Detailed Solution

In humans, most of the ribs are provided with two articulations and both are articulated with thoracic vertebrae.

True Ribs (Vertebrosternal Ribs): The first seven pairs of ribs are considered true ribs because they directly connect to the sternum through their own costal cartilage.
False Ribs (Vertebrochondral Ribs): The next three pairs of ribs (8th, 9th, and 10th ribs) are referred to as false ribs. They do not directly attach to the sternum but instead join the cartilage of the rib above them.
Floating Ribs (Vertebral Ribs): The last two pairs of ribs (11th and 12th ribs) are floating ribs. They do not connect to the sternum or the rib above, and their free ends are located in the posterior part of the body.
