Question

Chondroblasts ________.

A) are mature cartilage cells located in spaces called lacunae
B) within the cartilage, divide and secrete new matrix
C) located deep to the perichondrium divide and secrete new matrix on the internal portions of the cartilage
D) never lose their ability to divide

Answer 1

Chondroblasts are cells in cartilage that divide and secrete new matrix, eventually becoming mature chondrocytes in lacunae. They contribute to cartilage formation and growth but lose their ability to divide as they mature.

Step-by-step explanation:

The question concerns the biological function of chondroblasts in cartilage. Chondroblasts are cells that divide and secrete new matrix within the cartilage, contributing to its growth and maintenance. They are responsible for producing and maintaining the cartilaginous matrix and eventually differentiate into chondrocytes, which are mature cartilage cells located in spaces called lacunae. Over time, chondrocytes can lose their ability to divide, particularly when they get entrapped in their own secreted matrix as it calcifies during endochondral ossification.
