Ball and socket joint

Where two bones meet or link, it is called a joint or an articulation. Joints can be classified according to their structure and by the types of movement they allow. The body has more than 300 different joints. In the body there are three types of joints... Moveable/Synovial joints – Moveable joints allow for maximum movement. Moveable or synovial joints are normally found in the limbs, as we use these parts more than anything. Ligaments help to provide the stability of the bones, also the muscles

Pivot joints (known also as rotary joints). These joints allow for rotation around an axis. There is a pivot joint near the top of your spine that allows your head to move from side to side. Hinge joints. This type of joint can open and close like a door. Your elbow is a hinge joint. Your biceps and triceps muscles are basically two people standing on opposite sides of a wall (the humerus, or upper-arm bone), each with one hand reaching over to its respective side of a door (the bones of the lower

known as CHD, is a severe condition in which as dogs begin to grow and mature their ball and socket joints are not properly aligned, resulting in instability or laxity of the hip joint. The malformation of the ball and socket joint cause a very painful sensation developed by the joints rubbing and grinding together, instead of the normal comfortable smooth sliding of the hip joint. Due to the laxity of the hip joint overtime the cartilage, making it a comfortable movement begins to wear down. Once

of the way off of the bone. This type of tear usually correlates with an injury to the shoulder where the shoulder has subluxated or dislocated. Sometimes, this tear occurs and the individual does not realize that the shoulder has slid out of the socket. This can make it much worse and cause other types of injuries to the ligaments around the shoulder. The second type of labrum tear is tearing within the actual labrum. The sides of the labrum after a while may get frayed, meaning a slight tear where

1 . Describe the Major bones, muscles,joints and joint actions used to perform this movement skill and how they influence the way the body moves. The overarm throw is a skill frequently used in a wide range of sports such as cricket,softball and baseball. The action is also used in athletic activities such as javelin, with the overhead serve and smash in tennis, volleyball and badminton and passing a netball and basketball.An overarm throw is the action of the arm swinging backwards then upwards

head, shoulders and hips vertically aligned. A dancer with good technique requires good placement, alignment and turnout. Turnout refers to completing movements with your legs rotated outwards using the six deep outward rotators of the hip joint (ball and socket). This promotes clean footwork, graceful port

relation to the importance of correct moving and positioning of individuals Body joints are where two bones meet. Joints help enable our bodies to move. Types of joints * Ball and socket joints: are the most mobile type of joint in body * Joints between the vertebrae in spine: are connected to each other by pads of cartilage. These joints can only move a small amount. * Synovial joints: are movable joints containing synovial; a lubricating

shoulder joint and in- between the pelvis and the femur (Shoulder: Torn Labrum, Palo Alto Medical Foundation). The labrum has two basic functions that take place in both the hip and the shoulder. The first function of the labrum is to excavate the socket so that the ball stays secure. Ligaments are small structures that keep the ball in the socket; these are the harnesses that reach and attach each of the bones. These small structures hold the bones closer together. The other way the ball is kept

The Glenohumeral Joint and its Function Within the Human Body The glenohumeral joint, or shoulder joint, is one of the human body’s appendicular joints and boasts the greatest ROM (range of motion) of any joint in the body. An appendicular joint is a joint that is part of the appendicular skeleton which includes the pectoral girdle, pelvic girdle, and limb bones. The appendicular joints typically have a larger range of motion, but due to this are often weaker than those found in the axial skeleton
