Regeneration is a notion that comes from regeneration, a Latin term. It is about the process and the result of regenerate (get something to regain its shape or state, carry out a treatment so that a material can be reused, get a person put aside harmful behavior).
For example: “Scientists investigate how to facilitate cell regeneration”, “The Government studies a new strategy for urban regeneration”, “The regeneration of forests will not be possible as long as the human being maintains this kind of behavior”.
In the context of biology, we speak of regeneration to refer to the process carried out by certain organisms to recover or reestablish absent cells, tissues, or organs. The regeneration capacity varies according to the species: while some can regenerate complete limbs, others hardly manage to achieve any kind of regeneration.
A example regeneration is what the lizard or salamanca when it loses its tail and it grows back. The mobsters They are also species with an amazing capacity for regeneration: if they are cut in half, a new head grows in the middle where the tail was left and vice versa.
Tuberlarians are also known by the name of planarians, and it is a kind of flatworms small in size. They generally live in the sea or in fresh water, although some of them have been adapted to humid terrain. To move they use cilia (thread-like cellular organelles) and to search for food they actively excavate their environment. Almost all tuberlars are carnivores.
A tiny portion of your body is enough for you to carry out a complete regeneration; more precisely, they are able to achieve it starting from 1/279 of your body, something that is fascinating for science, since it departs considerably from our regenerative capacities. According to studies carried out in this regard, it is estimated that tubers need two weeks to achieve regeneration, although this varies according to the portion of the body and the species in particular.
It is known that tuberlars need more time to regenerate the Body starting from the head than the other way around. Regarding the regeneration rate, it is not proportional to the size of the individual; In other words, a 20-millimeter long planarian has the same rate as a 1-centimeter one. However, it does have a relationship with their nutritional status, with which the nutritional resources of each individual make a notable difference in this process.
The lizard, for its part, can only regenerate its tail, but this does not make it any less interesting. First of all, it should be mentioned that it is not necessary that they lose it in a confrontation, but that they often dispose of it voluntarily to mislead their predators. This happens thanks to the limb shaking for a while, allowing the animal to escape stealthily.
Is species it also needs its tail for locomotion, for courtship, and for storing fat, which it then uses in times of food shortage or illness. It should be noted that the regenerated limb is not identical to the original, but shorter and with a less intense color, in addition to not having vertebrae or scales. Interestingly, it happens very often that regeneration results in two tails.
The human being it also has regeneration capacity. The nails, the skin, the hair and the bones they can regenerate. The same goes for the liver, which increases in size when a part is missing. In this case, the missing fragment does not grow again, but the remaining portion increases in size in order to compensate for what is missing.
