ANTR 350 Lecture 2Outline of Last Lecture I. Introductory topics in anatomyII. Level of human structural organizationIII. Anatomical terminologyIV. Standard anatomical planesOutline of Current Lecture I. Abdominopelvic regions and quadrantsII. Body cavitiesIII. Trunk body wall layersCurrent Lecture- abdominopelvic regions and quadrantso 4 regions formed by intersecting median (midsagittal) and transumbilical plane-forms right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadranto 9 abdominopelvic regions formed by intersecting… subcostal plane supracristal plane right midclavicular plane left midclavicular planeo don't need to know the names of the regions formed, just know planes used to make them- body cavities1. ventral body cavity (aka coelom) larger than the dorsal cavity contains the viscera all subdivisions are lined by serous membranes (prevent friction between organ and the sac that it is contained in) thoracic cavity: found in the chest mediastinum: connective tissue partition between the right and left pleural cavities, which contains the esophagus, trachea, major blood vessels and nerves, heart and pericardiumThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. right pleural cavity: surrounds right lung left pleural cavity: surrounds left lung abdominopelvic cavity: contains the peritoneal sac and 2 cavities2. dorsal body cavity protects the central nervous system cranial cavity: contains brain, meninges, and CSF spinal cavity: contains spinal cord, meninges. And CSF no serous membranes like in ventral body cavity- trunk body wall layers (from superficial to deep)1. skin (aka cutaneous membrane, epidermis + dermis)2. superficial fascia (aka hypodermis or subcutaneous tissue) fatty layer under skin insulation subcutaneous injections3. deep investing fascia of skeletal muscle tissues keeps muscles separate like wrapping chicken in cling wrap before you freeze it so that they don't stick together4. internal fascia acts like glue for parietal serous membrane very thin5. parietal layer of serous membrane on the wall of organ prevents
