"calcification"

yes

Very small, sometimes microscopic canals are called as canaliculus. They are usually present in bones.

All bones have bone marrow except joints if you count those as bones

Your blood is used all around your body, it helps all of your organs function. The blood circles the brain and helps it function without it you'd be a mindless vegetable. Blood circulates around the body helping you and your entire body to function.

you shouldn't eat blood unless you are a vampire

Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.

Lots and lots of bones

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.

no because they are at different parts of you body

Scapula, and the Lateral 3rd of the Clavicle.

Metacarpal bones

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.

A vertebra is classified as a bone. Vertebrae are found in the back and is known as an irregular bone.

any parts of hard tissue forming skeleton of most vertebrates

It is somewhat difficult to believe that a person who is capable of posting a question on this site (and correctly spelled, at that) doesn't know where the skull is located, but I will tell you anyway. The skull is a structure made of bone which contains the brain, and which is underneath the skin of your head.

tendons

tendons grasp onto bones holding the bones in place so when the muscles move, the bones will also move

Yes. People may tend to use their dominant side (if they're left or right handed) more often, causing it to be slighly stronger than the other. Usually the difference is very slight, but extreme differences can cause one side to be underdeveloped, resulting in awkward posture and gait. Any differences can usually be corrected by training of the weaker side with weights and other resistance exercises.

it has bone marrow

Depends on the severity of the breakage. Breaking your back isn't the biggest problem; your spinal column is meant to protect your spinal cord. Problems arise if your spinal column is wrecked enough that it affects the spinal cord (such as a broken spinal column slicing right through the spinal cord. This is why if you shouldn't try to move someone if you think their back is broken, because there's a chance you could do more damage). If the spinal cord is left intact, you could heal without any sort of neurological problems, but it takes quite some time and you have to be very careful while waiting for your back to heal.

If the spinal cord is damaged, there is a chance for neurological damage, as well as partial or complete paralysis. The degree of paralysis depends on the location of the damage (roughly: at around the neck, quadriplegia; below, paraplegia).

There are several ways to control cervical cancer pain, and you should ask your doctor which is right for you. You can take oral medications such as hydrocodone, or receive injections of it. You can also use a pain patch, a patch that is applied to the skin that releases pain medication throughout the day.

Cerebrospinal fluid can be found at the base of the spine for unknown reasons, and cause excruciating pain. Cerebrospinal fluid leaks can also result from surgery in that area or trauma.

It is the ulna, which is located on the opposite side of the forearm from the thumb.

Yes, it lacks them. They are found in the surrounding perichondrium.
