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.
rectus abdominus muscle
The serratus posterior superior muscle attaches onto the cartilage of ribs five through seven. This muscle is located in the upper back and is involved in assisting with respiration by elevating the ribs.
Ribs are classified according to their attachment to the sternum. The first seven pairs of ribs attach directly to the sternum and are called true ribs. Ribs 8-10 have cartilage that attaches to the cartilage of the seventh rib and are called false ribs. The eleventh and twelfth ribs do not attach to the sternum and are called floating ribs.
they have seven gills made of cartilage which are attached onto modified lungs
The scalenus anterior and the scalenus medius all insert into the first rib (the scalenus posterior inserts into the second rib). They originate from cervical vertebrae two to cervical vertebrae seven (C2 - C7). Each of the scalene muscles has several points of origin, which look like fingers from your spine.
Yes, the first seven pairs of ribs are considered false ribs because they do not attach directly to the sternum but rather either indirectly or not at all. They connect to the sternum through cartilage or do not connect at all in the case of floating ribs.
These are called true ribs. They each have their own cartilage connection to the sternum.
The surgeon must remove a portion of rib cartilage in order to construct a framework for the missing ear, and children younger than five may not have enough cartilage.

One difference is that fish are bony. Sharks have a skeleton made of cartilage (like in your nose or kneecap). Sharks have five to seven gill slits, while fish only have one. Fish have swim bladders for bouyancy, sharks do not.
