Where are the ribs in relation to the pectoralis muscle?

Explanation:
The pectoralis major sits on the anterior chest wall, covering the front surface. The ribs and intercostal muscles lie deeper behind that muscle, toward the body’s back, so the ribs are posterior to the pectoralis muscles. In ultrasound terms, you’d see the superficial pectoralis layer overlying the deeper rib cage; the ribs themselves are not in front of or above the muscle but behind it.
