  • Module 2 : Anatomy – the Skeleton
    Module 2 : Anatomy – The Skeleton In this module you will learn: The functions of the skeletal system The types of bones in the human body The effects of exercise on your bones What happens to the bones as we get older When studying to become a fitness instructor or personal trainer, you will learn all about the anatomy of the human body. Studying the skeleton is one of the foundations of your trade, you will need to know how the body is structured, the names of each bone, types of bones, importance of bone and joint health, detail of the spine and different terms of movement. Without stating the obvious, each of your clients has their own skeleton and you must be fully aware of how this works. This is for many reasons; you are a teacher and must be fully aware of how to prevent injuries, avoid unnecessary stress on the bones and, if qualified, help the client prevent or heal bone and joint related conditions or medical problems. 2.1 Understanding the Skeletal System The skeleton is comprised of 206 different bones that provide 5 main functions: Support mechanism for muscle and tissue Protection for organs Movement with bones, muscles, and joints Storing minerals and blood cells Growth Skeletal System 2.2 Bones are Formed by Ossification Some bones (such as the flat bones of your skull) in the body are formed in a similar stage to connective tissue. The process is known as direct or intramembranous ossification. Other bones are made up of cartilaginous matter, this is developed from future bone in the embryo which then dissolves and is replaced with other bone cells.

    Cartilage Development and Maturation In Vitro and In Vivo Johnathan Ng Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences Columbia University 2017 © 2017 Johnathan Ng All rights reserved Abstract Cartilage Development and Maturation In Vitro and In Vivo Johnathan Ng The articular cartilage has a limited capacity to regenerate. Cartilage lesions often result in degeneration, leading to osteoarthritis. Current treatments are mostly palliative and reparative, and fail to restore cartilage function in the long term due to the replacement of hyaline cartilage with fibrocartilage. Although a stem-cell based approach towards regenerating the articular cartilage is attractive, cartilage generated from human mesenchymal stem cells (hMSCs) often lack the function, organization and stability of the native cartilage. Thus, there is a need to develop effective methods to engineer physiologic cartilage tissues from hMSCs in vitro and assess their outcomes in vivo. This dissertation focused on three coordinated aims: establish a simple in vivo model for studying the maturation of osteochondral tissues by showing that subcutaneous implantation in a mouse recapitulates native endochondral ossification (Aim 1), (ii) develop a robust method for engineering physiologic cartilage discs from self-assembling hMSCs (Aim 2), and (iii) improve the organization and stability of cartilage discs by implementing spatiotemporal control during induction in vitro (Aim 3). First, the usefulness of subcutaneous implantation in mice for studying the development and maintenance of osteochondral tissues in vivo was determined. By studying juvenile bovine osteochondral tissues, similarities in the profiles of endochondral ossification between the native and ectopic processes were observed.

  • Bones of the Skeletal System
    BIOLOGY 211: HUMAN ANATOMY & PHYSIOLOGY ********************************************************************************************************* BONES OF THE SKELETAL SYSTEM ********************************************************************************************************** Reference: Saladin, KS: Anatomy & Physiology, The Unity of Form and Function, 6th ed. (2012) or 7th ed. (2015) Please review Chapters 7 & 8 before beginning this lab. INTRODUCTION The skeletal system has a number of important functions in the human body. It is the framework around which the body is organized, it provides levers for muscles to pull against, and it surrounds and protects many soft organs. Equally important, bones serve as a "buffer" in which calcium and other ions can be deposited and withdrawn according to the changing needs of the body, and they are the site of almost all blood cell production. Contrary to our popular conceptions, bones are not rigid, inflexible structures: they are constantly changing, and can have a remarkable degree of flexibility before they break. The organs of the skeletal system are the bones and joints, and like all organs are composed of different types of tissue. Although we tend to classify them into "types" such as "long bones", "flat bones", etc., each is in fact unique and ideally suited to its particular location and function. We classify bones as belonging to either: a) the axial skeleton (head and trunk) b) the appendicular skeleton (arms and legs), However, you should always bear in mind that the entire skeletal system functions as a unit. If you look at any bone, you will see that it is rarely flat or smooth. Bones have a variety of bumps, grooves, holes, etc. which allow them to serve their specific functions.

  • Bone Cartilage Dense Fibrous CT (Tendons & Nonelastic Ligaments) Dense Elastic CT (Elastic Ligaments)
    Chapter 6 Content Review Questions 1-8 1. The skeletal system consists of what connective tissues? Bone Cartilage Dense fibrous CT (tendons & nonelastic ligaments) Dense elastic CT (elastic ligaments) List the functions of these tissues. Bone: supports the body, protects internal organs, provides levers on which muscles act, store minerals, and produce blood cells. Cartilage provides a model for bone formation and growth, provides a smooth cushion between adjacent bones, and provides firm, flexible support. Tendons attach muscles to bones and ligaments attach bone to bone. 2. Name the major types of fibers and molecules found in the extracellular matrix of the skeletal system. Collagen Proteoglycans Hydroxyapatite Water Minerals How do they contribute to the functions of tendons, ligaments, cartilage and bones? The collagen fibers of tendons and ligaments make these structures very tough, like ropes or cables. Collagen makes cartilage tough, whereas the water-filled proteoglycans make it smooth and resistant. As a result, cartilage is relatively rigid, but springs back to its original shape if it is bent or slightly compressed, and it is an excellent shock absorber. The extracellular matrix of bone contains collagen and minerals, including calcium and phosphate. Collagen is a tough, ropelike protein, which lends flexible strength to the bone. The mineral component gives the bone compression (weight-bearing) strength. Most of the mineral in the bone is in the form of hydroxyapatite. 3. Define the terms diaphysis, epiphysis, epiphyseal plate, medullary cavity, articular cartilage, periosteum, and endosteum. Diaphysis – the central shaft of a long bone. Epiphysis – the ends of a long bone. Epiphyseal plate – the site of growth in bone length, found between each epiphysis and diaphysis of a long bone and composed of cartilage.

The craniofacial area is prone to trauma and pathologies that often result in large bone damage, these leading to both aesthetic and functional complications for patients. The “gold standard” for treating these large defects is autologous bone grafting, which has some drawbacks including the requirement for a second surgical site with quantity of bone limitations, pain and other surgical complications. Indeed, tissue engineering combining a biomaterial with the appropriate cells and molecules of interest would allow a new therapeutic approach to treat large bone defects while avoiding complications associated with a second surgical site. This review first outlines the current knowledge of bone remodeling and the different signaling pathways involved seeking to improve our understanding of the roles of each to be able to stimulate or inhibit them.
