I) Bones: An Overview STUDY QUESTIONS List the parts of the Skeletal System and **Define the Axial and Appendicular Subdivisions. A. Parts of Skeletal System Bones (skeleton) Joints Cartilages Ligaments B. Subdivisions Define * Axial * Appendicular
C. Functions of Bones Explain *Support: *Protect: * Muscles: *Store: *Blood cell: D. Classification of Bones1. Structural Types Compact bone Spongy bone STUDY QUESTIONList and explain the Bone functions. STUDY QUESTION What are the two structural types of Bone and how are they different?
2. * Types by Shape ** List and Explain the Shape Types of Bones. Figure 5.1
D. Structure of a Long Bone 1. * Diaphysis- explain2. *Epiphysis- explain 3. Periosteum4. *Arteries5. *Articular cartilage: explain6. Epiphyseal plate = 7. Epiphyseal line = Study Question Identify and explain the anatomical areas of a long bone.
Anatomy of a Long Bone … 8. * Medullary cavity: define *Location:*Types Marrow: define E. Bone Formation, Growth, and Remodeling1. Growth & Formation: a. Dense connective plates, start asi) Specific types of bones: ?ii) Connective Tissue begins to be: iii) Eventually the bone replaces all membrane iv) In adult: The bone has Sutures:
E. Bone Formation, Growth, and Remodeling … b. Cartilage Models : i ) Specific Types of bones: ?ii) Bones start out as Cartilage Models in fetusiii) Bone replaces cartilage: iii) Then only Epiphyseal Plates are left: iv) Then bone replaces plates and get Epiphyseal Line: Bone remodeling: give functions of cells belowa. Osteocytesb. *Osteoclastsc. *Osteo blasts STUDY QUESTION Summarize the events of bone remodeling throughout life.
