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.
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 ribs * the internal intercostal muscles, which aid in forced expiration (quiet expiration is a passive process). They originate on ribs 2-12 and have their insertions on ribs 1-11. The internal intercostals are responsible for the depression of the ribs decreasing the transverse dimensions of the thoracic cavity. * the innermost intercostal muscle, the deep layers of the internal intercostal muscles which are separated from the them by the neurovascular bundle. 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.
Intercostal means anything found between the ribs
The intercostals is a muscle located between the ribs
An intercostal is any of the muscles between the ribs of an animal, or, in a nautical sense, hull reinforcing inserted between frames or bulkheads of a boat.
Some of the synergist muscles in the human body are the masseter, temporalis, supraspinatus, and the extensor digitorum. Examples if the antagonist muscles are the flexor digitorum superficial is, triceps brachii, extensor carpi radials longus, and the internal intercostals.

The definition of psychrophiles are extremophilic organisms that are capable of reproduction in cold temperatures.
The Intercostals stabilize the rib cage and assist in respiration

intercostals
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
The diaphragm and the intercostals are muscles that help breathing. When you excerise they work harder because it is harder to breathe.
Yes.
