Although this constriction is called the centromere, it usually is not located exactly in the center of the chromosome and, in some cases, is located almost at the chromosome's end. The regions on either side of the centromere are referred to as the chromosome's arms. WebThese are usually divided into a "short arm" and a "long arm" of the chromosome. The short arm, which is the upper half of the chromosome, is known as the "p arm." The long arm, which is the lower half of the chromosome, is the "q arm."
