Regeneration in humans Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, which involves closing up the injury site with a scar. Some tissues such as skin and large organs including the liver regrow quite readily, while others have been thought to have little or no capacity for regeneration. However ongoing research, particularly in the heart and lungs, suggests that there is hope for a variety of tissues and organs to eventually become regeneration-capable. In humans with non-injured tissues, the tissue is naturally regenerated over time; by
Body part as an object - the motor and visual cortices - involved in using or viewing objects and events, and thus facilitates the production of a representational gesture. Therefore, when objects are thought of using mental or visual imagery, more gestures should be produced. On the other hand, if an object is thought of only through its verbal representation, there should be fewer gestures present. Tool-use is the manipulation, or use, of an object using the hands. It is one of the many skills that separate humans from animals. There are two factors used to explain tool-use in humans. First of all, part of
