Answer:
Typically, the ribs have the following anatomical components:
Head with two articular facets
Tubercle
Neck
Shaft
Costal groove
Most of the ribs are typical ribs ie they have all these features. The atypical ribs which do not have all these features are:
First rib (wide and short, has two costal grooves, and one articular facet)
Second rib (thin, long, and has a tuberosity on its superior surface for the attachment of the serratus anterior muscle)
Tenth rib (only one articular facet)
Eleventh rib, Twelfth rib (one articular facet with no neck)
The functions of the ribs are critical, as they
protect the contents of the thoracic cavity and mediastinum
move superiorly, inferiorly, anteriorly and posteriorly to facilitate breathing (their flexibility in their movement increases/decreases the size of the thoracic cavity; assisting the lungs in respiration. Control of these movements is via the diaphragm, external intercostals, and the intercartilaginous portion of the internal intercostals).
provide a place where some muscles originate or attach
play a role in erythropoiesis during development (at birth, the erythropoiesis sites change, it recedes in long bones and persists in flat bones, like ribs)[2]
