Role of muscle fiber types as it relates to different types of athletic performances. Histochemical . techniques for identification of muscle fiber types. The skeletal system is made up of organs called bones.. An adult human has 206 bones, but babies are born with 270 bones. Why?. The male and female skeleton have 1 major difference -what is it?. The female pelvis is wider and deeper. Why?. Sabrina Barner, Abbe Carlin, Amber Weigle. Neuromuscular Junctions. Communication link between nervous system and skeletal muscle fiber. Specialized intercellular connection. Each skeletal muscle fiber is controlled by a nerve cell. ~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?.

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 .
