The pectoralis minor and the scalenes, directly raise the uppermost ribs. When these muscles relax, the force of gravity lowers them. The muscle groups used to move the Rib Cage, thus changing thoracic volume, are all in one big group called the Intercostals. There are three layers of intercostals. The External Intercostal raise the ribs up and out to increase thoracic volume. The Internal Intercostals depress the ribs down and in to decrease the thoracic volume. The Innermost Intercostals help the internal intercostals.
The Intercostal muscle
Actually it's the external intercostal muscle found on page 208 of 10th edition Lab Manual by Elaine N. Marieb.
The diaphragm located at the bottom of the lungs cause them to inflate and deflate. When inflated, that lungs which are located beneath the rib cage causes it to rise. When deflated, the lungs let the rib cage lower back to its rest position

Name the muscles that raise and lower the ribs in a fetal pig?
The external intercostal muscles raise the ribs during inhalation, while the internal intercostal muscles lower the ribs during exhalation in a fetal pig.
Which muscles cover the ribs?
The intercostal muscles cover the ribs.
How does the sternomastoid muscle help with breathing?
If the head of the neck is fixed, then it is possible for the muscles to raise the clavicle and manubrium sterni, and hence the ribs, so that they act as accessory muscles of respiration.
Name of muscles between ribs?
The intercostal muscles. Intercostal means "between ribs".
WHAT IS RIB 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.
Where are inter coastal muscles?
They are the muscles between the ribs
What are the two sets of muscles running between the ribs called?
The external intercostal muscles run between the ribs. They are responsible for elevating the ribs during inhalation. The internal intercostal muscles are situated deeper and help with forced exhalation by depressing the ribs.

What muscles play a role in inspiration besides diaphragm how do they aid inspiration?
In addition to the diaphragm, several muscles assist in inspiration, including the intercostal muscles, scalene muscles, and sternocleidomastoid. The intercostal muscles elevate the ribs and expand the thoracic cavity, while the scalene muscles lift the first two ribs, further increasing lung volume. The sternocleidomastoid helps raise the sternum, enhancing overall chest expansion. Together, these muscles work to create a negative pressure in the thoracic cavity, allowing air to flow into the lungs.
Where are the intersoastal muscles located?
in between your ribs
What muscles are attached to bones?
ribs
What are the muscles behind the ribs in the back responsible for?
The muscles behind the ribs in the back are responsible for supporting the spine, aiding in breathing, and assisting in movements of the upper body.
