Skeletomuscular System

By: Jessica, Cassidy, Anais, and Kyle

Overall Function The skeletomuscular systems function is to act as the framework for tissues and organs

to attach themselves to. The system acts as a protective structure for vital organs. Examples of this are the brain being protected by the skull and the lungs being protected

by the rib cage.

There are 206 bones in the body. The bones preform 5 main functions

Provide support for the body — The skeletal system provides structural support for the entire body. Individual bones or groups of bones provide a framework for the

attachment of soft tissues and organs. Store minerals and lipids — Calcium is the most important mineral in the body. The

calcium salts of bone are a valuable mineral reserve that maintains normal concentrations of calcium and phosphate ions in body fluids. The bones of the skeleton

also store energy reserves as lipids in areas filled with yellow marrow. Produce blood cells — Red blood cells, white blood cells, and other blood elements are

produced in the red marrow, which fills the internal cavities of many bones. Protects body organs — Many soft tissues and organs are surrounded by skeletal

elements. For example, the rib cage protects the heart and lungs, the vertebrae protect the spinal cord, and the pelvis protects the delicate reproductive organs.

Provide leverage and movement — Many bones function as levers that can change the magnitude and direction of the forces generated by muscles.

Organs and Major Structures• There are three types of muscle tissue visceral, cardiac,

and skeletal.• Visceral/Smooth muscle is found inside the stomach,

intestines, and blood tissue. Visceral muscle makes organs contract to move substances through the organ.

• Cardiac muscle found only in the heart is responsible for pumping blood throughout the body.

• Skeletal muscle is the only voluntary muscle tissue in the human body that’s controlled consciously. The function is to contract to move parts of the body closer to the bone.

Diseases

• Osteoarthritis • Rheumatoid Arthritis

• Osteomalacia

Treatment Osteoarthritis Treatment for Osteoarthritis

includes…• Acetaminophen

it can relieve pain, but it doesn't reduce inflammation. It has been shown to be effective for people with osteoarthritis who have mild

to moderate pain.• Nonsteroidal anti-inflammatory

drugsIt may reduce inflammation and

relieve pain.• Therapy

A physical therapist can work with you to create an individualized

exercise program that will strengthen the muscles around

your joint, increase your range of motion and reduce pain.

Rheumatoid Arthritis Treatment for Rheumatoid Arthritis includes…

• Steroids Corticosteroid medications, such

as prednisone, reduce inflammation and pain and slow

joint damage.• Disease-modifying

antirheumatic drugsThese drugs can slow the progression of rheumatoid

arthritis and save the joints and other tissues from permanent

damage.

OsteomalaciaTreatments for

Osteomalacia includes…• vitamin D supplements

Helps improve the signs and symptoms of osteomalacia.

Research/ Technology

Laboratory Tests

• Laboratory tests are often helpful in making the diagnosis of a musculoskeletal disorder.Nerve and Muscle Tests

• Nerve conduction studies help determine whether the nerves

supplying the muscles are functioning normally.

X-Rays• X-rays are most valuable for detecting abnormalities in bone

and are taken to evaluate painful, deformed, or suspected abnormal

areas of bone.
