The Phrenic Nerve-Diaphragm and the External Intercostal Nerve-External intercostal muscles
during normal quiet expiration all respiratory muscles are at rest, it just depends on elastic recoil of lungs and chest. in normal inspiration the main muscle is your diaphragm
During inspiration, the primary muscles involved are the diaphragm and intercostal muscles. Muscles not involved in this process include the abdominal muscles and certain back muscles, such as the latissimus dorsi, which primarily assist with other movements rather than inhalation. Additionally, while accessory muscles like the sternocleidomastoid and scalene muscles may aid in deep or labored breathing, they are not required for normal inspiration. Thus, many core and upper body muscles do not play a direct role in the act of inhaling.
The accessory muscles of respiration are the sternocleidomastoid, scalenes, serratus anterior, pectoralis major and minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, and subclavius. The diaphragm is the main muscle of respiration (normal/relaxed breathing), assisted by the intercostals. No accessory muscles should be recruited during normal respiration unless there is a respiratory disorder. During quiet inspiration, the diaphragm and intercostals are activated. During quiet expiration, the inspiratory muscles relax and the elastic recoil of the lung tissue combined with intrathoracic pressure causes air to be pushed out of the lungs. There is little or no respiratory activity of the abdominals. When increased oxygen is required during physical activity e.g. when running, accessory muscles will activate to assist forced respiration.

During forced inspiration, the chest circumference can increase by approximately 2-5 cm due to the expansion of the ribcage and the muscles involved in breathing. This allows for more air to enter the lungs to accommodate the increased demand for oxygen during activities like exercise.
There are three layers of intercostal muscles: the External Intercosals, the Internal Intercostals and the Innermost Intercostals. These muscles are the one found between the Ribs in the ribcage and all are innervated by coastal nerves. At rest these particular muscles have very little function it is only during Forced Respiration (forced breathing not the cellular kind of respiration) that they come into action. During Forced Inspiration the Diaphragm pulls down as normal but to maximise increase the size of the Thoracic Cavity and suck in extra air the the external intercostals are activated. These muscles pull the ribs up and forwards. During normal expiration the elasticity of the lungs themsevels as well as action from the abdominal muscles shrink the thoracic cavity pushing the used air out again. This is not fast enough however for exercising, where forced expiration is required. Here the internal and innermost intercostals pull the ribs down and back compressing the thoracic cavity and forcefull (as aposed to passively) push the air out. Damage to any layer of the intercostal muscles is likely to make breathing during exercise much harder and less efficient.

Yes.
Inspiration is not a mathematical term. It, therefore, means what it does in normal usage.
No, Normal Spell Cards like Dark Hole can only be activated on your turn during your Main Phase 1 or 2.
