question 49

Essay

Draw a diagram of the cerebral motor cortex and descending input to spinal motor neurons.Voluntary suppression of the knee jerk reflex originates in the motor cortex, which can send inhibitory signals to the motor neurons.If the left motor cortex is active, is the left or right knee jerk reflex suppressed or are both suppressed?
