What comprises the thorax musculature?

The thorax musculature primarily includes the muscles involved in respiration, which are essential for the process of breathing. These muscles underlie the expansion and contraction of the thoracic cavity, facilitating the inflow and outflow of air from the lungs. The diaphragm, a dome-shaped muscle at the base of the thoracic cavity, plays a crucial role in inspiration by flattening as it contracts, increasing the volume of the thoracic cavity. Additionally, intercostal muscles, located between the ribs, assist in elevating the rib cage during inhalation and lowering it during exhalation, working alongside the diaphragm for efficient respiration.

Understanding the thorax musculature's role in respiration is vital, as it directly relates to pulmonary function and gas exchange in the body. The focus on respiratory muscles distinguishes them from other muscle groups present in the upper limbs, abdomen, or those that support the vertebral column, which do not share the same specialized function within the thoracic region.
