    Study Notes

    Locating Body Organs and Structures

    • Visualization is key to understanding body structures and their relationships. Imagine illustrations overlaying on patient anatomy.
    • Topography and landmarks utilize body features (elbows, wrists, clavicles) as reference points.
    • Palpation involves touching the patient to detect irregularities.
    • Auscultation uses a stethoscope to listen to the patient (breathing, heartbeat, bowel sounds).
    • Utilize visual aids to overlay illustrations over the body for a better understanding of internal structures.
    • Use physical features such as joints, bones, and lines to identify and locate anatomical locations.

    Musculoskeletal System

    • Functions: Shape, protection of organs, and movement.
    • Skeletal system: Supports, protects, stores minerals, and facilitates movement via muscle attachments.
    • Tendons connect muscle to bone.
