Skeletal System

By: Sydney Archibald and Shelbie Rhodes

What is the function of the Skeletal System?

The function is to support, movement, protection, blood cell production, calcium storage and endocrine regulation

What are the roles of bones, ligaments, muscles, tendons and nerves in human movement?

Bones - for support, the bones provide a framework fot the attachment of muscles and other tissues. For protection, the bonest such as the skull and rib cage protect eternal organs from injury. For movement, the bones enable body movements by acting as a levers and points of attachment for muscles.

Ligaments - there are 3 types of ligaments in the human body. The most common form of ligament is the tought, fibrous tissue that connects one bone to another cone ofrming a joint. The ligaments provide joint stability. Their primary function is to prevent movement that might damage a joint.

Muscules - the main function of muscles is movement. Muscles are the only tssue in the body that has the ability to contract and therefore move the other parts of the body.

Tendons - the function of tendons is to connect muscle tissues to bones.

Nerves - nerves conduct impulses between your brain and receptors. The role of nerves, in particular, motor neurones, is that they transmit the instructions to move the body or part of the body as the brain says to.

What are 2 major disorders?

Bursitis - The bursa are specialized sacs of fluid found around our joints. They provide cushioning between the joints and nearby muscle, tendon and ligaments. The well-known condition of 'water on the knee' is an example of prepatellar bursitis. This condition causes pain, swelling and mild redness. Treatment includes avoiding pressure on the area, OTC medications such as ibuprofen and rest.

Leukemia - White blood cells are produced in part by the bone marrow. A variety of blood cancers are generally termed leukemia. The onset is generally insidious and until a critical mass of abnormal cells occurs, most people are without symptoms. Early warning signs include: bone pain, excess fatigue, easy bruising, night sweats, unexplained weight loss and bleeding gums.
