Use correct anatomical terminology to describe body directions, body regions, and body planes or sections. Locate and name the major body cavities and their subdivisions and associated membranes, and list the major organs contained within them. Name the four quadrants or nine regions of the abdominopelvic cavity and list the organs they contain. Directional Terms Directional Terms Directional Terms Body Planes and Sections A sagittal section divides the body (or organ) into left and right parts A median, or midsagittal, section divides the body (or organ) into equal left and right parts A frontal section divides the body (or organ) into anterior and posterior parts A transverse, or cross, section divides the body (or organ) into superior and inferior parts Body Cavities Dorsal body cavity Cranial cavity houses the brain Spinal cavity houses the spinal cord Ventral body cavity Thoracic cavity houses heart, lungs and others Abdominopelvic cavity houses digestive system and most urinary system organs Body Cavities Thoracic cavity subdivisions: Two pleural cavities Each houses a lung Mediastinum Contains pericardial cavity Surrounds thoracic organs Pericardial cavity Encloses heart Serous Membranes Thin, double-layered membrane separated by serous fluid Parietal serosa lines internal body walls Visceral serosa covers the internal organs Abdominopelvic Major Organs Abdominopelvic Regions PROPERTIES On passing, 'Finish' button: On failing, 'Finish' button: Allow user to leave quiz: User may view slides after quiz: User may attempt quiz: Goes to Next Slide Goes to Next Slide At any time At any time Unlimited times Activities Regional Terms (Anterior) – Labeling Regional Terms (Posterior) – Labeling Body Cavities – Labeling Body Cavities – Memory Game
