Fixed joints are formed by the skull bones.
the joints which allow abduction of the shoulder are the glenohumeral joint which is formed between the humerus and the glenoid fossa, the sternoclavicular joint which is formed between the upper portion of the sternum and the clavicle and also the acromioclavicular joint which is formed between the acromion process and the clavicle all of these joints work together with the muscles which produce shoulder abduction to create this movement.
The joints between the vertebrae of the backbone are called intervertebral joints. These joints are formed by the articulation of the vertebral bodies and the intervertebral discs, which help provide stability, flexibility, and cushioning to the spine.
Although there are many joints in the skull, most are fused or immovable. The only bone that is free moving is the mandible, the lower jaw. The joints that connect the tooth to the socket are gomphosis joints, which allow little to no movement.
The shoulder is a joint; there is just one joint per shoulder.
Do you mean "How are stalactites formed?" ? They are deposits of calcite precipitated from solution in water dripping from joints in cave roofs.
Long bones typically have large joints such as the knee or hip joint. These joints are formed at the meeting point of long bones, like the femur or tibia, and provide stability and support for movement. The large size of these joints allows for a wide range of motion and weight-bearing capacity.
Traditional casement frames typically use mortise and tenon joints. These joints are formed by inserting a tenon (protruding piece) from one piece of wood into a mortise (groove) on another piece of wood, creating a strong and durable connection.
No. Your knuckles crack because of gas bubbles formed in the joints under pressure.
The type of joint formed from cartilage covering the articular surfaces of bones is called a synovial joint. In these joints, the cartilage provides a smooth, lubricated surface for articulation, allowing for a wide range of motion. Synovial joints also have a synovial membrane that produces synovial fluid, further facilitating movement and reducing friction. Examples include the knee, elbow, and shoulder joints.
Bones are held together by joints, which are formed by connective tissues such as ligaments and cartilage. Ligaments connect bone to bone and provide stability, while cartilage helps cushion the joints and reduce friction during movement.
Rheumatic fever does not affect throat. It does affect heart and joint. This happens probably because the antibodies formed against the beta haemolytic streptococci also attack the heart valves and the joints. Probably they have similarity with the antigen of bacteria.
