Explanation:
Detailed explanation-1: -Answer and Explanation: The smaller muscle fiber to motor neuron ratio for muscles responsible for precision is a result of the need for accuracy. When we move our arms, the brain sends signals to the muscles telling them what type of movement to make and how much force they should use.
Detailed explanation-2: -A motor unit is made up of a motor neuron and all of the skeletal muscle fibers innervated by the neuron’s axon terminals, including the neuromuscular junctions between the neuron and the fibres.
