3. How do muscles work?
what is the function of the ribcage?
Answers
Answer:
The intercostal muscles are a group of muscles found between the ribs which are responsible for helping form and maintain the cavity produced by the ribs. The muscles assist with expansion and contraction during breathing. The intercostal muscles consist of 11 muscle trios in humans.
Answer:
Muscles provide the tug on the bones needed to bend, straighten, and support joints. Muscles can pull on bones, but they can't push them back to their original position, so the muscles work in pairs of flexors and extensors. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.
The rib cage protects the delicate internal organs like heart, liver and lungs. The rib cage also take part in our breathing movement.
