Skeletal System

A normal rib break is usually but not always accompanied by bruising on the chest. The chest wall however has no changes in shape except for swelling or bruising. Pressing on the outside of the chest at the wound site hurts, and so does inhaling deeply. For a standard break like this, there really isn't anything you can do except to treat for pain. It also takes around 2 weeks to a month to heal -- sometimes more.

If your breathing is actually impeded, if you cough up blood, or if there is a depressed area on the chest at the wound site (like a dent), seek medical help instantly.

The zone of Calcified Cartilage

The tail bone in humans is the vestigal coccyx bone, which extends from the end of the pelvic girdle in a straight line with the spine.

Diaphragm

there are seven pairs of ribs that are comlpetely attached bonetobone and there are three pairs that are attached wiht cartilage. the last remaining"floating" ribs are not attached. All the ribs are atached to the spine.

Because they contain collagen, which gives some flexibility

The humerus bone. =)

Frontal Sinuses.....

the temporal bone is the sleeping bone, they say it like that because you sleep on it. so when you sleep you will be able to localise it

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.

Sutures

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

gliding

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
