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.

What muscle attaches to the cartilage of ribs 5 6 and 7?
The muscle that attaches to the cartilage of ribs 5, 6, and 7 is the rectus abdominis. This muscle is part of the anterior abdominal wall and plays a key role in flexing the trunk and stabilizing the pelvis. It connects to the costal cartilages of these ribs, contributing to its function in movements like sitting up and bending forward.
Which abdominal region is covered by the lower ribs?
The right and left hypochondriac abdominal regions are covered by the lower ribs.
Which muscles cover the ribs?
The intercostal muscles cover the ribs.
Where are the rectus abdominis in the musculatory system?
It is a vertical muscle on the front of the body that attaches to the 5-7th ribs and the pubic bone. So it is in the abdominal area. It is often referred to as one of the muscles that comprise the core. Their main job is the help balance the spine, so they are very important for good posture and also breathing.
What is the structure that attaches the ribs to the sternum?
The structure that attaches the ribs to the sternum is called the costal cartilage. It is a strip of hyaline cartilage that connects the bony rib to the sternum, allowing for flexibility and movement during breathing.
What happens to you ribs when you exhale?
The ribs lower during exhalation. During forced exhalation, the quadratus lumborum muscle stabilizes the 12th rib while the internal intercostal muscles and transverse thoracic muscle pull the ribs downward forcefully to decrease the volume of the thorax.

External obliques include what ribs?
The external oblique muscles originate from the fifth to the twelfth ribs. They are situated on the sides of the abdomen and play a crucial role in trunk rotation and lateral flexion. The fibers of these muscles run diagonally downward and medially, contributing to the overall structure and function of the abdominal wall.
What muscle attaches onto the cartilage of the ribs five through seven?
None! You are thinking of the external intercostal muscle which attaches to the *bone* of the ribs. However, at the cartilage of the rib the muscular portion is replaced by the external intercostal *membrane.* Muscles produce force on their attachments, causing piezoelectric force which eventually forms the bony landmarks you learn in anatomy lab.
