Question

Quizplus · Accepted Answer

Infant reflexes are not voluntary actions and are controlled by the spinal cord and brainstem. As the infant develops, these reflexes are incorporated into more complex actions that are under voluntary control. Therefore, most infant reflexes disappear during the first year after birth as they become integrated into more complex, voluntary actions.
