What clinical correlation may occur from lung irritation due to inhalation of toxins?

Lung irritation due to the inhalation of toxins can lead to somatic manifestations primarily in the upper thoracic and midcervical regions due to the interconnected nature of the respiratory system and the nervous system. The upper thoracic spine houses the vertebrae and associated soft tissues that correspond to the spinal segments innervating the lungs. When toxins irritate the lungs, it often triggers a reflex response that can result in muscle tension or dysfunction in these areas, particularly in the upper thoracic spine, where sympathetic innervation to the lungs originates.

Additionally, the midcervical region is involved because it corresponds to the upper parts of the sympathetic nervous system that also influence lung function. This anatomical and physiological connection explains why somatic manifestations occur in these regions specifically. Understanding the connection between the respiratory system and somatic responses in the spine is vital in chiropractic practice, as it underscores the importance of considering systemic health issues that may further influence musculoskeletal conditions.
