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 intercostal muscles are located between the ribs and aid in the breathing process by expanding and contracting the chest cavity to help with inhalation and exhalation. There are three layers of intercostal muscles: external intercostals, internal intercostals, and innermost intercostals.
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.

Which muscle will depress the scapula or elevate the ribs?
The muscle that depresses the scapula is the lower trapezius, while the muscle that elevates the ribs is the external intercostals.
Choose the term that best matches this definition.?
Please provide the definition for me to identify the matching term.
What is the defineition of definition?
A definition is a statement that explains the meaning of a word, phrase, concept, or term, often providing clarity and understanding of its intended usage and interpretation. It helps to establish a common understanding among individuals when communicating about a particular subject or idea.
What is A basic life form happened to arise from nonliving matter is a definition of .?
That is a definition of abiogenesis, the scientific concept of life arising from non-living matter.
What is the one word definition for bios?
"Life."
What is the function of the intercostals?
The Intercostals stabilize the rib cage and assist in respiration
What are in the thoracic cavity?
The intercostals and the diaphragm.
What is the Diaphragm's synergist muscles?
intercostals
What muscle flexes when Intercostals are flexed?
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
Do interchondral external intercostals exist?
No, interchondral external intercostals do not exist. The external intercostal muscles are located between adjacent ribs and are involved in respiratory movements. However, there is no specific structure known as interchondral external intercostals.
The immediate effects of exercise on the Diaphragm and intercostals?
The diaphragm and the intercostals are muscles that help breathing. When you excerise they work harder because it is harder to breathe.
Are the external and internal intercostals muscles?
Yes.
What respiratory group stimulates the intercostals?
Dorsal
What moves the ribcage?
external and internal intercostals
What muscles are in the thoracic cavity?
The intercostals and the diaphragm.
What muscle has fibers on a transverse plane?
Internal Intercostals
What skeletal muscles are always contracting?
Diaphragm and intercostals
