The muscles of respiration comprise three groups: the diaphragm, the intercostal and accessory muscles, and the muscles of the abdomen (Fig 1). All three groups have inspiratory and expiratory function and work together in intricate ways.

22 Οκτ 2024 · The use of accessory muscles typically indicates increased work of breathing and may be a sign of respiratory distress or disease. However, during intense physical exertion or specific situations like high altitude, temporary use of accessory muscles can be considered normal.
5 Ιουν 2023 · Examples include muscular dystrophies, such as Duchenne muscular dystrophy, and motor neuron diseases, such as poliomyelitis. Respiratory muscle weakness eventually occurs in neuromuscular diseases, causing hypoventilation and resultant hypoxia and hypercapnia.
31 Αυγ 2023 · Therefore, they are used as accessory, or secondary muscles in pulmonary ventilation. The scalene muscles also play a role in inspiration. They consist of scalenus anterior, scalenus medius and scalenus posterior.
21 Αυγ 2021 · Muscles elevating chest cage during respiration are called muscles of inspiration, while muscles depressing chest cage are termed as muscles of expiration. Inspiratory and expiratory muscles support inspiration and expiration during exercise or COPD or weaning.
12 Ιουν 2019 · This review is a comprehensive description of all muscles that assist lung inflation or deflation in any way. The developmental origin, anatomical orientation, mechanical action, innervation, and pattern of activation are described for each respiratory muscle fulfilling this broad definition.
The muscles between the ribs (intercostal muscles) are secondary muscles that support the breathing process. When the diaphragm contracts (moves down) and the muscles of the rib cage contract, air will move into your lungs. The movement of air in and out of your lungs is called “ventilation.”
