Effectors are organs that respond to stimuli by producing an action. Muscles act as effectors by contracting to produce movement, whereas glands secrete substances. Sensory organs, however, serve as receptors, detecting stimuli rather than responding. Therefore, muscles are correctly identified as effectors.
