Question

Which of these statements are true when considering the formation of a scar?


  1. A scar is always formed when a wound closes.

  2. Scars are formed due to the malfunctioning of WBCs.

  3. When connective tissues heal the wound, the scar remains.

  4. Scars are formed due to low platelet count when healing.


Solution

The correct option is C

When connective tissues heal the wound, the scar remains.


Healing of the wound is a stage that comes after inflammatory response and blood clotting. When a wound occurs, new tissues are formed in place of the tissues damaged by the wound. In such situations, the wound scar does not remain. But, in cases where new tissues cannot be formed, the connective tissue heals the wound. In such situations, the wound scar remains as the fibres formed here are different from fibres formed by normal tissues.
