Not on their own they dont. They can repair though.
Tendons attach muscle to bone.
Sand does not regenerate itself. It is constantly being broken down from larger rocks or minerals through weathering and erosion processes, but it does not have the ability to actively regenerate.
No, the cells of the receptor organ in the inner ear, called hair cells, do not regenerate in adult humans. Once damaged or lost, these cells do not typically regenerate, which can lead to permanent hearing loss. Research is ongoing to find ways to regenerate these cells in the future.
Tendons and muscles. It's the tendons that attach the bone to the muscle.
ligaments and tendons shorten and becomes less flexible with age
While the nerves (tendons) are not operating properly (sleep/dead) it does not matter how much you work out. Muscles will not grow or strengthen until the nerves regenerate. Until the nerves regenerate expect the muscles to atrophy.
