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 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.
What is in between human ribs?

They are motor nerves which lead to the diaphragm and the intercostal muscles
What important structures are found in 6th intercostal space?
In the 6th intercostal space, important structures found include the internal mammary artery and vein, and the intercostal muscles and nerves. Additionally, in the left 6th intercostal space, the cardiac apex is located.

How are nerves formed?
Nerves are formed in a late stage of development, when some of the cells composing the nerve cord and the brain send out long fibers bound together in bundles (nerves).
