The scientific name for the true ribs is the costae verae, which is derived from the Latin language. The true ribs are the first seven pairs of ribs,…
Beside above, what is the anatomical name for the rib muscles?
There are five muscles that make up the thoracic cage; the intercostals (external, internal and innermost), subcostals, and transversus thoracis. These muscles act to change the volume of the thoracic cavity during respiration.
Then, what are the three types of ribs?
As such, ribs can be allocated to one of three distinct types; true (vertebrosternal) ribs, false (vertebrochondral) ribs and floating (vertebral, free) ribs.
What is the scientific name for backbone?
Vertebral column, also called spinal column, spine, or backbone, in vertebrate animals, the flexible column extending from neck to tail, made of a series of bones, the vertebrae.

What is the main function of rib cage?
The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration.
What connects ribs together?
The rib cage is collectively made up of long, curved individual bones with joint-connections to the spinal vertebrae. At the chest, many rib bones connect to the sternum via costal cartilage, segments of hyaline cartilage that allow the rib cage to expand during respiration.
What animals have no ribs?
Other animals
Not all species possess both types of rib, with the dorsal ribs being most commonly absent. Sharks, for example, have no dorsal ribs, and only very short ventral ribs, while lampreys have no ribs at all.
Why are ribs 8/12 called false ribs?
The false ribs include rib pairs 8-12. … Because the false ribs attach to the vertebrae posteriorly and costal cartilage anteriorly, anatomists sometimes call the false ribs vertebrochondral ribs (vertebro = vertebrae; chondral = cartilage).
What is the shortest rib?
twelfth rib
What are the names of human ribs?
The first seven rib pairs known as the fixed or vertebrosternal ribs are the true ribs (Latin: costae verae) as they connect directly to the sternum; the next five pairs (eighth to twelfth) are the false ribs (Latin: costae spuriae). The false ribs include both vertebrochondral ribs and vertebral ribs.
What is true rib?
Medical Definition of True rib
