PPT-Skeletal System

4 Functions of the Skeletal System 1 Supports the body The backbone is the main support center for the upper body It holds your head up and protects your spinal cord 2 Protects internal organs. Support: bones help support and provide shape to the body. Protection: provides protection to internal organs. Mineral storage: calcium and phosphorus make bones strong and help with oxygen.

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 .
