amfiartroosid

Amfiartroosid, also known as amphiarthroses, are a type of cartilaginous joint found in the human body. These joints are characterized by the presence of fibrocartilage that connects the articulating bones. Unlike synarthroses (immovable joints) or diarthroses (freely movable joints), amfiartroosid allow for a limited degree of slight movement. This moderate mobility is a key feature distinguishing them from other joint classifications.

The primary function of amfiartroosid is to provide a balance between stability and flexibility. The fibrocartilage acts as a shock absorber and allows for some degree of compression and slight rotation or gliding. This makes them suitable for areas where considerable strength is required, along with the ability to withstand some movement.

Examples of amfiartroosid include the pubic symphysis, which connects the two pubic bones in the pelvis, and the intervertebral joints (or symphyses) between the bodies of adjacent vertebrae in the spinal column. The pubic symphysis allows for slight widening during childbirth, while the intervertebral joints permit the spine to bend and twist to a limited extent, contributing to overall spinal flexibility and resilience. The structure of the fibrocartilage in these joints is crucial for their functional properties, enabling them to endure significant forces while allowing for subtle adjustments in position.
