In fact not only fitness people, anyone often deal with joints and ligaments. It is just more important for fitness people to understand them, because improper use can cause injury. Perhaps the term ligament is slightly unfamiliar to some people, but hearing the word joint should not be unfamiliar at all, then you can say the general composition of the joint?
A joint is where two bones meet and movement occurs at the joint. The main structure of a joint consists of the joint surface, the joint cavity and the joint capsule. The joints are connected by a transparent cartilage, which is a smooth and tough substance. With it, one part of the joint can slide or move smoothly over the other part.
The joint capsule is a thick, fibrous, enclosed space that wraps around the joint while tightly attaching to ligaments. The ligaments are strong and are fibrous bands that connect two bones. Ligaments are dense connective tissue. There are two main types: elastic connective tissue and irregular dense connective tissue made of collagen fibers intertwined with each other. Ligaments help to hold joints in place, allowing movement within the normal range of function while preventing abnormal joint movement.
In contrast to the active stabilizing effect of muscles and tendons, both the joint capsule and ligaments passively stabilize joint tissue. In addition to providing power, the muscles and tendons at one end of the joint can actively stabilize the joint, and in combination with the muscles and tendons at the other end of the joint can limit the motion of the joint.
Ligament injuries can occur from direct impact by a blunt object, causing a contusion, or from a sharp object, causing a cut. Ligament injuries can also originate from excessive forces that cause injury to the ligament itself or to the ligament attachment site. Such ligament injuries are often referred to as sprains.
