Motor neurons.
A twitch is when only one muscle is affected, usually the result of a nerve impulse, while a spasm is when multiple muscles contract involuntary, due to a chemical imbalance.

The connective tissue that wraps around nerve cells is there to keep them apart. It also functions to join them all together into what we call a nerve, which is really a bunch of nerve cells together.
Nerve agents effect the junctions between nerve cells. Nerve agents prevent signals crossing the nerve junctions so all communication between nerve cells stops and no signals can get through from the brain.
The sternocleidomastoid and trapezius muscles are controlled by the accessory cranial nerve. Some call it cranial nerve XI.
Gray matter is what you call the nerve tissue in your brain because the cells are gray in color.
The slender nerve fiber is called an axon. It is the long, slender projection of a nerve cell that transmits electrical impulses away from the cell body to other neurons, muscles, or glands.
Nerves are like trees. The have branches call axons.
The heart is known to be myogenic because the muscles that contract the heart through a pulse are themselves called myocytes.
You can pretty much just call it muscular endurance. Stamina might be an appropriate word also.
The tissues that help bones to move are called muscles. Muscles are connected to bones by tendons, and they contract to create movement at the joints. There are three types of muscles in the body: skeletal, smooth, and cardiac, with skeletal muscles being the primary type responsible for voluntary movement of bones.
