Where are intercostal muscles located?

• A. Between the vertebrae of the spine
• B. Between the ribs
• C. Along the abdominal wall
• D. Inside the thoracic cavity

Answer: (B)

Intercostal muscles are specifically located between the ribs. Their primary function is to facilitate breathing by expanding and contracting the ribcage. When these muscles contract, they help raise the ribs, increasing the thoracic volume and allowing air to be drawn into the lungs. Conversely, when they relax, they assist in lowering the ribcage, which aids in expelling air from the lungs. This muscle group plays a crucial role in the mechanics of respiration, making their location between the ribs essential for effective breathing.
