Detailed explanation-1: -Your phrenic nerve plays a critical role in your respiratory system to aid breathing. It’s the only nerve in your nervous system that provides motor (movement) function to your diaphragm. It sends signals that cause your diaphragm to expand and contract. These movements allow your lungs to inhale and exhale air.
Detailed explanation-2: -The receivers then convert the radio waves into stimulating pulses. These pulses are then sent down the electrodes to the phrenic nerves, causing the diaphragm to contract. This contraction causes the patient to inhale. When the pulses stop, the diaphragm relaxes and the patient exhales.
Detailed explanation-3: -The phrenic nerve activates contraction of the diaphragm that expands the lungs and thereby draws air into them.
