Thoracic vertebrae differ from the other vertebrae in that they have - costal facet

Each vertebra have a ventral body, or centrum, surmounted by a Y-shaped neural arch. Together the centrum and neural arch surround an opening, the vertebral foramen, through which the spinal cord passes.

A costal facet is a site of connection between a rib and a vertebra.The transverse costal facet joins the rib to the transverse process of a vertebra, and the inferior costal facet joins the rib to the lower part of the vertebra.Thoracic vertebrae are unique among the bones of the spine in that they are the only vertebrae that support ribs and have overlapping spinous processes.

Thus, Thoracic vertebrae differ from the other vertebrae in that they have - costal facet.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
