    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.
    • Ligaments connect bone to bone.
    • Skeleton Divisions:
      • Axial skeleton: Skull, spine, ribs, and sternum (colored white in the image).
      • Appendicular skeleton: Shoulders, upper extremities, pelvis, and lower extremities (colored red in the image).
      • Provides shape, protects vital organs, and enables body movement.

    Skull

    • Cranium: Top, back, and sides of the head.
    • Face: Front of the head.
    • Bones:
      • Frontal: Forehead.
      • Temporal: Side of the head, near ears.
      • Occipital: Base of the skull.
      • Parietal (Left & Right): Sides of the head.
      • Mandible: Lower jaw (only movable bone).
      • Maxilla: Upper jaw.
      • Nasal: Nose.
      • Orbits: Eye sockets.
      • Zygomatic: Cheekbones.
      • Large top, back, and sides of the head.
      • Front portion of the head.

    Spinal Column

    • Vertebrae: 33 bones forming the spinal column.
    • Spinal cord runs down the center of the vertebrae.
    • Regions:
      • Cervical Spine (7 vertebrae): Neck.
      • Thoracic Spine (12 vertebrae): Upper and middle back.
      • Lumbar Spine (5 vertebrae): Lower back.
      • Sacral: 5 fused vertebrae at the base of the spine.
      • Coccyx: 4 fused vertebrae (tailbone).

    Chest Area

    • Sternum: Breastbone, connecting to ribs.
      • Manubrium: Top section of the sternum.
      • Sternal Notch: Top of the manubrium.
      • Body of Sternum: Middle section, used for CPR.
      • Xiphoid Process: Small, fragile bottom section.
    • Rib Cage: 12 sets of ribs.
      • Floating Ribs: 11th and 12th ribs, do not attach to the sternum.
      • Purpose: Protects heart, lungs, and major blood vessels.
      • Breastbone in the center of the chest where ribs connect.

    Pelvis

    • Bones:
      • Ilium: Wing area of the hip.
      • Ischium: Bottom of the pelvis ("butt bone").

      • Humerus: Upper arm bone.
    • Lower Arm:
      • Radius: Thumb side of the lower arm.

        • Middle Phalanges: Middle section of the finger.
        • Proximal Phalange: Base of the finger.
      • Metacarpals: Hand bones.
      • Carpals: Wrist bones.

    • Joints: Points where bones meet.
    • Types:
      • Ball and Socket: Hip.

      • Saddle Joint: Thumb.
      • Condyloid Joint: Wrist.
      • Plane Joint: Ankle.
    • Locations where bones come together, allowing for movement and flexibility.

    Muscles

    • Muscle Types:
      • Voluntary (Skeletal): Conscious control.
      • Involuntary (Smooth): Controlled by the brain stem (e.g., blood vessels, GI tract).
      • Cardiac (Heart): Specific muscle type for the heart.
