What is the nerves that carry activating impulses to the muscles of inspiration?

The nerves that carry activating impulses to the muscles of inspiration are primarily the phrenic nerves. These nerves originate from the cervical spinal cord (C3-C5) and innervate the diaphragm, the primary muscle of respiration. Additionally, the intercostal nerves, which arise from the thoracic spinal nerves, stimulate the intercostal muscles that assist in expanding the thoracic cavity during inhalation. Together, these nerves coordinate the process of breathing.
