MICROANATOMY

Detailed explanation-1: -There are two major types of ligaments-the white ligament is rich in collagenous fibers, which are sturdy and inelastic, and yellow ligament which is rich in elastic fibers, which are quite tough albeit they permit elastic movement.

Detailed explanation-2: -Collagen fibres are white in colour and are made up of collagen protein. The fibres are unbranched and usually occur in bundles. Elastic fibres are yellow in colour and are made up of elastin protein. The fibres occur singly and are branched.

Detailed explanation-3: -The correct option is D elastin. Elastic cartilage is referred to as yellow fibrocartilage. The protein found in yellow fibres is elastin which is found in the extracellular matrix of the connective tissue.

Detailed explanation-4: -Elastic fibres, consisting of the protein elastin, are yellow in colour and much thinner and less wavy than collagen fibres.

Detailed explanation-5: -The yellow fibres are thicker and fewer than white fibres. They are straight and occur singly. They are flexible, elastic and branched. White fibres on the other hand occur in bundles, called as fascia and are formed of collagen.
