Question

4 points
Dense connective tissue is called dense because
(1) Collagen fibres are oriented differently
(2) Adipocytes are less in number
(3) Fibres and fibroblasts are compactly packed
(4) The ground substance is semi-fluid.
Option 1

Answer 1

Answer:

It is because that fibres are more, cells are less and ground substance is very little so the relevant option may be 3)

Answer 2

Answer:

The correct answer is 3) Fibres and fibroblasts are compactly packed.

Explanation:

• Dense connective tissue forms the extra cellular matrix containing predominantly Type 1 collagen.
• There are rows of tightly packed fibroblasts which generate collagen fibres.
• Collagen is a protein molecule containing a Glycine-X-Y structure where X and Y are proline and lysine residues.
• Hydroxyproline, hydroxylysine, and glycosylated hydroxylysine residues provide strength to the collagen fibril.
• In dense connective tissues, the fibres and fibroblasts predominate over the cellular structures.
• They are present mostly in areas where strength, support and firmness is required.
