What is the largest bone in your body?. WARM-UP. Answer the following questions to the best of your ability….. 1. How many bones are in the human body? . . Does that number ever change?. 2. Why do we have bones?. 3. Are bones alive?. Learning Objectives. Describe the . anatomy . and . physiology . of skeletal muscle. Role of muscle fiber types as it relates to different types of athletic performances. Histochemical . techniques for identification of muscle fiber types. ~What are the functions of the skeletal system?. ~What are some disorders of the skeletal system?. ~How are skeletal disorders treated?. ~How does the skeletal system relate to the body’s systems of support and movement?. The Skeletal System . Skeletal System – bones of the body, shields important organs, gives your body shape. Skull protects the brain / Ribs Protect your heart and lungs / Back bone protects your spinal cord. Provides shape and support.. Enables us to move.. Protects your internal organs.. Produces blood cells.. Stores minerals such as calcium and phosphorous.. Bone Formation and Growth. As a baby, most of your skeletal system is made up of cartilage..

Developmental and reproductive toxicology (DART) studies are required for new chemical entities going to market to ensure that there are not adverse developmental consequences associated with the chemical. These studies involve dosing a pregnant female animal (e.g. mouse, rat, rabbit) with the compound and evaluating the effect of the chemical on the offspring. This evaluation involves the parallel processes of histopathology and gross morphological evaluation wherein the most time-consuming component of DART studies is the performance of gross skeletal evaluation. Since the introduction of Thalidomide into the marketplace, close attention has been paid to the impact of chemicals on skeletal development and DART studies require the visualization of gross skeletal morphology for abnormalities. The current methodology for conducting skeletal evaluation involves digesting soft tissue using a strong base (potassium hydroxide) and staining the bone with alizarin and cartilage in some cases with .
