Joint, in anatomy, a structure that separates two or more adjacent Bone elements. Depending on the type of partnership, such separate components may or may not move. This article deals with the joints of the human body—especially their structure, as well as ligaments, nerves and blood supply, and nutrition. Although the discussion focuses on the human joint, the content is applicable to joints in general and mammals in particular. For information on diseases and injuries that commonly affect the joints,
To describe the types of joint systems, it is first necessary to summarize the possible movements of the joints. These movements include rotation, swing, gliding, rolling, and approximation.
Rotation is the movement of a bone around its long axis; It is an anatomical form of the word

. An important example of rotation is given by the radius (outer bone of the forearm); This bone can rotate at the bottom of the humerus (upper arm) in any position at the elbow. When a person presses the back of the hand to the mouth, the arm is tilted, or twisted; when the palm is placed over the mouth, the arm is flat or does not rotate. Pronation is the result of medial (inward) rotation of the radius and supination is the result of lateral (outward) rotation.
The swing causes a change in the angle between the long axis of the moving bone and the reference line of the fixed bone. Flexion (bending) and extension (straightening) of the elbow are examples of swing. Abduction (to the right or to the left) of one bone moving away from another is called abduction; the reverse, adduction.
Approximation refers to movement caused by pushing or pulling one bone directly onto another—that is, by “translation” in the physical sense. The opposite of approximation is separation. Only within the synovial joint are sliding and rolling motions that result in moving bones.
If taken in time, the joints are temporary or permanent. The bones of the joints fuse sooner or later, but always after birth. All joints, for example, pass except for the middle ear and the one between the lower jaw and the brain. Permanent joint bones do not fuse together except as a result of disease or surgery. Such fusion is called arthrodesis. Some permanent and temporary joints allow movement. Movement of the latter can be temporary, as in the bones of the skull during birth, or permanent, as in the joints of the base of the skull during development. postnatal.
Biology, Animal Structure And Function, The Musculoskeletal System, Joints And Skeletal Movement
There are two basic structural types of joints: diarthrosis, which contains fluid, and synarthrosis, which does not contain fluid. All diarthrosis (often called synovial joints) are permanent. Some synarthroses are transient; Others are permanent. A joint is the point where two bones meet. There are three types of joints: fixed joints, small movable joints, and movable joints.
Ankylosing spondylitis is a joint that does not move as a child grows into adulthood, and separate bones fuse together.
Examples: Cranium: the fused bones covered by your skull; coccyx (coccyx): the fused bones at the base of your spine.
Example: Between the vertebrae. These joints are covered by a spongy disc that can break the op and release the shock gel inside. Such a herniated, ruptured, or “slipped” disc can cause inflammation of the surrounding tissue and various types of pain.

For example: knees, shoulders, fingers. Over time, if the mobile joints are damaged or injured, the fluid between the bones becomes prone to accumulation of tiny gas bubbles. The bursting of these bubbles when the joint moves causes an audible “crack” or “creak”. A great example of this is the annoying sound of “tapping your thumb”. Once the bubbles appear, they take more time to accumulate, which is why you can’t break your knuckles regularly, and why many people hear the knuckles when they get out of bed or get up from the permanent residence.
Connective tissue is a strong, flexible tissue that connects, protects, and lubricates joints. There are three types: ligaments, tendons and cartilage. Damage or loss of connective tissue has a negative effect on joint function, and causes various types of pain. Some injuries may require surgery to heal; for example, a third degree knee injury to the anterior cruciate ligament, more commonly known as an “ACL tear,” is a common knee injury that professional athletes often suffer and requires medical attention. the surgery. Loss of connective tissue may also require surgery or replacement.
Sprain – Straining or twisting of ligaments. (Full definition: Ligamts are short pieces of hard and soft connective tissue that connect two bones, or cartilage, or hold joints together)

The world’s population is aging: the growing number of adults with many physical and health problems is a global social and economic problem. Among these problems, the loss of mobility in adults due to musculoskeletal disorders is very important because it has social, psychological and physical effects. The joint control of the human body and early detection of these diseases will be a strong and effective solution to this problem. The intelligent joint monitoring system can detect and record musculoskeletal related parameters. Such devices can be used for continuous monitoring of joint movements during the normal daily activities of adults and the healing process of joints (hip, knee or ankle) during the postoperative period. Effective monitoring systems can be developed by combining miniaturized, durable, cheap and flexible sensors with advanced communication technologies and data processing techniques. In this study, we proposed and compared recently reported joint control methods and hearing technology. A discussion of data processing, interpretation, and analysis techniques is also presented. Finally, a focus on current research, as well as future and development challenges in unified control systems.

How Many Bones Are In The Human Body?
The human body is a highly developed mechanical system. The skeleton of the human body consists of 206 bones of different shapes, which are like the structure of the body, and the joints are the places where the bones meet. Joints hold the bones in place and provide stability and mobility to the bones [1]. As we age, our joints begin to wear down due to wear and tear
