When a reflex arc consists of only two neurons in an animal (one sensory neuron, and one motor neuron), it is defined as monosynaptic. Monosynaptic refers to the presence of a single chemical synapse.he integration center is always within the central nervous system. 4) Motor Neuron: Conducts efferent impulses from the integration center to an efferent organ. 5) Effector: Muscle fiber or gland cell that responds to the efferent impulses (by contracting or secreting).

Find LED lights >. The technology that drives LEDs (light emitting diodes) is called solid state lighting or SSL. This means light is not emitted from a vacuum (as is the case with incandescent lights) or from a gas (like CFL lights), but from something solidâ a semiconductor.
