Question

Ligaments are made up of
A. White fibres and some yellow elastic fibres
B. White fibres only
C. Yellow fibres only
D. Yellow fibres and muscle fibres

Answer 1

Hint: Ligaments are present in the skeleton of the body. It is found connecting most of the bones inside the body and it also supplies limits to the number of movement between the bones.

Complete answer:
Ligaments are the fibrous connective tissue that joins the bones and makes joint movement easier. It generally refers to the line of dense regular connective tissue bundles which are made from collagenous fibers, with bundles shield by irregular connective tissue sheaths. Ligaments are of two major types i.e. White ligament and Yellow ligament. White ligaments are rich in collagenous fibers, which are elastic and muscular. Yellow ligaments are rich in elastic fibers which are quite tough although they permit elastic movement.
These ligaments are specialized connective tissues with biomechanical properties. The fundamental building block of the ligaments is collagen fibers, they are very strong, flexible, and also immune to damage from compressing stresses. These fibers are aware of local and systemic factors that influence their functions. Any injury to the ligament leads to serious changes in its structure and physiology and creates a situation where ligament function is restored by the formation of connective tissue which is biologically and biomechanically inferior to the tissues it replaces.

So, as we have discussed the correct answer is A (White fibres and some yellow elastic fibres).

Note:
Ligaments basically connect one bone with another bone to make a joint whereas tendons connect bone with muscle. There are some ligaments which restrict the mobility of the junction or prevent certain movements.
