Relation between cleavage lines and scar tissues

As viewed in relation to cleavage lines, the histological structure of scar tissues, whether old or new, closely simulates the structure of a cable. Bundles of collagen fibres, the main component of scar tissue, that run at right angles to the direction of the cleavage lines, may be likened to a cable core while fibres that surround the main structure of the scar tissue, parallel with the direction of the cleavage lines, may be likened to the coating material of a cable.
