Central pattern generators produce what type of movement patterns?

• A. Stereotyped movement patterns
• B. Random movement sequences
• C. Voluntary goal-directed sequences
• D. Coordinated reflexes

Answer: (A)

Central pattern generators are neural circuits that produce rhythmic, repetitive motor outputs automatically. They generate movement in a fixed, repeatable sequence—like the stepping rhythm in walking or the breathing cycle—without needing every action planned or guided by senses. Higher brain centers or sensory feedback can modulate the tempo, strength, or pattern, but the basic rhythmic output comes from the network itself. That automatic, repeatable nature is what makes the movements stereotyped. It’s not a random sequence, not a consciously directed goal sequence, and while reflexes can be patterned, CPGs specifically generate sustained, rhythmic motor patterns rather than single reflex responses.
