What is the definition of intercostals?
That is a good question. You have twelve intercostal nerves going between your ribs. They supply the intercostal muscles and carry back the sensations. You have the brachial plexus and lumbosacral plexuses. They are complicated as on today. But long back in evolution scale they were parallel. There complicated arrangement tells the the movement of muscle mass during evolution.
The functions of the intercostal?
Intercostal muscles are several groups of muscles that run between the ribs, and help form and move the chest wall. There are three principal layers; * the external intercostal muscles, which aid in quiet and forced inhalation. They originate on ribs 1-11 and have their insertion on ribs 2-12. The external intercostals are responsible for the elevation of the ribs, and expanding the transverse dimensions of the thoracic cavity. Located around the the ribs * the internal intercostal muscles, which aid in forced expiration (quiet expiration is a passive process). They originate on ribs 1-11 and have their insertions on ribs 2-12. The internal intercostals are responsible for the depression of the ribs decreasing the transverse dimensions of the thoracic cavity. * the innermost intercostal muscle Both the external and internal muscles are innervated by the intercostal nerves (the ventral rami of thoracic spinal nerves), and are provided by the intercostal arteries and intercostal veins. Their fibers run in opposite directions.

What is the Rib muscle?
There is no "rib muscle." Ribs are bones attached to the vertebral column in the back and the sternum anteriorly. There are muscles attached to the ribs - several, in fact. In between the ribs are the internal and external intercostal muscles, there are the pectoral muscles, the serratus anterior and serratus ventralis, the latissimus dorsi also attaches to the ribs. Internally, the diaphragm attaches to the inferior ribs. Many of the strap muscles of the back attach to the ribs. There are others as well.
