But just like humans, they have special fibres called “nerves”, which run like tiny wires all through their body, and some of them end near the surface of the skin. These nerves are what can make a chicken keep moving, even after its head has been chopped off.

Mike survived because most of a chicken’s brain is located in the back of its head, behind the eyes. When Olsen brought down the axe, he lobbed off most of Mike’s head but left the part of the brain that controlled breathing, digestion, and other bodily functions.

No, they don’t feel pain during this time because they are already dead, and the pain would be felt from the brain, which processes the impulses sent by the nerves; the brain is no longer connected to the body, so there is nothing left to process what is happening.

Typically, an animal’s head contains its brain. The nervous system is essential to body movement — without it, animals with brains could not move. Therefore, when a chicken’s head is cut off but the spinal cord and nervous system is left intact, the chicken can move around.

For a human to lose his or her head would involve an almost total loss of the brain. For a chicken, it’s rather different. “You’d be amazed how little brain there is in the front of the head of a chicken,” says Smulders. It is mostly concentrated at the back of the skull, behind the eyes, he explains.

Part of the reason that a chicken can live without its head has to do with its skeletal anatomy, according to Dr. Wayne J. If the bird still has a bottom beak, the cerebellum and brain stem are likely still intact, which makes the chicken’s basic motor functions and ability to breathe quite likely.

Although head transplantation by the reattachment of blood vessels has been successful with animals, a fully functional reattachment of a severed human head (including repair of the spinal cord, muscles, and other critically important tissues) has not yet been achieved.

Sometimes a section of a nerve is cut completely or damaged beyond repair. Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves to regrow.

If an accident or trauma results in complete amputation (the body part is totally severed), the part sometimes can be reattached, often when proper care is taken of the severed part and stump, or residual limb. In a partial amputation, some soft-tissue connection remains.

Limb replantation is a complex microsurgical procedure that allows patients to have severed limbs reattached or “replanted” to their body. Most patients need limb replantation within hours of experiencing traumatic injuries. Depending on the type of injury you have, surgical specialists can replant some severed limbs.

Replantation is the surgical reattachment of a finger, hand or arm that has been completely cut from a person’s body (Figure 1). The goal of this surgery is to give the patient back as much use of the injured area as possible. This procedure is recommended if the replanted part is expected to function without pain.

Small injuries may often heal on their own. If the injury is long or deep, it may need stitches that dissolve over time. If a piece of your tongue was cut off or bitten off, it may have been reattached. Follow-up care is a key part of your treatment and safety.

But back in the 1970s, scientists showed that children can sometimes regrow the tip of an amputated finger, as long as there’s a bit of nail left over and the wound isn’t stitched up.

The little finger is nearly impossible for most people to bend independently (without also bending the ring finger), due to the nerves for each finger being intertwined.

The liver is the only organ in the human body that can regenerate. Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.

If you have the cut-off tip, clean it with water. If you have a sterile saline solution, use that to wash it. Wrap it with moistened gauze or cloth….Use saline solution if you have it.

1. Don’t put alcohol on your finger or toe.
2. Use a clean cloth or sterile bandage to put firm pressure on the wound to help stop bleeding.

You’ll likely need stitches if the wound: Bleeds enough to soak through a bandage. Keeps bleeding even after you apply direct pressure for 5 to 10 minutes. Spurts blood….What caused it?

1. Animal or human bite.
2. Dirty or rusty object.
3. Pointed object that might have driven deep into the skin, such as a nail.

This type of wound will form new skin only on the edges of the wound and heals from the edges into the middle. The larger the wound, the longer it will take to heal, and the greater the risk of infection. Cutting off the tip of a finger or toe are common avulsion injuries.

The body’s largest organ might seem barely more than cellular wrapping paper, but skin has roles that range from fending off microorganisms to regulating body temperature. It also has a considerable flaw: severely damaged skin can heal, but it can’t regenerate.

Complete healing usually takes from 2 to 4 weeks, although stiffness and hypersensitivity may remain longer, depending on the severity of the injury. Larger tissue injury. If your fingertip wound is large and open, there may not be enough remaining skin to heal and cover the open area.

A cut finger injury is a medical emergency if: The cut reveals deep layers of skin, subcutaneous fat, or bone. The edges of the cut can’t be gently squeezed together because of swelling or the size of the wound. The cut is across a joint, having possibly injured ligaments, tendons, or nerves.

A wound that is not stitched may take 1 to 4 weeks to heal, depending on the size of the opening. You will probably have a visible scar. You can discuss revision of the scar with your healthcare provider at a later time.

To treat a minor cut, dermatologists recommend the following tips:

1. Wash your hands with soap and water.
2. Wash the cut to prevent infection.
3. Stop the bleeding.
4. Apply petroleum jelly.
5. Cover the cut with a sterile bandage.
6. Consider taking over-the-counter pain medication.

To help the injured skin heal, use petroleum jelly to keep the wound moist. Petroleum jelly prevents the wound from drying out and forming a scab; wounds with scabs take longer to heal. This will also help prevent a scar from getting too large, deep or itchy.

Once the wound is clean, there are several techniques to speed up the healing process. These include the use of antibacterial ointments, turmeric, aloe vera, garlic, and coconut oil. A person should seek medical help right away if their wound is large.

Petroleum jelly is best used to halt the bleeding from shallow cuts. Wipe the skin dry beforehand and clean the wound to remove any remaining jelly after the bleeding has stopped. A range of petroleum jelly products is available for purchase online.
