6: Bones and Skeletal Tissues Objectives Skeletal Cartilages 1. Describe the functional properties of the three types of cartilage tissue. 2. Locate the major cartilages of the adult skeleton. 3. Explain how cartilage grows. Classification of Bones 4. Name the major regions of the skeleton and describe their relative functions. 5. Compare and contrast the structure of the four bone classes and provide examples of each class. Functions of Bones 6. List and describe five important functions

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE

Introduction: Weight loss‚ in the context of medicine‚ health‚ or physical fitness‚ is a reduction of the total body mass‚ due to a mean loss of fluid‚ body fat oradipose tissue and/or lean mass‚ namely bone mineral deposits‚ muscle‚ tendon‚ and other connective tissue. Weight loss is one of today’s most trendy obsessions among individuals. Weight loss can have positive and negative consequence on an individual. It can occur unintentionally due to an underlying

of vascular tissues‚ together they for vascular bundles and are responsible for the survival of the plant. Xylem flows only from bottom up to the top and Phloem flows both ways. Phloem is the innermost layer of the bark in most trees. Outer Phloem is dead cells and inner Phloem is living cells‚ when the primary Xylem cells become dead‚ losing their conducting function and forming a hard skeleton that serves support to the plant. Xylem is part of a vascular tissue. The vascular tissue transports fluids

Thousands of donated heart valves can replace damaged ones‚ allowing the heart to function well again; musculoskeletal tissue replaces bone‚ tendons and ligaments lost to cancer‚ severe trauma‚ degenerative joint disease‚ arthritis‚ and other conditions. Also‚ skin can save the lives of burn victims. "Bidding for bodies" (Dwyer) or advancing scientific research?

SCIENTIFIC INVESMENT WHAT IS MEAN BY SCIENTIFIC INVESMENT? Can investment analysis of common stocks be more effective by relying on so-called scientific or quantitative methods or on subjective intuitive methods? The quantitative method relieves the financial analyst from making the simpler investment "decision rules" by placing them in tables‚ charts‚ and computer programs. Evidence suggests that an intelligent use of quantitative techniques‚ strengthened by competent judgment‚ may offer fascinating
