APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The ribs perform vital functions in the body, protecting organs and supporting the breathing process. The vast majority of human beings are born with 24 ribs, 12 on each side of the body.

Detailed explanation-2: -How many ribs do humans have? The vast majority of people are born with 12 pairs of ribs, for a total of 24, no matter their sex. The exception to this anatomy rule are people born with specific genetic anomalies. These can take the form of too many ribs (supernumerary ribs) or too few (agenesis of ribs).

Detailed explanation-3: -Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.

Detailed explanation-4: -In humans there are normally 12 pairs of ribs. The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8th, 9th, and 10th pairs-false ribs-do not join the sternum directly but are connected to the 7th rib by cartilage.

Detailed explanation-5: -There are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint. An exception to this rule is that the first rib articulates with the first thoracic vertebra only.
