  • Assertion: Dense regular connective tissue has a regular arrangement of collagen fibers, while dense irregular connective tissue has an irregular arrangement of collagen

Assertion: Dense regular connective tissue has a regular arrangement of collagen fibers, while dense irregular connective tissue has an irregular arrangement of collagen fibers.

Reason: The arrangement of collagen fibers in dense connective tissues affects their strength and resistance to tension.

Option: 1

Assertion and reason are both true, and reason is an accurate account of assertion. 


Option: 2

Both assertion and reason are accurate, but reason does not adequately explain assertion.


Option: 3

The assertion is correct, but the reasoning is incorrect. 

 


Option: 4

Both the claim and the justification are true. The body contains two different types of connective tissue: dense regular connective tissue and dense irregular connective tissue.

Collagen fibres that are closely packed and organised in parallel makeup dense regular connective tissue. Due to this configuration, the tissue has high tensile strength in the fibre orientation direction. Tendons and ligaments, which connect muscles to bones and bones to one another, respectively, include dense regular connective tissue.

Collagen fibres are arranged irregularly in thick, asymmetric connective tissue. The dermis of the skin and the capsules of organs are two examples of tissues where tension is applied in many directions. Collagen fibres are arranged erratically in dense, amorphous connective tissue, increasing its resistance to stress and tension in various directions.

The justification given in the statement is also true. Collagen fibre organisation in dense connective tissues is critical to how well they perform. Collagen fibres are arranged irregularly in dense irregular connective tissue, whereas collagen fibres are arranged parallel in dense regular connective tissue, allowing it to resist force in more than one direction.

Option 1 is the correct answer.
