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.
There are some human organs and tissues that regenerate rather than simply scar, as a result of injury. These include the liver, fingertips, and endometrium. More information is now known regarding the passive replacement of tissues in the human body, as well as the mechanics of stem cells. Advances in research have enabled the induced regeneration of many more tissues and organs than previously thought possible. The aim for these techniques is to be used in the near future to regenerate any tissue in the human body.
Wrinkles are the lines and creases that form in your skin. Some wrinkles can become deep crevices or furrows and may be especially noticeable around your eyes, mouth and neck.
Wrinkles are caused by a combination of factors — some you can control, others you can't:
As you get older, your skin naturally becomes less elastic and more fragile. Decreased production of natural oils dries your skin and makes it appear more wrinkled.
Fat in the deeper layers of your skin diminishes. This causes loose, saggy skin and more-pronounced lines and crevices.
Ageing, also spelled aging, is the process of becoming older. The term refers especially to human beings, many animals, and fungi, whereas for example bacteria, perennial plants and some simple animals are potentially immortal. In the broader sense, ageing can refer to single cells within an organism, which have ceased dividing (cellular senescence) or to the population of a species (population ageing).
Ultraviolet radiation, which speeds the natural aging process, is the primary cause of early wrinkling. Exposure to UV light breaks down your skin's connective tissue — collagen and elastin fibers, which lie in the deeper layer of skin (dermis).
Without the supportive connective tissue, your skin loses strength and flexibility. Skin then begins to sag and wrinkle prematurely.
Smoking can accelerate the normal aging process of your skin, contributing to wrinkles. This may be due to changes in the blood supply to your skin.
Facial movements and expressions, such as squinting or smiling, lead to fine lines and wrinkles. Each time you use a facial muscle, a groove forms beneath the surface of the skin. And as skin ages, it loses its flexibility and is no longer able to spring back in place. These grooves then become permanent features on your face.
Wrinkles can come in many different forms. However, there is a type of wrinkle, which everybody has they are called expression lines.
Typically, these tend to appear around the mouth and forehead areas as a result of your most frequent facial expressions. Expression lines, however, are not really true wrinkles, because everyone has them and they do not occur as a result of the ageing process.
If you want to minimize the appearance of expression lines, you need to avoid contorting your face when you feel a certain way. This, however, can be hard to do, as people often form facial expressions through habit and without realizing what they are doing.
Fine lines/creases are the first type of proper wrinkle that appears on the face as a result of the aging process. Fine lines are like mini wrinkles. They are very thin, but not very deep. The can however, progress to larger and deeper wrinkles later on.
Fine line occur naturally as a result of aging, but they can also occur prematurely due to having dry skin, smoking cigarettes, not eating enough fat, not getting enough protein in your diet and not getting enough Vitamin C.
Fortunately, fine lines are the easiest type of wrinkle to prevent providing you have a good skin care routine and look after your skin and body well.
