What type of nerves are responsible for carrying impulses or messages from the brain?

Motor nerves are responsible for carrying impulses or messages from the brain to various parts of the body, primarily to muscles. These nerves relay signals that instruct muscles to contract or relax, enabling voluntary movements such as walking, grasping, or any other physical activity.

This function is essential for coordinating actions and responses based on the brain's commands. Distinct from sensory nerves, which transmit information from the body to the brain, motor nerves focus specifically on the delivery of messages that control behavior and physical actions. Understanding the role of motor nerves is crucial for anyone in the field of cosmetology and nail technology, as it helps connect the understanding of body functions with practical applications in their work.
