When it comes to chewing gum, it's the type of gum you chew that makes a difference in whether it's helpful or harmful to your teeth. While chewing gum containing sugar may actually increase your chances of developing a cavity, there is clinical evidence that demonstrates just the opposite for sugar-free gum.
The olecranon process is the prominent bony projection of the ulna bone that can be felt at the elbow. Hook-like in shape, it is the structure that curves around the bottom of the humerus bone in the upper arm and encapsulates the elbow joint. It also is the site of attachment for several muscles of the arm.
Structure [edit]. It is situated at the upper (proximal) end of the ulna, one of the two bones in the forearm. When the hand faces forward (supination) the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus in extension of the forearm. Its base is contracted where it joins the body and the narrowest part of the upper end of the ulna.
