Nerves are to a great degree sensitive structures. They don’t have a tendency to be exceptionally adaptable and can get harmed on the off chance that they are extended even the smallest piece excessively. In the meantime, nerves are required in zones of the body that endure a great deal of extending and straining. Here’s an extraordinary illustration: When it opens its enormous mouth to bolster, the rorqual whale’s nerves extend to dramatically increase their resting length and back-all while making to a great degree sharp ‘clasp’- like turns-without being strained or broken. Be that as it may, how would they escape with treating their sensitive nerves like a group of bungee ropes?
