Chapter 2 - Body Structure Flashcards
transverse plane
horizontal plane or cross-sectional plane
Adhesion
band of scar tissue binding anatomical surfaces that normally are separate from each other.
Inflammation
protective response of body tissues to irritation, infection or allergy
Sepsis
body’s inflammatory response to infection, in which there is fever, elevated heart and respiratory rate, and low blood pressure
Computed Tomography (CT) Scan
radiographic technique that uses a narrow beam of x-rays, which rotates in a full arc around the patient to image the body in a cross-sectional slices.
Endoscopy
visual examination of the interior of organs and cavities with a specialized lighted instrument called an endoscope.
Fluoroscopy
radiographic procedure that directs x-rays through the body to a fluorescent screen to view the motion of organs
Magnetic Resonance Imaging
radiographic technique that uses electromagenetic energy to produce multiplanar cross-sectional images of the body
Nuclear Scan
diagnostic technique that produces an image by recording the conc. of a radiopharmaceutical which is introduced by ingestion, inhalation, or injection, and is specifically drawn to the area under study
Position Emission Tomography
radiographic technique that combines CT with the use of radiopharmaceuticals. PET produces a cross-sectional image of the disbursement of radioactivity in a section of the body to reveal the areas where the radiopharmaceutical is being metabolized
Radiography
Production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from an external source.
Radiopharmaceutical
a drug that contains a radioactive substance that travels to an area or a specific organ that will be scanned
Scan
technique for carefully studying an area, organ, or system of the body by recording and displaying an image of the area.
Single-photon emission computed tomography
type of nuclear imaging study to scan organs after injection of a radioactive tracer. It is similar to PET scans, but employs a specialized gamma camera that detects emitted radiation to produce a 3D image from a composite of numerous views.
Tomography
radiographic technique that produces a film representing a detailed cross-section of tissue structure at a predetermined depth
Ultrasonography
imaging technique that uses high-frequency sound waves that bounce off of body tissues and are recorded to produce an image of an internal organ or structure
Anastomosis
connection between two vessels; surgical joining of two ducts, blood vessels, or bowel segments to allow flow from one to the other
Cauterize
Process of burning tissue by thermal heat, including steam, electricity, or another agent, such as a laser or dry ice.
Chondroma
tumor composed of cartilage
Cytometer
instrument for counting and measuring cells within a specified amount of fluid such as blood, urine, or cerebrospinal fluid
Histolysis
separation, destruction, or loosening of tissue
Nuclear
pertaining to a cellular, atomic, or anatomical nucleus
Anterior
toward the front of the body, organ or structure
Caudad
toward the tail; in a posterior direction
