Ribs are classified as true ribs (1-7) because they attach directly to the sternum via costal cartilage; false ribs (8-12) because they attach to the sternum indirectly or not at all; and floating ribs (11-12) because they do not attach to the sternum at all.
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.
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.
The first seven ribs that connect with the thoracic vertebrae in the back and the sternum in the front are known as true ribs. These ribs are directly attached to the sternum via costal cartilage.
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.
rectus abdominus muscle
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.
Location: Based on the muscle's position or attachment points (e.g., pectoralis major). Shape: Describes the muscle's shape (e.g., deltoid). Size: Refers to the muscle's relative size (e.g., gluteus maximus). Number of heads or divisions: Reflects the number of separate parts in a muscle (e.g., biceps brachii). Direction of fibers: Describes the orientation of muscle fibers (e.g., rectus abdominis). Action: Indicates the main action performed by the muscle (e.g., flexor digitorum longus). Attachments: Based on the points where the muscle attaches to bones or other structures (e.g., sternocleidomastoid).

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.
