Skeletal System

I guess clavicle is the breastbone & collarbone is the chest bone. They are the same literally

External intercostal muscles are the ones between the ribs that help elevate them during inspiration.

Regular resistance exercise (weight lifting) and impact-based cardiovascular activity (such as running) can help to increase bone density. This effect suggests that such training, as part of a healthy lifestyle, can help to reduce the risk of osteoporosis

That's the natural formation of or conversion into bone.

Thanks to the process of ossification, moose antlers act as parabolic reflectors to enhance their sense of hearing!

Male and female giraffes have prominent horn-like structures called ossicones, thanks to the natural process of ossification.

Everything, except the mandible

There are many reasons that could cause this. I recommend seeing a doctor immediately as almost all instances of this are dangerous and/or life threatening. Possible reasons include: palpitations, mitral valve prolapse, halitosis, and myocardial infarction.

No, a finger nail is just potection for the tip of your finger.

The atlas is the very top vertebra in your spine. The head or skull rests on it, and is allowed to move in many directions. The atlas sits upon the axis vertebra - between them, they allow much more rotational movement than do other vertebrae. Also, the actual brain stem extends down into the atlas/axis pair. The spinal cord begins at the bottom of the axis bone.

probably the one that's completely surrounded by bone, the brain

Yes it OS indeed.

The nerve endings in your gluteus maximus react with your brain to cause a sensation some would call "pain."

It depends on the surface that you fall onto, however. Most notably, Dr. Brian Moore found in his research for his Harvard Medical School Dissertation that concrete is the most painful surface to fall upon.

You have 206 bones in your body. Amazing isn't it. A newborn baby has about 300-350 bones in their body.

An unla is a bone that is beside the radius the ulna is a long bone and is in prismatic form

Most of ab baby's bones are made up of cartilage that eventually hardens into bone

WHERE TWO BONS JOIN TO CREATE MOVEMENT

In many research projects performed, there were findings of 8.6 (+or-) 1.6 % of T lymphocytes found in the total bone marrow lymphocyte pool. There was also 15.4 (+ or -) 1.9 % of B lymphocytes found in the total bone marrow lymphocyte pool. There was a remarkable 74.6 (+ or -) 2.4 % of the total pool that had no special marks to identify it as a specific type of lymphocyte. The findings can not be explained nor were they tampered with.

There is more to repairing bones than just vitamin D and calcium. To specifically answer this question, yes there are vitamins, vitamin D and vitamin K.

Vitamin D helps with calcium absorption in the gut. Without it the calcium won't get into your body. However just because calcium gets into your body, that doesn't mean it's going to the right place. Many people actually loose the calcium in their bones, while calcium deposits in places it's not supposed to be such as arteries.

Vitamin K is essential for carrying and directing calcium to where it is supposed to go. Therefore vitamin D and vitamin K should be taken together.

To get more specific, Vitamin K is is responsible for the carboxylation of Matrix Gla Protein, which is a strong inhibitor of arterial calcification. Matrix Gla protein is responsible for putting calcium in the bone and keeping it out of the arterial wall. Without vitamin k calcium will be more likely to stay in the blood and deposit on atrial walls.

Vitamin K is high in green leafy vegetables, is also produced by good gut bacteria (which many people don't have) in vitamin k supplements and a very, very few vitamin D supplements also have vitamin k in them.

btw: this problem is due to low vitamin k. If you get your vitamin D from supplements or sunlight it won't matter!

a tube of ky jelly, a butt plug, and an inflatable doll. they were out at sea for months at a time what did you expect?

The urinary system and the circulatory system work together when the chemicals go through the circulatory systems. The chemicals eventually go throw the circulatory system and reaches the urinary system and helps process of decomposing.

There are several reasons why it is so easily broken. First of all, it is the last bone in the body to fully form. Secondly it is the only bone that attaches a very movable joint (shoulder) to a more stable axial attachment to the sternum. So it is vulnerable to major impact as a result of its precarious position attaching the arm to the axial skeleton. In other words, it is the weakest bone of the arm complex, and at the same time most vulnerable to injury. It has the reputation of being the most frequently broken bone in the body.

yes only the lower jaw moves
