Which of the following statements is TRUE? a) a motor neuron pool consists of a single motor neuron and the extrafusal muscle fibres it innervates b) muscles demonstrating fine control will tend to have small motor units. c) muscles demonstrating fine control will tend to have a small representation in the motor cortex. d) b and c e) none of the above are true 2 7. Which of the following statements is/are TRUE? a) IPSP bring the membrane voltage of a neuron away from the threshold b) IPSP can summate spatially and temporally c) once an EPSP is generated, an action potential results d) Hebb’s law involves changes in the frequency of EPSP e) a and b f) a and c g) all of the above 8.
