. Advanced biology. Biology; Physiology; Reproduction. AXON rons is commonly known as a synapse. The sense organs, known as receptors, receive the stimulus which starts the nerve current. The ends of the nerve fibers of these organs are on the outside (skin) of the body. The muscles or glands are called effectors because they bring about activity. An axon that connects with a sense organ is called an in-going, sensory, or afferent axon; one that connects with a muscle or gland is an out- going motor, or efferent axon. The neurons possessing these axons mav be either sensorv or motor neurons.
