Question

Quizplus · Accepted Answer

Appositional growth is the secretion of new matrix against the external face of existing cartilage, which results in the increase in the width or girth of the tissue. It occurs in mature cartilage where chondroblasts in the perichondrium secrete new cartilage matrix against the external face of the existing cartilage tissue.
