Question

In which of the following connective tissues, the cells secrete fibres of collagen or elastin?
A. Cartilage
B. Done
C. Adipose tissue
D. Blood;E. Areolar tissue
Choose the most appropriate answer from the options given below :

• A. D, C, D and E only
• B. A, D, C and E only
• C. B, C and D only
• D. A, C and D only

Answer 1

The Correct Option is B

Fibroblasts are the principal cells that synthesize collagen and elastin fibers within connective tissues.
Cartilage, Bone, Adipose tissue, and Areolar tissue: These tissues house fibroblasts or analogous cells (chondrocytes in cartilage, osteoblasts in bone, adipocytes in adipose tissue) responsible for producing collagen or elastin fibers.
Blood: Fibroblasts are absent in blood. While its matrix (plasma) includes diverse proteins, these are not secreted by blood cells in a manner comparable to fibroblast secretion of collagen and elastin.
