I dont think, I KNOW! the cells that make up the human body continually divide by a process called mitosis. eventually, enough cells will have divided to fill up the hole in the skin. if you want to learn about mitosis, please visit http://en.wikipedia.org/wiki/Mitosis
injuries to the skin heal faster than injuries in the brain because of cell division. When your skin cuts it heals faster then when something happens to your brain because your skin cells wear out quickly, so they need to be replaced often. That's why it is faster to heal than injuries to the brain :)
Injuries in the brain do not heal because brain cells cannot grow back. On the other hand body cells (skin) do grow back.
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
it depends upon how deep the wound is and area, skin conditions, and type of injury
What is considered a scar would be an injury that leaves a mark. Scars are injuries to a persons skin that have not healed yet or will not ever heal.
after a couple of days it should scab over then after another week or so it should heal completely
Skin injuries typically heal using regeneration in which the dead or damaged cells are replaced by identical cells, while more severe injuries may heal using fibrosis. Fibrosis will not restore the function of the lost cells, however, the scar tissue is capable of holding the organ together. Therefore, regeneration is more desirable.
yes it will it will take some day but it will heal
Aging skin doesn't heal as well due to a decrease in collagen production, reduced skin elasticity, and slower cell turnover rates. These factors can impair the skin's ability to repair and regenerate itself effectively, leading to delayed wound healing and a higher susceptibility to skin damage.
You can use a type of lotion which would help it heal and make it soft and healthy.
Collagen, but I don t think you can find it sold...
One way skin injuries heal is by blocking an opening with platelets from the blood. When you get cut, a bunch of platelets rush to the area and start forming a clot with fibrin. This is what a scab is. Also the scab is just a quick fix the real repairs begin after the scab is formed and the repairs occur under the scab.when the repairs are completed the scab starts to fall off.
