The right answer is False. (An important element missing from the definition of motor unit are motor neurons.)
A motor unit is composed of an alpha motor neuron and the muscle fibers it innervates.
Groups of motor units often work together to coordinate the contractions of a single muscle. All motor units that serve the same muscle are considered to be a group of motor units. The number of muscle fibers connected to each unit can vary: the muscles of the thigh can have up to a thousand fibers per unit, the muscles of the eyes can have only ten. In general, the number of muscle fibers involved in a motor unit is a function of the muscle's need for its refined movement: the more the muscle will need a fine movement, the less the motor unit will involve synapses with the muscle fibers.

Answer:
O. Living will.
Explanation:
A living will is a will made by a person stating his/ her choice of care or medication if or when the person becomes so sick and unable to communicate. In simple terms, it is a statement or directive written by a person stating his/ her desire on what type of medication or care he/she must be given when the person gets too sick and dying.
These types of will are written by individuals to give instructions or wishes to be carried out regarding end-of-life medical care and treatments that must be administered to that person. And as such, living will override other authorization papers such as organ donor cards, physician's directives, or even the power of attorneys.
Thus, the correct answer is the first option.
