The Joint

The Julie is perfect. She is very smart and popular. Her natural blonde is a professional style at least once a week and her figure 8 is always wearing designer brand gloves. She is involved in school teams and clubs including gymnastics and dance, politics of all social clubs and schools. Jen is far from that. She is called "bad". She dyed her black hair as she was unable to see her half face and she was always wearing uniform black.

Synovial joint: Through the cartilage combined with the synovial membrane enclosed in the joint space. These are the most common joints that provide freely moving joints between bones to be joined. They are the most typical function of limb joints. Synovial joints are named after the synovial fluid they contain. This lubricant allows the dancer's joints to move freely and smoothly. Joint axis: Joints can move in one direction (single axis) or multiple directions. Hinged joints such as elbows and knees are biaxial joints and allow movement in two directions: bending or stretching only. Ball joints such as waist and shoulder are multiaxial joints because they can move in multiple directions.

Joint structure / joint type: Flexibility is specific to each joint and joint design. The joint of the ball and socket (3 axes) is easier to move than the grillgrins joint (1 axis). Connectors are categorized into four categories: no motion (non-axial direction), uniaxial, biaxial, or triaxial. Therefore, in the joint ROM, the structure of the joint is the main determinant. Muscle mass / body formation: The role of muscle mass in flexibility is important, but it is often emphasized often. Generally, the upper body thickening muscles such as chest and arms may restrict movement. However, even if the muscle spreads throughout the muscle ROM, it is usually flexible. Male gymnasts are good example of hypertrophy and high elasticity. Thus, muscle mass can play a role in reducing flexibility, but it is possible to minimize adverse effects by securing complete ROM during muscle contraction.
