The tubercle of a
ribis an eminence on the posterior surface, at the junction of the neck and body of the rib, and nearer the lower than the upper border.
It consists of an articular and a non-articular portion.
* The "articular portion", the lower and more medial of the two, presents a small, oval surface for articulation with the end of the
transverse processof the lower of the two vertebraeto which the head is connected.
* The "non-articular portion" is a rough elevation, and affords attachment to the ligament of the tubercle. The tubercle is much more prominent in the upper than in the lower ribs.
