Skeletal System

15-16 is the legal age ,but if you dont want to wait you should ask around and call diffrent shops.because it really depends what state ,but some shops do pierce anything as long as theres a person 18 years or older with you.plus it doesnt even have to be a parent.some even just need a consent form for your parent/guardian to fill out.

The ribs protect the lungs, heart, intestines, most of your valuable organs, livers and such.

If you've been coughing quite a bit, it's likely a sore diaphragm. This is the muscle which pulls air into and forces air out of your lungs. Reflexive coughing causes the diaphragm to contract more quickly than during normal breathing, and, just as with any muscle, can cause soreness and tenderness.

The two types of marrow are : 

● Red Marrow

● Yellow Marrow

● The function of the red bone marrow is to produce new blood cells

● The yellow marrow stores fat that can be served as an energy reserve. √ :D :P B-)

That would be the Tibia, the thinner one next to it is the Fibula. The Femur bone is the upper part on the thigh.

The hip bone (innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three bones; ilium, ischium, and pubis.

There are three, the hammer, anvil and stirrup who vibrate on the cochlea.

the skeletal system give blood from the heart to the circulatory system to keep homeostasis

Bone and cartilage are both types of connective tissues found in the body that provide structure and support. They share a similar extracellular matrix, which helps maintain their shape and function. Additionally, both tissues play crucial roles in the skeletal system, with cartilage serving as a flexible support structure and bone providing strength and rigidity. However, they differ significantly in composition, density, and blood supply.

The lumbar vertebrae is a long bone

To join all of the bones as one, while our shape would not radically change, we would not be able to move. We would require constant care. Our circulation would suffer and our life expectancy would plummet.

bone char which is the bones of cows is used to whiten sugar.

Pad and protect bones, abdominal muscles protect internal organs and reinforce and cushion joints

The process of turning into bone is called ossification.

Your clavicle (collarbone) in your shoulder is the most commonly fractured bone, usually caused by landing on an outstretched arm and pushing your shoulder back or (as in my current case) a direct fall or direct trauma.

its muscles and joints

The three bones in your ear (the Auditory Ossicle) are the smallest in the human body. They are the malleus, the incus, and the stapes. Commonly called the hammer, the anvil and the stirrup respectively.

Rheumatoid arthritis is a result of a form of autoimmune disease. The immune system disorder leaves your body unable to determine clearly what is your own tissue and what could be an invader. It mistakenly targets the tissues in the joints as foreign substances and causes inflammation in the area to try to "kill" what it has incorrectly determined is a pathogen. This results in painful swelling that can eventually result in erosion of synovial (joint lining) tissue and bone tissue in the joint and eventually in joint deformity and stiffness. People can become nearly immobile due to the pain of movement. It can also cause inflammation of other tissues, and even systemic (whole body) flare ups with fevers and fatigue. It is a chronic long term disease. Drugs that suppress the immune system are often prescribed to treat it, leaving those with the disorder more susceptible to infectious diseases.

More information:

The synovial membrane becomes severely inflamed. Usually thin and delicate, the synovium becomes thick and stiff, with numerous infoldings on its surface.

Omega 3 fish oils in the diet can help with the inflammation. Other aids in treating the disease include weight loss for less stress on the joints. In some people, food allergies can trigger the red hot swollen joints. When the immune system is suppressed, avoid being in crowds. Minor infections, such as a cold can also trigger the outbreak of arthritis (inflammation of a joint). Keep mobile, walk or swim, or go aqua jogging. Joint protection from even minor injury is a must, also avoid tripping up curbs, falling over stones or stumbling on rugs in the home, etc. Make sure you slowly build up to exercise when your physician says it is okay to do so.

thigh bone

finger bone

It is the shoulder blade. It connects the arm bone to the collar bone. It connects to many shoulder muscles to move your arms and shoulders.

In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.

People have been telling me for years that exercise releases endorphins and hormones into the blood stream and would help my anger, anxiety, depression, etc. But me, I am stubborn I wouldn't do it, until today. The whole idea is to increase your heart rate and your breathing rate. This will cause the brain to release these feel good hormones into the blood stream. Give it a try. If you can do 10 sit ups without breathing hard, up it to 15. If you can walk around the block without breathing hard, go around twice. See how many times you have to bend from the waist and slap the floor as if it were someone you were mad at, before your heart rate increases and you feel better. Take it from someone who found out for themselves - exercise can cure just about anything that ails you and more importantly it empowers you! Good luck!

No, the fingernail is distal to the elbow. Imagine a body standing with arms and legs spread out, like Da Vinci's Vitruvian Man. To determine if a part is distal or proximal to another part, look to see if it is closer or farther from the center of the body relative to the body part you are comparing it to. The fingernail is farther from the center of the body than the elbow, so it is distal to the elbow. In contrast the shoulder is closer to the center of the body, so it is proximal to the elbow. Using the same reasoning, the elbow is distal to the shoulder. When you're comfortable with those distinctions, you can start thinking about other terms like ventral, dorsal, caudal, saggital, coronal, etc.

It is the thigh bone. It is the longest bone in the body.

Fractures and/or breaks. As you can tell just from being in school, many people have broken or fractured a bone at least once.
