okay... the question is just simple :shock:

Isn't it that the abdomen is practically unprotected by a skeletal system. Why? i mean.. what are the advantages of such structural arrangement?

well, the advantage is...we're more flexible while moving, walking, running, sitting...etc.
it's all part of the evolution....

Isn't it a lil bit hard for us to have a skeleton-protected-abdomen? Oh, come on..I won't look handsome if I have a body like a water pipe...:lol:

I think Victor is correct. Just think of snakes' body: they have ribs (almost) along their body length, but have no sternum at all. The advantage is that snakes can flexibly roll and constrict ;)

I don't think it's of any particular advantage in humans, more of an indication of where we evolved from.

Think of cats. having no shoulder bones, they fit through small holes as well as greater.
