In the adult human body, there are:

*24 Ribs*

divided into:

1. *True Ribs* (12 pairs): Directly attached to the sternum (breastbone)
2. *False Ribs* (6 pairs): Attached to the 7th thoracic vertebra, not directly to the sternum
3. *Floating Ribs* (6 pairs): Short, not attached to any vertebra or the sternum

Ribs are classified into three categories based on their attachment:

1. True Ribs (1-7): Articulate with the sternum
2. False Ribs (8-12): Connect to the 7th thoracic vertebra
3. Floating Ribs (11-12): Do not articulate with any vertebra or the sternum

*Interesting fact:* Humans have 24 ribs, but some individuals may have an extra rib, known as a cervical rib, located above the normal 24 ribs.

*Function:* Ribs provide:

1. Protection for internal organs (heart, lungs, etc.)
2. Support for the thoracic cavity
3. Attachment points for muscles
