Question

White fibrous tissue is
A. Nerve
B. Muscle
C. Ligaments
D. Tendons

Answer 1

Hint: Connective tissues have the ability to stretch and contract positively. They support and protect the internal structure of the body.

Complete answer:
Tendons are the white fibrous tissues. They are the dense regular connective tissue that appears silvery. They are physically tough but pliable in nature. The fibres of these tissues may be regularly or irregularly arranged. It consists of fibroblasts that scattered among many collagen fibres and are often aligned in the same direction. White fibrous tissues arise in two forms: tendons and sheath.
Tendons: They are the thick bundle of collagen fibres that run parallel to each other. Due to the presence of collagen fibres, they are strong, flexible but inextensible. Tendon joins skeletal muscles to bones.
Sheath: Sheath is the bundles of collagen fibres that lie in a criss-cross shape. They are generally present in the pericardium of heart, sclera of the eye, a capsule of the kidney, spinal cord, etc. It covers the cartilage and bones.

Additional information:
- White fibrous tissues contain fibroblast cells, collagen fibres and very less amount of matrix.
- They range in the size from less than 1 µM to about 12 µM.
- The dense network of collagen fibres gives it mechanical strength and makes it tough.
- These tissues protect the internal organs of the body.
- They possess high tensile strength.
- These tissues have a very poor blood supply, which is why the healing of injured tendons or ligaments is very slow.

So, the correct answer is ‘Tendons’.

Note:
> Ligaments are composed of yellow elastic fibrous tissues and some collagen fibres. It joins bones to other bones.
> Ligaments support the internal organs and hold bones together in suitable articulation at the joint.
