Which of the following reflexes is particularly important in maintaining balance and often accompanies the flexor reflex in weight-bearing limbs?

• A. deep tendon reflexes
• B. abdominal reflexes
• C. withdrawal reflexes
• D. superficial reflexes
• E. crossed extensor reflexes

Answer: (E)

Verified step by step guidance

1. Understand the context of the problem: Reflexes are automatic responses to stimuli that help protect the body and maintain homeostasis. In this case, we are focusing on reflexes that help maintain balance.
2. Identify the reflexes listed: The problem provides several types of reflexes, including deep tendon reflexes, abdominal reflexes, withdrawal reflexes, superficial reflexes, and crossed extensor reflexes.
3. Consider the function of each reflex: Deep tendon reflexes involve muscle contraction in response to stretching, abdominal reflexes involve contraction of abdominal muscles, withdrawal reflexes involve pulling away from a painful stimulus, and superficial reflexes involve skin stimulation. Crossed extensor reflexes are involved in maintaining balance.
4. Focus on the role of crossed extensor reflexes: This reflex is crucial for balance, especially in weight-bearing limbs. When one limb withdraws from a painful stimulus, the opposite limb extends to support the body's weight, maintaining balance.
5. Conclude that the crossed extensor reflex is the correct answer: Given its role in balance and coordination, particularly in weight-bearing situations, the crossed extensor reflex is the reflex that accompanies the flexor reflex to maintain balance.
