The phrenic nerve of the cervical plexus. Cervical Spinal nerves 3-5.
During inhalation, the diaphragm and intercostal muscles contract, causing the chest cavity to expand and the lungs to fill with air. This expansion of the chest causes the ribcage to move outward and upward, which can give the appearance of the chest swelling.
The part of the nervous system that works closely with the respiratory system for inhalation is the phrenic nerve. It controls the diaphragm, the primary muscle involved in breathing. Stimulation of the phrenic nerve causes the diaphragm to contract, enabling the process of inhalation.
During inhalation (inspiration) the ribs move up and out. Volume in the thorax increases whilst pressure decreases. The diaphragm goes down and the intercostal muscles contract. Just to let you know, exhaling (expiration) is just the opposite to inspiration. :) - Hope I helped :)
During inhalation, the diaphragm contracts and moves downward, increasing the volume inside the chest cavity. This increase in volume causes a decrease in pressure, leading to air rushing into the lungs to equalize the pressure. As a result, the chest expands to accommodate the incoming air.
Inhalation is caused by the contraction of the diaphragm and the external intercostal muscles. This causes the chest cavity to expand, creating a negative pressure that allows air to flow into the lungs.

The intercostal muscles, (muscles between the ribs), contract.
