🦴 True Ribs – Basic Anatomy Concept

In human anatomy, ribs are classified into three groups based on how they attach to the sternum (breastbone). These are true ribs, false ribs, and floating ribs.

What are True Ribs?
True ribs are the ribs that attach directly to the sternum through their own costal cartilage.

In the human body, there are 7 pairs of true ribs. They extend from the first rib to the seventh rib and connect directly to the sternum.

Explanation:
The rib classification is as follows:

• True ribs: 1st to 7th ribs (directly attached to sternum)
• False ribs: 8th to 10th ribs (attached indirectly through cartilage)
• Floating ribs: 11th and 12th ribs (no attachment to sternum)

Therefore, when we talk about true ribs in terms of numbering, they include ribs from 1 to 7.

Exam Point:
True ribs = 1–7
False ribs = 8–10
Floating ribs = 11–12
