The diaphragm is the primary muscle that initiates breathing. When it contracts, it moves downward, creating a vacuum that allows air to flow into the lungs. This process is essential for inhalation, while relaxation of the diaphragm facilitates exhalation. Other muscles, such as the intercostal muscles, assist in the process but the diaphragm is the main driver.
The specific event that initiates a muscle contraction is the release of calcium ions within the muscle cell. This triggers a series of chemical reactions that ultimately lead to the sliding of actin and myosin filaments, resulting in muscle contraction.
The diaphragm. It is the only muscle that causes breathing.
the muscle spindle detects excessive stretch within the muscle , it response and makes the muscle contract

What are some reasons that your diaphragm muscle would hurt when breathing in and out?
It is the diaphragm.
The diaphragm muscle plays a main role in breathing. This muscle pushed the lungs up and down to take in or push out air.
Your lungs are the largest breathing muscle in your body.
Yes, a pulled chest muscle can cause pain when breathing due to the movement of the ribcage and the strain on the muscle during inhalation and exhalation.
For relaxed breathing, called tidal breathing, all you need is the diaphragm muscle.
The main muscle used is the diaphragm. Also, the intercostal muscle.
