what is the Skeletal System?

The Skeletal System acts as the structural support and anchor for the body. It supports any movement throughout the body. There are two hundred six bones in the adult human body, however the skeleton bones are split into two parts; the axial skeleton which protects the organs from harm (ex. ribs, skull, and the hips), alongside the appendicular skeleton, which acts as an anchor for the muscles to cling onto (ex. femur, fingers, and the knees). The skeletal bones are considered the main warehouse for the minerals, while the bone marrow is the main source for blood production to flow. The bone marrow is great source for stem cells because it is where the red and white blood cells are produced.

Diseases

A few common diseases of the skeletal system consist of Fibrous Dysplasia, Rhuemitoid Arthritus, Oseoporosis, and Paget's Disease, and numorous more. Depending on the disease, it could be either hereditary which are mainly passed down thru the family or genetic disease which is often thru the skeleton chromosones.

fibrous Dysplasia

Fibrous Dysplasia (FD) is a chronic disease that causes scar like tissue to take place of the bone, ultimately weakening it and causing for a higher risk of breakage. FD can affect only one bone (monostotic) or multiple bones (polystotic) in the body. This disease can be on its own or come as a symptom to a condition known as McCune-Albright Syndrome.

Formation of fd

Fibrous Dysplasia is caused by a genetic mutation in early develeopment in the womb. This means that FD will not spread to any other bones, and it will stay in the bone where the gene has been mutated. This also means that anyone can have this chronic illness. Lets learn about some of the symptoms of Fibrous dysplasia

Symptoms

Some of the symptoms for FD include but are not limited to; bone pain, misshapened bones, bowing or curving of the bones, frequent fractures, and shortening of the bones.

tests

Now, you might be wondering, "How can I get tested?" and if you're not, I am still going to inmform you how to get tested anyway! The diagnostic tests needed to get diagnosed are X-Rays, and CT. The laboratory tests needed are a urinalysis, phosphorus, and enzyme levels. However, since FD can take place in the skull, hearing and vision tests are very critical to test for.

Treatment

Unfortunately, Fibrous Dysplasia is a chronic condition, meaning there is no official cure for FD diagnosis. Since it is a genetic mutation, theres nothing the mother can do to prevent her child from having it either. However, there are treatments to help manage the chronic pain, the abnormal impairments, along with most other symptoms caused by FD.

Conclusion

Today, we have learned about the Skeletal System and some of the diseases that can happen with this specific system. The disease I chose to focus on was Fibrous Dysplasia. This disease is caused by a genetic mutation during early development in the womb. There are a variety pf tests that can be done to diagnose fibrous dysplasia, including but not limited to; x-ray, CT, Urinalysis, and phosphorus. While this disease may have no cure, it ca be treated for pain, and some people may not have any symptoms at all.
