The definition of asinine is to be silly, stupid or ridiculous. An example of asinine is a foolish prank played on a friend.
In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper.
As a practicing anatomist, I would say that there are 29 vertebrae, as in 29 vertebral elements (but you can't say 29 ossification centers, because each is made of multiple centers). These fuse into 24 free vertebrae, the sacrum (5 fused vertebrae) and one coccyx, which is variably fused. share | improve this answer edited Dec 27 '17 at 4:29
