How are the ribs classified on the basis of their attachment to the sternum?
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.
What is the anterior neck muscle which attaches to the ribs is?
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.
Are the first seven pairs of ribs considered false because of their posterior and direct anterior attachments?
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.

What is the scientific name for true ribs and false ribs?
The "true" ribs are the first 8 ribs of the horse's rib cage (there are 18 total ribs). They are the true ribs because the attach to both the vertebrae above them and the sternum below. I found this in a book-Chapter 35 of Saddles by Russel H. Beatie. Hope this helps.
What muscle attaches onto the the cartilage of ribs five through seven?

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.

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.

What is the difference between a shark and a fish anatomy?
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.
