Nerve

Explanation:

Nerves are thin, whitish structures made up of sets of nerve fibers and connective tissue responsible for transmitting nerve impulses from the brain to the rest of the body. These structures leave the brain and spinal cord, form various branches, reaching all parts of the body.

To form the nerves, each nerve fiber is first surrounded by a layer of connective tissue called endoneurium. Thus, these fibers are organized into bundles that, in turn, are covered by a new layer of connective tissue: the perineurium. Finally, the bundles are arranged in sets and are covered by the last layer of connective tissue, the epineurium. These connective tissues have blood vessels that supply the nerve fibers with oxygen and nutrients.
