A motor unit consists ofQuestion 4Select one:a.One axon terminal branch and the myofibrils it controlsb.One neuron and all the skeletal muscle fibres it controlsc.One skeletal muscle fascicle and the neurons that control that fascicled.One skeletal muscle fibre and the neuron that controls that fibree.One skeletal muscle fibre and all the neurons that control that fibre

Which of the following statements regarding skeletal muscle motor units is/are correct?Question 19Select one or more:a.Small motor units allow for fine movements of the eyes and fingers.b.All motor units are activated in a muscle during muscle contraction.c.A motor unit comprises a single motor neuron and the muscle fibres it innervates.d.Large motor units allow for powerful movements such as extending the knee joint while kicking a soccer ball.e.When a motor unit is activated, all fibres within the motor unit contract.
