C. In the isogenic chondrocyte groups

D. Adjacent to the collagen fibers of the matrix

E. Outside of the perichondrium

5. What serves as a skeletal model for most bones?

A. Elastic cartilage

B. Perichondrium

C. Epiphyseal plate

D. Hyaline cartilage

E. Glycosaminoglycans

ANSWERS

1. Correct Answer: A. Proteoglycan aggregates. Water molecules are

attracted to the negatively charged sulfate ions in the proteoglycan
aggregates.

2. Correct Answer: E. Their reflective index is similar to that of the ground
substance of hyaline cartilage.

3. Correct Answer: C. Chondrocytes. After synthesizing the matrix,
chondroblasts become surrounded by cartilage matrix, stop dividing, and
become chondrocytes.

4. Correct Answer: B. On the inner layer of the perichondrium. This layer
contains mesenchymal cells that differentiate into chondrogenic cells,

chondroblasts, that produce the cartilage matrix.

5. Correct Answer: D. Hyaline cartilage. This cartilage produces a bone
model for most bones of the body. The hyaline cartilage in most bones
eventually calcifies and transforms into a bony structure.
