Where can you buy a real human skull?
In the United States, the sale and purchase of human skeletal material is far less regulated than most people seem to believe. The only federal law regulating human bones is narrowly focused on native American bones and grave goods. This law is known as NAGPRA, the Native American Grave Protection and Repratriation Act of 1990. Otherwise, at this writing (May 2008) only two states have laws that restrict ownership and transfer of human skeletal material: Georgia and Tennessee. In all other states it is legal to purchase and own human skeletal material as long as it complies with NAGPRA. There are several internet vendors who import human skeletal material from Asia for sale. Vendor - Osta in Canada.
In Canada unless you are becoming a doctor that requires this then beware! Students can get human skeletons and skulls alone, but often proof is needed as to why you need it. Some people donate their bodies to science and are called Cadavers. You can also go to specialty medical stores to buy this, but need proof as to why you need it.

Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.
How come your lower tail bone the top of buttcrack is so sore Im 25 weeks pregnant?
When you are pregnant the progesterone produced relaxes all your ligaments to enable the joints of your pelvis to alter slightly during labour. Sometimes this goes a little too far and what would be a little injury when not pregnant knocks a joint a bit further, this may be what has happened to you. You may have just sat down a bit hard, if you were not pregnant you wouldn't even have noticed. AS it is really bothering you I suggest you see your doctor and ask what pain medication you can take.
Mitochondrion what would happen if it did not function properly?
A zygote would not pass its "self-test". Embryos screen for several genetic conditions, including impotent mitochondria. The lysosomes of the developing child will explode and apopstosis or "programmed cell suicide" will occur. Theoretically however, an organism could live for a short time without mitochondria. We would just undergo anaerobic respiration but eventuall atrophy from the lactic acid by product. Please read about the Electron transport chain (to understand the importance of mitchondrion) and feel free to comment me if you would like a copy of an article I recently wrote about it.
What type of bone is a vertebra?
