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.
The muscles of respiration are also called the 'breathing pump muscles', they form a complex arrangement in the form of semi-rigid bellows around the lungs. All muscles that are attached to the human rib cage have the inherent potential to cause a breathing action.
Additional muscles can be used if a bigger breath is required. When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs.

30 Ιουλ 2022 · Additional muscles can be used if a bigger breath is required. When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs.
5 Ιουν 2023 · Breathing is a complex process that relies heavily on the coordinated action of the muscles of respiration and the control center in the brain. The primary function of the lungs is to facilitate gas exchange between inspired air and the circulatory system.
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.
