The neck of the rib is the flattened portion which extends laterally from the head; it is about 2.5 cm. long, and is placed in front of the transverse process of the lower of the two vertebræ with which the head articulates.
Its anterior surface is flat and smooth, its posterior rough for the attachment of the ligament of the neck, and perforated by numerous foramina.
Of its two borders the superior presents a rough crest (crista colli costœ) for the attachment of the anterior costotransverse ligament; its inferior border is rounded.
On the posterior surface at the junction of the neck and body, and nearer the lower than the upper border, is an eminence—the tubercle; it consists of an articular and a non-articular portion.
