"motor nerve" の定義と意味

What is a "motor nerve"?

A motor nerve, in its singular form, refers to a specialized bundle of nerve fibers that transmit signals from the brain and spinal cord to the muscles of the body. These nerves are responsible for controlling voluntary movements, allowing us to perform various actions such as walking, speaking, and grasping objects. Motor nerves play a vital role in coordinating muscle contraction and providing the necessary communication between the central nervous system and the muscles. They are essential for our ability to move and interact with the environment.
