Hello! Just a quick one today...
As you can see from the title, I'm going to start from where I left off!
So today/tonight I'm going to finish off explaining the rest of the axial skeleton...
There's only one area left... I've talked about the skull, the spine and now... the chest!
So what bones do we have in this area?
Well we have 12 pairs of ribs and a sternum!
Starting with the ribs... they actually originate from the thoracic vertebrae (remember we talked about that last time?!.. Chris Tarrant... The Tarrant standing for thoracic vertebrae!). Anyway, these pairs of ribs extend around to form the chest wall! The 1st 3 pairs attach to the sternum (we'll be talking about that in a moment!). Now... the next 3 pairs of ribs have common cartilaginous attachment which is to the sternum. Finally, the last 2 pairs are free! (A lot to take in hence the spreading of blogs!)
So what are we left with... the sternum! This bone receives the upper 10 pairs of ribs (not the last 2 as they are free!) as well as receiving the clavicle. (We'll be covering the clavicle next time!)
Ok, so hope you found this useful!
See you all soon x
