Nervous tissue, such as neurons in the brain and spinal cord, and cardiac muscle tissue in the heart, have limited regenerative abilities compared to other tissues in the body. Once damaged, these tissues often replace lost cells with scar tissue rather than functional tissue.
Mitosis is the process of cell division where two identical daughter cells are produced from one parent cell. Mitosis does not regenerate, but it plays a crucial role in growth, repair, and maintenance of tissues in multicellular organisms.
Nervous tissue and cardiac muscle tissue are two types of tissues that have limited capacity for regeneration. Injuries to these tissues can often lead to permanent damage or scarring, making it difficult for them to fully recover.
Planarian worms have the ability to regenerate into two new worms if cut in half because of their amazing regenerative capabilities. Each half is able to regenerate the missing parts, resulting in two separate worms.

An earthworm can regenerate its head and its tail. An example is, if you go dig a earthworm out from the ground and chop it in half then its head will grow a new tail and the tail will grow a new head. Eventually there would be two earthworms. If you cut an earthworm into four piece's then after a few weeks or even months there would be four earthworms. So if you think that if you cut an earthworm you are killing it you are wrong. But if you cut an earthworm into too many piece's, example twelve then you will kill the worm, and after that there is no way to bring it back to life.
Gap Junction
It will regenerate and become two and both of the parts will squirm around.
After the next two episodes then he will regenerate
Planaria can regenerate within a couple of weeks. The exact time can vary depending on factors such as the size of the planaria, the extent of the injury, and the environmental conditions. Generally, smaller injuries will heal faster.
The phloem and xylem tissues
Animals like sponges and coral colonies naturally fragment and reproduce. Many species of annelids and flat worms reproduce by this method. The animal splits and the two parts remake lost organs and tissues. The splitting is not preceded by the development of the tissues to be lost. Prior to splitting, the animal may develop furrows at the zone of splitting. The headless fragment has to regenerate a complete head.
