Nerves and tendons are distinctly different. 1. Nerves refer to the bundle of nerve fibers in the nervous system that consists of multiple nerve fibers. The peripheral nerves include the nerve nuclei and the structures below the nerve nuclei, which are mainly used to conduct nerve impulses and to innervate the sensations and movements of the body, smooth muscles, heart muscles and glands, and the sense of taste. The ligaments, a dense connective tissue, play the role of contraction of muscles, joint movement and fixation. The nerves are mainly located in the muscles, tendons do not have the distribution of nerves, muscle contraction, joint activities need to be completed through the innervation, the two are indispensable.
