What are primitive, involuntary movements of infants that prime the neuromuscular system?

The correct choice refers to reflexive movements, which encompass the primitive, involuntary actions that are present in infants. These movements are crucial because they are automatic responses to specific stimuli, and they play a vital role in the development of the neuromuscular system. Reflexive movements include actions such as grasping, rooting, and sucking, which are essential for survival and learning in early infancy.

These movements help to lay the foundation for more complex motor skills as infants grow. By priming the neuromuscular system through these involuntary actions, the infant's body begins to coordinate muscle groups, ultimately leading to the development of voluntary movements.

In contrast, fundamental movements refer to basic physical skills that are developed later in childhood, such as running or jumping. Rudimentary movements involve the first voluntary motor actions that infants learn to control, such as crawling or walking. Specialized movements are complex motor skills that typically occur in later childhood and involve the development of specific skills for activities like sports or dance. Understanding these different categories of movement is essential for recognizing the stages of motor development in children.
