Accessory Muscles of Breathing

Overview

• Accessory muscles are supplementary muscles that assist with the process of breathing.
• They include the muscles of the neck, back, and abdomen.
• Normally, these muscles are not active during regular, quiet breathing.
• Their activation indicates an increased work of breathing, often seen in respiratory distress.

• Pectoralis Major

Clinical Significance
