphiartosis

Amphiartosis is a syndrome of dystrophic changes in the musculoskeletal system. With this pathology, there is a complete synovial membrane in the joint. Other components of the joint may also be damaged: cartilage, ligaments, menisci. The worldwide prevalence of the disease is only about 0.02%. Also, amphiartosis should not be confused with arthrosis, in which there is no synovial membrane (fibrous tissue appears instead). The disease also manifests itself in juvenile chronic oligoarthritis and the occurrence of aseptic necrosis of the femoral head. Although diagnosing this disease is difficult, it occurs in 40–50% of patients with this syndrome. The synovial surface is an important element of the articular surface, which prevents bone from dislocating from the joint cavity. Also promotes proper joint movement. It helps smooth out shocks and stress during joint movements, protects, nourishes joints and performs other functions. In addition, synovial fluid refers to the shock absorber between bones. Normally, synovial joints are characterized by smooth, smooth surfaces. If the structure of the joint is disturbed, the range of motion decreases. The synovial membrane secretes both protein-polysaccharide and lipid-protein-carbohydrate substances, which cover the moving synovial surfaces from the inside, giving them smoothness,



Amphiarthrosis: Basics and functions of flexible joints

Introduction:
Amphiarthrosis, also known as amphiarthrosis, is a type of bone joint that allows limited mobility and flexibility. This term comes from the Greek words "amphi" (meaning "both") and "arthrosis" (meaning "joint"), which indicates its characteristic of being intermediate between non-inertia (synarthroses) and fully mobile (diarthrosis) joints. In this article we will look at the basics of amphiarthrosis, their structure and function, as well as several examples of such joints in our body.

Structure of amphiarthrosis:
Amphiarthrosis is characterized by the presence of connective tissue between the connected bones. This connective tissue can be represented by various structures such as cartilage, ligaments or discs. It provides a certain degree of mobility to the joint while maintaining its stability. Amphiarthroses usually do not have the full range of motion found in fully articulated joints, but they do provide enough flexibility to perform certain functions.

Functions of amphiarthrosis:
Amphiarthroses perform several important functions in the body. They allow you to absorb shock and vibration that may occur during movement. This is especially important for joints that are close to the spine, such as intervertebral discs. Amphiarthrosis also contributes to the absorption and distribution of force that occurs during mechanical impact on the joints. They also provide a degree of mobility, allowing the body to adapt to different movement needs.

Examples of amphiarthrosis:

  1. Intervertebral discs: These amphiarthrosis are located between the vertebrae of the spine and serve as shock absorbers, allowing flexibility and shock absorption as the spine moves.
  2. Symphyses: Symphyses are amphiarthrosis that connect flat bones such as the pelvis. They provide the mobility necessary for the birthing process while maintaining bone stability.
  3. Dental joints: The dental joints, also known as gomphosis, are located between the upper and lower jaws. They provide some mobility when chewing and speaking.

Conclusion:
Amphiarthrosis is a type of bone connection that allows limited mobility and flexibility. With their help, the body can perform a variety of motor functions while maintaining joint stability. Examples of amphiarthrosis include intervertebral discs, symphyses, and dental joints.

Although amphiarthrosis does not have the full mobility of diarthrosis, it plays an important role in maintaining the functionality of the body. Understanding the structure and function of amphiarthrosis helps us better understand how our bodies provide flexibility and stability at the joints.
