Question

which of the following is/are characteristic of interstitial growth in cartilage? interstitial growth occurs within the cellular layer of the perichondrium. the cartilage expands from within as chondrocytes in the matrix divide, grow, and produce new matrix. the cartilage grows at the external surface through differentiation of fibroblasts into chondrocytes all responses are correct. i dont know yet

Explanation:

Interstitial growth in cartilage involves chondrocytes within the matrix dividing, growing, and producing new matrix, causing expansion from within. Perichondrium - related growth is appositional, and fibroblast differentiation for growth is also appositional. So the correct description is the second option.

Answer:

The cartilage expands from within as chondrocytes in the matrix divide, grow, and produce new matrix.
