Skeletal System

By: Brianna Navarro

What does the skeletal system do?

Provides the body with a rigid framework for support and protection.

Major Organs in the Skeletal System

Bones: Four Major types: Long bones, Short bones, Flat bones

Ligaments: anterior longitudinal ligament, interspinous ligaments, intervertebral,

Cartilage: elastic, fibrocartilage, hyaline

Joints: acromioclavicular joints, carpometacarpal joints, coracoclavicular

3 Different homeostatic imbalances

Bone Fractures:


How is it caused? Trauma: A fall, a motor vehicle accident, or a tackle during a football game can all result in bone fractures

What are the symptoms? Swelling, Pain, Bleeding/Bruising, Deformity

How is one treated? Cast immobilization, functional cast or brace


Arthritis:


How is it caused? Osteoarthritis causes cartilage to break down. Uric acid crystals, infections or underlying disease, such as psoriasis or lupus, can cause other types of arthritis.

What are the symptoms? The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age.


How is one treated? Treatments vary depending on the type of arthritis. The main goals of arthritis treatments are to reduce symptoms and improve quality of life.


Two of the most common forms of arthritis are osteoarthritis and rheumatoid arthritis.



Osteoporosis:

How is it caused? Disorder that weakens bones and makes them more likely to break

What are the symptoms? There are no symptoms in the early stages. People will have a bone fracture before learning they have the disease. Pain is almost anywhere in the spine and can be caused by fractures of the bones of the spine. There can be a loss of height over time. A stooped posture or kyphosis may develop.


How is one treated? Lifestyle changes, such as diet and exercise, taking calcium and vitamin D, using medicines.

This article was about researching and understanding skeletal muscle growth and development. The article also talked about how microarray analysis of gene expression and skeletal muscle-derived stem cells are advances that will have an influence on our understanding of muscle growth and development.
