Bones and rheumatism

What type of elbow joint?

The human body consists of a group of bones, which form the skeleton that helps the human body perform many movements such as walking, running, and the ability to move things and other movement activities. The skeleton consists of 206 bones, and the number of joints in the human body is 220 joints. A joint is a point where one bone meets another bone, that is, the dividing point that connects the parts of the skeleton.

Joints in the human body have been classified into several types, namely: fibrous joints, cartilaginous joints, and serous or synovial joints. The reason for the diversity of joints is due to the type of tissue that connects the bones. We also point out that the joints are fixed, even if they were mobile, the skeleton would be lost. Its stability and shape, and the stability of the joint is controlled by the shape of the joint. An example of this is: the hip joint is a stable joint because it enters the cavity of the pelvic bones. Ligaments also control the stability of the joint because they work to protect it from sudden movements. As for the muscles, they are considered the most important, as they are the ones that surround the joints and stabilize and move them. .

We are certain that joints are important in the human body. It helps in the stability and movement of the skeleton, and the joint is no less important than other joints, and here we will talk about the type of joint found in the elbow or elbow. As we talked above about the types of joints, and in more detail we will talk about the type of joint to which the elbow joint belongs; It belongs to the synovial joints, and this joint is the most common type in the human body, and it is divided according to the type of movement it allows the joint, which are three types:

  • Ball joint: It is the most free to move in all directions, and moves in several axes, such as: the hip and shoulder joint.
  • A joint that moves in only two axes or directions, such as the wrist joint of the hand.
  • The hinge joint: It is the one in which the joint moves in only one axis, such as flexion and extension movements, and it is the most detailed type to which the elbow or elbow joint belongs.

So, the elbow joint or elbow is of the synovial type, which connects the upper end of the radius or ulna and the lower end of the humerus. The elbow joint contains cartilage and a serous membrane, that is, a viscous synovial liquid substance similar to egg fluid. It also contains ligaments that allow the performance of two movements, namely flexion by The biceps muscle, the extending movement is through the triceps muscle, and more similar to the movement of the hinge joint, as it is exactly like the movement of a door when it is opened and closed. The pressure that the elbow joint bears is estimated at one hundred and thirty-five kilograms, which is a fair pressure. Therefore, more training is done to withstand higher pressure in weightlifting, where the pressure that the body can bear reaches two hundred kilograms or more, depending on the weight of the human body, the training that the person undertakes, and the strength of the body.
