  1. Health Science 1101Medical Terminology Module 2 Body Structure

  2. Body Structure Smallest to largest structures Location of structures Position of structures in reference to each other How we visualize structures

  3. Levels of Organization • Nucleus nucle/o • Cellcyt/o • Tissue hist/o • Chemical • Atomic • Molecular • Cellular • Tissue • Organ • System • Organism

  4. Location of Structures Body Cavities Dorsal -Cranial -Vertebral Ventral -Thoracic -Abdominopelvic

  5. Body Cavity/Structure Terms spin/o thorac/o abdomin/o crani/o dorso/o cervic/o chondr/o Medical Terminology Simplified, 4th edition

  6. Quadrants of the Abdominopelvic Cavity Right Upper Quadrant (RUQ) Left Upper Quadrant (LUQ) Right Lower Quadrant (RLQ) Left Lower Quadrant (LLQ)

  7. The 9 Abdominopelvic Regions Gastr/o Ili/o Inguin/o Lumb/o Umbilic/o Pelv/i

  8. Body Planes Sagittal -midsagittal Frontal (coronal) Transverse (horizontal)

  9. Body Position Anatomical Position Serves as a reference point for location and position of body parts

  10. Positions Superior ̶ Inferior Medial ̶ Lateral Proximal ̶ Distal Anterior ̶ Posterior Ventral ̶ Dorsal Cephal/o̶Caud/o

  11. Position Terms Anterior (Anter/o) Posterior (Poster/o) Dorsal (Dors/o) Ventral (Ventr/o) Lateral (Later/o) Medial (Medi/o) Caudal (Caud/o) Cephalic (Cephal/o) Inferior (Infer/o) Superior (Superi/o) Distal (Dist/o) Proximal (Proxim/o)

  12. Body Movements Flexion Extension Pronation Supination Abduction Adduction http://tle.westone.wa.gov.au/content/file/969144ed-0d3b-fa04-2e88-8b23de2a630c/1/human_bio_science_3b.zip/content/003_musculo_skeletal_support/page_11.htm

  13. Visualizing Structures AKA: Imaging Techniques Scan: Technique for carefully studying an area, organ or system by recording and displaying multiple images of the area. Ultrasonography (US): Imaging technique that uses high-frequency sound waves, ultrasound, that bounce off body tissues and are recorded to produce an image of an organ or tissue. Radiography: Production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from an external source.

  14. More Imaging Techniques Fluoroscopy: Radiographic procedure that uses a fluorescent screen instead of a photographic plate. Radiopharmaceutical: Drug that contains a radioactive substance that travels to an area or a specific organ that will be scanned. Nuclear Scan: Diagnostic technique that produces an image by recording the concentration of a radiopharmaceutical called a radionuclide which is detected by a scanning device.

  15. Even More Imaging Techniques Tomography: Any technique that produces a film representing a detailed cross section of tissue structure at a predetermined depth. Computed Tomography (CT): Radiographic technique that uses a narrow beam of x-rays, rotating in a full arc around the patient to image the body in cross sectional slices. Magnetic Resonance Imaging (MRI): Radiographic techniques that use electromagnetic energy to produce cross-sectional images of the body at many planes.

  16. Still More Imaging Techniques Positron Emission Tomography (PET): Radiographic technique which combines computed tomography and the use of radiopharmaceuticals (radioactively labeled drugs). Good for disorders like stroke, epilepsy and Alzheimer's. Single-Photon Emission Computed Tomorgraphy (SPECT): Type of nuclear imaging study to scan organs after an injection of a radioactive tracer. Like PET scan but typically produces 3D images. Endoscopy: visual examination of interior of organs using a specialized lighted instrument called an endoscope.

  17. Other Body Structure Terms Adhesion: Band of scar tissue binding surfaces that are normally separate from each other. Anastomosis: 1. Connection between two blood vessels or 2. Surgical joining of two ducts, vessels or bowel segments. Cauterize: Process of burning tissue by thermal heat, electricity, laser, or dry ice.

  18. More Other Body Structure Terms Inflammation: Protective response of body tissues to infection or allergy. Signs include: Sepsis: Inflammatory response to infection characterized by fever, elevated heart and respiratory rate and low blood pressure.
