The jugular notch is the thickest part of the bone and is convex along anterior and concave along the posterior side. 7 The body of the sternum is longer and thinner. It has margins that articulates with the seven first cartilages of the ribs. 2,7 The xiphoid process is the lowest part of the sternum and also the smallest part. It doesnât articulate with the ribs.
