Ball and socket.
ball and socket
your hip (coxal) joint. a ball and socket joint is one where all types of movement are possble (eg. flexion, extension, abduction, adduction, circumduction ) you can do this at your hip. another ball and socet joint is your shoulder
Hip joint is rotation joint. You can not imagine playing foot ball without the use of this joint.
The femur is almost verticle and strong bone. It can bear the lot of weight. It is slightly convex anteriorly. That gives you added advantage in weight bearing. Convexity on anterior side, enable you to to tolerate the trauma from the front side in better way. There is an angle between the head neck portion and shaft of the femur. That shift the location of the femur away from the hip bone. This arrangement shifts the line of weight transmission towards side way. Then you have the ball and socket type of joint at the hip joint. That allows all types of movement across the joint. You have the knee joint to give you hinge joint. This allows for bending the knee more or less. Together with these features the femur is architectural marvel.
No, the knee is not an example of this. The knee is an example of a hinge joint along with your elbow. The hip and shoulder joints are examples of a ball and socket joint as it has movement in all directions. Your knee can only move up and down like the hinge on a door. Hence that is why it is called a hinge joint!
Firs of all arthritis or trauma to the hip joint followed by reduction in use followed by atrophy to the surrounding muscles
the hip and shoulder are examples of a ball-and-socket joint.
Your elbow is a hinge joint in your body, as is your knee.
§The hinge joint: permits a motion, allowing parts of the body to extend and flex. With this particular joint, one bone must be concave and the other convex to allow the most extensive range of motion. An example of a hinged joint used in swimming would be the knee.
