4. What muscles are located between the ribs and are responsible for assisting in breathing?

Quadriceps

Deltoids

Triceps

Intercostals

The intercostal muscles are located between the ribs and assist in breathing by expanding and contracting the ribcage to allow for inhaling and exhaling. Deltoids are located in the shoulder, quadriceps are located in the thigh, and triceps are located in the upper arm and are not involved in breathing.
