If a piece of flesh is cut off from the palm of the hand, will it grow back? 20

There will definitely be scars, so take good care of them to avoid hand friction injuries.

If the palm of the hand is cut off, a piece of flesh can grow back.

First, the blood vessels around the two-centimeter wound around the heart of the palm of the hand below the thumb will constrict, thereby reducing bleeding from the wound, and the damaged blood vessels will release red blood cells and platelets that collect at the wound in the palm, creating emboli or clots. The inflammatory phase will dilate the capillaries, increase the permeability of the capillaries, let the serum and white blood cells gather in the wound area, and the white blood cells will differentiate into different neutrophils and macrophages, attracted by the wound damaged cells and chemicals on the bacteria, and become phagocytic cells to engulf bad tissues and bacteria, until all the necrotic tissue of the wound is eliminated, and the inflammation will slowly disappear.

After the wound inflammation phase, the cell proliferation phase begins, which is the formation of mother cells and fresh granulation tissue, which gradually heals from the bottom of the severed flesh in the palm of your hand and fills the wound.

During the scar phase, fibroblasts and granulation tissue will gradually form scar tissue, and the tension of the scar tissue will prevent the wound from dehiscing until the wound is completely healed.

If the palm flesh grows back does not mean that the hand has recovered as before, if the hand nerve or tendon is injured during the injury, the extent to which the hand can recover depends on the healing situation.

Hello, it shouldn't be, even if it's good, there will be a deep imprint.

Fingers cut off a piece of meat. If the excised tissue is a relatively small part of the epidermis, it can be repaired after 10 days to half a month. If more tissue is removed, the repair time may be longer.

If part of the muscle tissue is removed, then a complete recovery is less likely.

For example, if the cut flesh or nails are also cut off at the same time, then no matter how long it is, it will not grow, because there is no blood in this place**, but this place can be healed slowly, and the granulation tissue will slowly grow in the place where it is cut, and it will slowly cover from the periphery to the middle, and it will eventually heal. If the nail bed is cut off, the cut part will not grow new nails, if this happens, the defect is relatively large, skin grafting, and then dressing**.

The extent and extent of the finger injury must be considered, and if only the epidermis is removed, the nail mechanism is not involved. In the later stage, with healing, the correct dressing change operation can be gradually restored.

If the depth of the cut is large, such as the dermis and nail mechanism are damaged, the scar is difficult to heal and difficult to recover on its own. However, in any case, it is necessary to change the dressing correctly as soon as possible after the injury, and at the same time, debridement and suturing can be carried out for larger wounds to promote the recovery of the wound quickly.
