Question
In a withdrawal reflex, flexor muscles on the affected side of the body contract. Simultaneously, a ______ reflex is initiated which causes the contralateral extensor muscles to contract in order to help maintain balance.Multiple choice question.crossed extensorjerkstretchreciprocal
Solution
The correct answer is "crossed extensor". This reflex helps to maintain balance when the withdrawal reflex is initiated. For example, if you step on a sharp object with your right foot, the withdrawal reflex causes you to lift your right foot (flexor muscles contract). Simultaneously, the crossed extensor reflex causes the extensor muscles on your left leg to contract, helping you maintain balance so you don't fall over.
