Question

Quizplus · Accepted Answer

The effector is the muscle or gland that performs the reflex act, such as contracting a muscle or releasing a hormone. It does not generate an electrical impulse to the CNS, as this is the role of the sensory neuron. There may be one or more synapses involved in the reflex arc, but this is not a defining characteristic of the effector.
