PPT-Chapter 6: Skeletal Tissues:

Bones Ligaments Cartilage FUNCTIONS OF skeletal tissues SUPPORT B o nes form the FRAMEWORK of the body and contribute to the shape alignment and positioning of body parts. System. No . bones about it!. 5 . Functions of the Skeletal System…. Provides shape . and supports . for . body. Allows for movement. Protects internal organs. Stores materials (calcium and lipids). Know the structure and functions of the skeletal system. Know the roles that the skeletal system performs. Functions of the skeletal system. With a partner discuss the functions of your skeleton. How many of the 5 functions can you identify?. 1. Gives shape and support. 2. Protects internal organs. (Skull, Rib-cage). 3. Muscles attach to bones.. 4. Blood cells are formed in bone marrow. . 5. Calcium and Phosphorous storage. . http://kidshealth.org/kid/htbw/SSmovie.html. 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. 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?. Quietly find your seat and get ready for class. Hand in skeleton projects below on chair. Fun Questions. How many bones are in the human body?. Have you ever broken a bone?. What is the largest bone in your body?. ~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?. 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.

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 . What is the process of bone formation?. What are the structures of the long bones?. What are the structures of the skeletal system? . The skeletal system. Compromises the bony framework of the body.. Degeneration Figure Legend:Figure 1Skeletal muscleDegeneration in a male Harlan SpragueDawley rat from a subchronic study. A central myofiber is swollen and hypereosinophilic(arrows), and a fragmented All of the bones in your body make up the skeletal system. There are 206 bones in an adult’s human body (at birth, you had more than 300 bones!). A . skeleton. is a framework of living bones that supports your body. . Human Skeletal System. Functions. Framework and support. Protection. Storage of minerals such as calcium. Movement. Production of blood cells (bone marrow). Human Skeletal System. The . axial. skeleton is the central part of the skeleton used to protect vital organs such as the brain, heart, and lungs.. . Tissues have two interacting components:. Cells .. . Extracellular matrix (ECM).which is consist of many kinds of macromolecules.. The (ECM) function :. Supports the cells and the fluids that transports nutrients to the cells ..
