front of the body/back of the body

vertical line dividing body into right and left sides

vertical line dividing body into front and back sides

horizontal line dividing body into superior and inferior portions

formed by cranial bones, contains brain. protective tissue lining this is the meninges

chest cavity, contains pleural and pericardial cavities and mediastinum

contains stomach, spleen, lilver, gallbladder, small intestine and most of the large intestine, the serous membrane of this cavity is the peritoneum

contains urinary bladder, portions of large intestine and internal organs

fluid filled space surround each of the lungs, the serous membrane of this is the pleura

fluid filled space that surrounds the heart, the serous membrane is the pericardium

serous membrane of the abdominal cavity

anatomic region in central portion of the thoracic cavity b/w medial walls of pleural cavities, contains the structures in thoracic cavity except for lungs (ie: heart, thymus, esophagus, trachea and blood vessels)

dome shaped muscle separating the thoracic cavity from the abdominopelvic cavity

lines the walls of the cavities

covers the viscera within the cavities

mouth and teeth

nose

eyes

small bones of the middle ear

joints

produce image of interior structure, do not pass easily through bone, useful for soft tissue at low dose (ie: breast-mammogram, bone densitometry)

High energy magnetic field - protons in body align with field, color image appears on video monitor. Used for differentiating NORMAL from ABNORMAL tissues (ie: tumors, brain abnormalities, blood flow)

3-D structures to visualize soft tissue in more detail than x-ray, tissue intensities showing different degrees of gray. Whole body CT-scans are performed (ie: lung and kidney cancers, coronary artery disease)

High freq. sound waves, painless, noninvasive, no dies. Performed during pregnancy to view fetus

Video of inside of the body. endoscope is the instrument used with lens (ie: colonoscopy = interior of colon, laparoscopy = organs of abdominopelvic cavity, arthroscopy = interior of the joint)
