What reflex ensures that the opposite limb extends to maintain balance during a withdrawal action?

• A. Flexion reflex
• B. Stretch reflex
• C. Crossed extension reflex
• D. Withdrawal reflex

Answer: (C)

The crossed extension reflex is responsible for extending the opposite limb to maintain balance when a withdrawal action occurs. This reflex is an important protective mechanism of the body. When one limb withdraws from a painful stimulus, the crossed extension reflex initiates an opposite response in the contralateral limb, providing stability and maintaining posture. Essentially, while one leg pulls away from the source of discomfort, the other leg tenses and extends to support the body, preventing a fall and ensuring coordination during a potentially precarious situation. This reflex integrates sensory input with motor output and highlights the body's ability to maintain equilibrium in the face of sudden changes in environment or stimulus.
