There is not one "joint" in the neck. It is a series of complicated joints that have a place for the spinal cord to go through and the bones of the spine protect the spinal cord. The cervical spine has more than just one ROM and that could not be accomplished with a shoulder joint.
Yes. Unless it is the shoulder joint in question, as you can imagine it would be hard to grip with one hand.
The joint would eventually break possibly with disasterous results for your own safety get it replaced as soon as possible.
If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
Imagine a shoulder that acted like you knee. It could only extend in one direction.
If it is only the joint, you would find an orthopedic doctor who specializes in shoulders.
that would be the shoulder
They would grind together.
The three functional articulations are synarthrosis which is an immovable join and example would be a suture, amphiarthrosis a slightly immovable joint an example is the symphysis, and last the diarthrosis a freely movable joint such as the elbow or knee joint.
nothing would happen
you will need a cast
It would seem that it would be called that but when dealing with the arms and legs, the positional anatomy only involves the attachment to the body. We use proximal and distal and not inferior and superior. The point of attachment (POT) is the shoulder joint. Since the elbow is further away from the POT, is said to be distal. And the shoulder joint is proximal to the elbow. You must always use two things to compare. In this case the elbow and the shoulder.
In the shoulder and also your hip is a ball joint. A ball joint is the most mobile joints of the human body. A ball joint allows you to use your legs and arms in a lot of different directions.
