Collateral
In anatomy, a collateral is a subordinate or accessory part. A collateral is also a side branch, as of a blood vessel or nerve. After a coronary artery occlusion, collaterals (that is, collateral vessels) often develop to shunt blood around the blockage. The word "collateral" comes from the Latin "col-", with + "latus", side = with the side, situated at the side. (The prefix "col-" is a variant form of "com-" meaning "with" that is used before an "l".) Hence, collateral means accessory, subordinate, secondary, serving to support or reinforce. In the sense of being on the side and in the sense of serving to support or reinforce, there are collateral ligaments outside of the knee joint. The collateral ligaments help provide stability and strength to the knee joint
