  1. Human Anatomy Chapter 2 Sport Books Publisher

  2. Table of Contents • Introduction • Terms and Concepts Worth Knowing • Anatomical Position • Directional Terms • Planes of the Body • The Musculoskeletal System • Bones • Joints • Muscles Sport Books Publisher

  3. Introduction: What is the Structure of My Body? • Human Anatomy: The study of the structures that make up the human body and how those structures relate to each other. • Structure determines function: The structures of the human body are well-designed for efficient movement. Sport Books Publisher

  4. Terms and Concepts Worth Knowing Sport Books Publisher

  5. Anatomical Position Sport Books Publisher

  6. Legs straight Heels, feet and great toes parallel to each other The starting reference point for describing the human body It is universally accepted It is used in all anatomical descriptions Palms facing forward and the thumbs outward • Description • Standing erect • Facing forward • Arms hanging at the sides Sport Books Publisher

  7. Directional Terms Sport Books Publisher

  8. Reminder: All directional terms are based on the assumption that the body is in the anatomical position. Sport Books Publisher

  9. Lateral-Medial Lateral – Away from the midline of the body Midline Lateral Medial – Medial – Toward the midline – E.g., Your ears are lateral to your cheeks and your cheeks are medial to your ears Sport Books Publisher

  10. Distal-Proximal • Distal – Further from some specified region • Proximal – Closer to some specified region • E.g., With respect to the trunk, the hands are distal to the arms and the arms are proximal to the hands. • E.g., With respect to nerves and blood vessels, proximal also means "toward the origin" and distal means "away from the origin" • E.g., The colon is the distal portion and stomach is the proximal portion of the digestive tract Thigh is proximal to the leg Leg is distal to the thigh Leg is proximal to the foot Foot is distal to the leg Sport Books Publisher

  11. Anterior Skeleton Posterior Skeleton • Anterior-Posterior • Anterior – In front of or front of your body – Posterior – Behind or back of your body • – E.g., Your lips are anterior • to your teeth and your • teeth are posterior to your • lips – E.g., In the anatomical position, your palms are facing anteriorly Sport Books Publisher

  12. The collar bone is superior to the rib cage • Superior-Inferior • Superior – Above • Inferior – Below The hip bone is inferior to the rib cage – E.g., Your lips are superior to your chin and your chin is inferior to your lips Sport Books Publisher

  13. Supine Lying on the back E.g., Performing a bench press • Prone • Lying face down • E.g., Preparing to • perform a push-up Sport Books Publisher

  14. Planes of the Body Sport Books Publisher

  15. Planes • Imaginary flat surfaces that divide the human body • They are used to: • divide the body for further identification of particular areas • describe different movements or actions • Always refer to the body in the anatomical position Sport Books Publisher

  16. Median Plane • Median plane or midsagittal plane • A vertical plane that bisects the body into equal right and left halves –Sagittal plane is any plane parallel to the median plane Sport Books Publisher

  17. Coronal Plane • Coronal plane or frontal plane • A vertical plane that bisects the body into front and back – It is at right angles to the median plane Sport Books Publisher

  18. Transverse Plane • Transverse plane or horizontal plane • A horizontal plane that bisects the body into top and bottom • It is at right angles to both the median and coronal planes Sport Books Publisher

  19. Center of gravity • The point at which the median, frontal, and transverse planes intersect Sport Books Publisher
