They are called the intercostal muscles
Intercostal spaces
In between human ribs are layers of intercostal muscles, nerves, and blood vessels that help support and protect the ribcage. Additionally, there is a thin layer of connective tissue called the intercostal membrane that separates each rib.
Your ribs are flexible due to the cartilage that connects them to the sternum and helps absorb shock. Additionally, the joints between the ribs and the spine allow for some movement. The ribs also have intercostal muscles between them that help with breathing and movement.
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 costal cartilage connects the ribs to the sternum, allowing flexibility for expansion and contraction during breathing. The intercostal muscles between the ribs also play a key role in this movement.
The muscles that are located between the ribs are called the intercostal muscles. Inter- means 'between', and costa derives from the Latin for 'rib'.
The intercostal muscles. Intercostal means "between ribs".

intercostal muscle
The intercostal muscles are the muscles that lie between the ribs and form the chest wall. Their function is to aid inhalation and exhalation.
intercostal muscles
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.
The term 'inter' stands for between while 'costal' refers to the ribs, hence 'between ribs'. That is there location
Between the ribs ie. intercostal muscles.
The intercostal muscles cover the ribs.
