    1198 Chapter 38 | The Musculoskeletal System Decalcification of Bones Question: What effect does the removal of calcium and collagen have on bone structure? Background: Conduct a literature search on the role of calcium and collagen in maintaining bone structure. Conduct a literature search on diseases in which bone structure is compromised. Hypothesis: Develop a hypothesis that states predictions of the flexibility, strength, and mass of bones that have had the calcium and collagen components removed. Develop a hypothesis regarding the attempt to add calcium back to decalcified bones. Test the hypothesis: Test the prediction by removing calcium from chicken bones by placing them in a jar of vinegar for seven days. Test the hypothesis regarding adding calcium back to decalcified bone by placing the decalcified chicken bones into a jar of water with calcium supplements added. Test the prediction by denaturing the collagen from the bones by baking them at 250°C for three hours. Analyze the data: Create a table showing the changes in bone flexibility, strength, and mass in the three different environments. Report the results: Under which conditions was the bone most flexible? Under which conditions was the bone the strongest? Draw a conclusion: Did the results support or refute the hypothesis? How do the results observed in this experiment correspond to diseases that destroy bone tissue? 38.3 | Joints and Skeletal Movement By the end of this section, you will be able to do the following: • Classify the different types of joints on the basis of structure • Explain the role of joints in skeletal movement The point at which two or more bones meet is called a joint, or articulation.

  • RADIOULNAR JOINTS the Radius and Ulna Articulate by –
    RADIOULNAR JOINTS The radius and ulna articulate by – • Synovial 1. Superior radioulnar joint 2. Inferior radioulnar joint • Non synovial Middle radioulnar union Superior Radioulnar Joint This articulation is a trochoid or pivot-joint between • the circumference of the head of the radius • ring formed by the radial notch of the ulna and the annular ligament. The Annular Ligament (orbicular ligament) This ligament is a strong band of fibers, which encircles the head of the radius, and retains it in contact with the radial notch of the ulna. It forms about four-fifths of the osseo- fibrous ring, and is attached to the anterior and posterior margins of the radial notch a few of its lower fibers are continued around below the cavity and form at this level a complete fibrous ring. Its upper border blends with the capsule of elbow joint while from its lower border a thin loose synovial membrane passes to be attached to the neck of the radius The superficial surface of the annular ligament is strengthened by the radial collateral ligament of the elbow, and affords origin to part of the Supinator. Its deep surface is smooth, and lined by synovial membrane, which is continuous with that of the elbow-joint. Quadrate ligament A thickened band which extends from the inferior border of the annular ligament below the radial notch to the neck of the radius is known as the quadrate ligament. Movements The movements allowed in this articulation are limited to rotatory movements of the head of the radius within the ring formed by the annular ligament and the radial notch of the ulna • rotation forward being called pronation • rotation backward, supination Middle Radioulnar Union The shafts of the radius and ulna are connected by Oblique Cord and Interosseous Membrane The Oblique Cord (oblique ligament) The oblique cord is a small, flattened band, extending downward and laterally, from the lateral side of the ulnar tuberosity to the radius a little below the radial tuberosity.

  • You Have 24 Vertebrae in Your Spinal Column. Two Are Special Enough to Be Individually Named
    You have 24 vertebrae in your spinal column. Two are special enough to be individually named. Your atlas (C01) and axis (C02) are very important vertebrae. Without them, head and neck movement would be impossible. Let’s take a look! The atlas and axis are the most superior bones in the cervical vertebrae. The atlas is the top-most vertebra, sitting just below the skull. The axis is below it. Together, the atlas and axis support the skull, facilitate head and neck movement, and protect the spinal cord. (Think of the atlas and axis as best buds for life. You will never find one without the other.) www.visiblebody.com There are many types of vertebral joints, but the atlas and axis form the only craniovertebral joints in the human body. A craniovertebral joint is a joint that permits movement between the cervical vertebrae and the neurocranium. The atlanto-occipital joint (pictured) connects the atlas to the occipital bone. It flexes the neck, allowing you to nod your head. The atlanto-axial joint connects the axis to the atlas. It permits rotational movement of the head. www.visiblebody.com The atlanto-axial joint is a compound synovial joint. This pivot joint allows for rotation of the head and neck. Watch this joint in action! A pivot joint is made by the end of one articulating bone rotating in a ring formed by another bone and its ligaments. www.visiblebody.com The atlas and axis are part of the seven cervical vertebrae. These vertebrae have a few unique features: They are the smallest of the vertebrae.

  • Current Perspectives in Conventional and Advanced Imaging of the Distal Radioulnar Joint Dysfunction: Review for the Musculoskeletal Radiologist
    Skeletal Radiology (2019) 48:331–348 https://doi.org/10.1007/s00256-018-3042-1 REVIEW ARTICLE Current perspectives in conventional and advanced imaging of the distal radioulnar joint dysfunction: review for the musculoskeletal radiologist Aishwarya Gulati1 & Vibhor Wadhwa2 & Oganes Ashikyan3 & Luis Cerezal4 & Avneesh Chhabra3,5,6 Received: 25 December 2017 /Revised: 27 July 2018 /Accepted: 1 August 2018 /Published online: 1 September 2018 # ISS 2018 Abstract Distal radioulnar joint (DRUJ) dysfunction is a common cause of ulnar sided wrist pain. Physical examination yields only subtle clues towards the underlying etiology. Thus, imaging is commonly obtained towards an improved characterization of DRUJ pathology, especially multimodality imaging, which is frequently resorted to arrive at an accurate diagnosis. With increasing use of advanced MRI and CT techniques, DRUJ imaging has become an important part of a musculoskeletal radiologist’s practice. This article discusses the normal anatomy and biomechanics of the DRUJ, illustrates common clinical abnormalities, and provides a comprehensive overview of the imaging evaluation with an insight into the role of advanced cross-sectional modalities in this domain.

  • Module Two: Anatomy of the Athlete
    Module Two: Anatomy of the Athlete INTRODUCTION The Level One course provided you with basic information about the skeletal and muscular systems of the body. This module studies these systems in more depth, applies this knowledge to the analysis of human movement, and looks at the application of analysis results to the development of conditioning programmes for athletes. Upon completion of this module, you will be able to: EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE SKELETAL SYSTEM UNDERSTAND THE STRUCTURE OF JOINTS AND THE MOVEMENTS POSSIBLE AT SYNOVIAL JOINTS EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE MUSCULAR SYSTEM EXPLAIN MUSCLE ACTION IN THE HUMAN BODY APPLY YOUR KNOWLEDGE OF THE SKELETAL AND MUSCULAR SYSTEMS TO ANALYSE MUSCLE ACTION EXPLAIN THE STRUCTURE AND FUNCTIONS OF THE SKELETAL SYSTEM THE SKELETAL SYSTEM The framework of the human body is made up of just over 200 bones, which vary considerably in size and shape. Bones are often thought of as dry, inert structures, similar to a bone which has been dug up in the garden by the neighbour’s dog! However, bone is not a dead structure. It is made up of living bone tissue, which is a type of connective tissue, the hardest of all connective tissues found in the body. FUNCTIONS OF THE SKELETON The skeleton has five important functions in the body: 1. Protection The bones protect internal organs by forming strong protective enclosures, e.g. skull, ribs, spine. 2. Support The skeleton gives rigidity to the body. Without the support of the skeleton, we would be shapeless lumps. 3.
