The ribs articulate with the (a) thoracic vertebrae.
There exists 12 pairs of ribs. Each rib is a thin flat bone attached dorsally to the vertebral column as well as ventrally to the sternum.
First seven pairs of ribs are known as 'true ribs'. They articulate with the thoracic vertebrae dorsally and are ventrally attached to the sternum by means of of hyaline cartilage.
The 8th, 9th as well as 10th pairs of ribs do not articulate directly with the sternum but unite with the 7th rib with the support of hyaline cartilage. These are called 'false ribs'.
Remaining two pairs i.e. the 11th and 12th pairs of ribs are not attached ventrally and are thus, termed as 'floating ribs'.

A kind of behavior by a person's action is called positive sanction and punishments in an action considered as negative sanction.
<u>Explanation:
</u>
The difference between positive sanction and negative sanction is as follows.
Positive sanction:
- An action that results in a 'particular kind of behavior' is known to be a positive sanction.
Negative sanction:
- An action of punishment or threat of 'punishment is used as a means to enforce conformity' is known to be a negative sanction.
The common point:
- Neither positive nor negative sanction works if people by themselves are not sure whether they should be rewarded or punished for a particular behavior. So, there is no common line between Negative and Positive sanction.
