Question

When chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within. This process is called __________. a) appositional growth b) calcification c) hematopoiesis d) interstitial growth.

Answer 1

The correct option is d). The process is called interstitial growth.

Step-by-step explanation:

The cartilage is composed of chondrocytes, which are located in small spaces called lacunae. Its function is to synthesize the extracellular matrix of cartilage. Its growth occurs through two processes: appositional growth and interstitial growth. When chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within, the process is known as interstitial growth, this happens because the young chondrocytes divide mitotically, forming a group called isogenous, while forming the matrix, each one separates, creating its own lacunae. As a result of the increase of chondrocytes and the secretion of the new intercellular matrix, it causes the cartilage to grow (expand) from within.
