The ability to recognize a specific injury to musculoskeletal and nerve structures and understand those mechanical factors that produce injuries or trauma is essential for the athletic trainer.11 Trauma is defined as a physical injury or wound that is produced by an external or internal force.3 This chapter provides the foundation for the identification,understanding,and management of Mechanisms and Characteristics of Musculoskeletal and The ability to recognize a specific injury to musculoskeletal and nerve structures and understand those mechanical factors that produce injuries or trauma is essential for the athletic trainer.11 Trauma is defined as a physical injury or wound that is produced by an external or internal force.3 This chapter provides the foundation for the identification,understanding,and management of Mechanical properties of cortical bone and their The growing incidence of skeletal fractures poses a significant challenge to ageing societies.Since a major part of physiological loading in the lower limbs is carried by cortical bone,it would be desirable to better understand the structure-mechanical property relationships and scale effects in this tissue.

Mechanical Properties of Ligament - Musculoskeletal Key

In Chap.2 we explored the architecture and composition of ligaments and tendons,non-calcified but nonetheless extremely tough skeletal tissues responsible for binding bones together,transmitting forces from muscles and constraining motion within normal limits.To briefly review,ligaments and tendons are composed of linearly arranged collagen molecules assembled in a hierarchal fashion into Mechanical Properties of Bone SpringerLinkIt is now time to bring these two aspects of skeletal tissue mechanics together to learn how strong bones are relative to the loads they must bear,and how the mechanical properties of bones depend on their structure.KeywordsMechanical Properties of Bone Musculoskeletal KeyThe mechanical properties of bones are governed by the same principles as those of manmade load-bearing structures.However,the ability of vertebrates to adapt their bone structure to the imposed loading,in terms of both the evolution of a genetic plan for the skeleton and the ability to acutely modify this plan by cellular activity,results in a structure that is highly complex and,when healthy,very effective.
