Gel-like substance that surrounds the nucleus of a cell but is contained within the cell membrane. cytoplasm Molecule that holds genetic informaton and makes an exact copy of itself whenever the cell divides. deoxyribonucleic acid (DNA) Indentificaton of a disease or condition by scientific evaluation of physical signs, symptoms, history, laboratory and clinical test results, and radiographic procedures. diagnosis Instrument consisting of a rigid or flexible fiberoptic tube and optical system for observing the inside of a hollow organ or cavity. endoscope Study of the causes of disease. etiology Instrument, consisting of an x-ray machine and a fluorescent screen, used to view the internal organs of the body. fluoroscope Pertaining to conditions without clear pathogenesis, or disease without recognizable cause, as of spontaneous origin. idiopathic Chemical changes that take place in a cell or an organism and produce energy and basic materials needed for all life processes. metabolism Predicion of the course and end of a disease and the estimated chance of recovery. prognosis Any objective evidence or manifestation of an illness or a disordered function of the body. sign Any change in the body or its functions as perceived by the patient. symptom Movement away from the median plane of the body or one of its parts. abduction Movement toward the median plane of the body. adduction Pertaining to the midline of the body or structure. medial Pertaining to a side. lateral Toward the head or upper portion of a structure. superior (cephalad) Away from the head, or toward the tail or lower part of a structure. inferior (caudal) Nearer to the center (trunk of the body) or to the point of attachment to the body. proximal Further from the center (trunk of the body) or from the point of attachment to the body. distal Near the front of the body. anterior (ventral) Near the back of the body. posterior (dorsal) Pertaining to the outer wall of the body cavity. parietal Pertaining to the viscera, or internal organs, especially the abdominal organs. visceral Lying horizontal with the face downward, or indicating the hand with palms turned downward. prone Lying on the back with the face upward, or indication the position of the hand or foot with the palm or foot facing upward. supine Turning inward or inside out. inversion Turning outward. eversion Pertaining to the palm of the hand. palmar Pertaining to the sole of the foot. plantar Toward the surface of the body. superficial Away from the surface of the body (internal) deep Abnormal fibrous band that holds normally seperated tissues together, usually occuring within a body cavity. adhesion Substance being analyzed or tested, generally by means of a chemical. analyte In radiology, a substance that is injected into the body, introduced via catheter, or swallowed to facilitate radiographic imaging of internal structures that otherwise are difficult to visualize on x-ray films. contrast medium Bursting open of a wound, especially a surgical abdominal wound. dehiscence Feverish; pertaining to a fever. febrile Body defense against injury, infection, or allergy marked by redness, swelling, heat, pain and, sometimes, loss of function. inflammation Diseased; pertaining to a disease. morbid Branch of medicine concerned with the use of radioactive substances for diagnosis, treatment, and research. nuclear medicine Medical discipline concerned with the use of electromagnetic radiation, ultrasound, and imaging techniques for diagnosis and treatment of disease and injury. radiology Medical imaging using external sources of radiation to evaluate body structures and functions of organs. diagnostic Use of imaging techniques in the nonsurgical treatment of various disorders, such as balloon angioplasty and cardiac catheterization. interventional Use of ionizing radiation in the treatment of malignant tumors. therapeutic Substances that emit radiation spontaneously radionuclides Radionuclide attached to a protein, sugar, or other substance that travels to the organ or area of the body that will be scanned. radiopharmaceutical Term used to describe a computerized image by modality or by structure. scan Pathological state, usually febrile, resulting from the presence of microorganisms or their products in the bloodstream. sepsis Producing or associated with generation of pus suppurative
