Body Structure Terms
Question | Answer |
---|---|
ascites | Abnormal accumulation of fluid in the abdominal cavity. |
edema | Abnormal accumulation of fluid within tissue spaces. |
adhesion | Abnormal fibrous band that holds or binds together tissues that are normally separated. |
mycosis | Any fungal infection in or on the body. |
excision | Biopsy in which the entire lesion is removed. |
incisional | Biopsy in which only a small sample of the lesion is removed. |
inflammation | Body defense against injury, infection, or allergy marked by redness, swelling, heat, pain, and sometimes, loss of function. |
organelle | Cellular structure that provides a specialized function, such as the nucleus (reproduction), robosomes (protein synthesis), Golgi apparatus (removal of material from the cell), and lysosomes (digestion). |
PET (positron emission testing) | Computed tomography records the positrons (positive charged particles) emitted from a radiopharmaceutical to produce a cross-sectional image of metabolic activity of body tissues to determine the presence of disease. |
gangrene | Death and decay of soft tissue, usually caused by ciculatory obstruction, trauma, or infection. |
infusion therapy | Delivery of fluids directly into the blood stream via a vein for treating various disorders; also called IV therapy. |
cauterize | Destruction of tissue by electricity, freezing, heat, or corrosive chemicals. |
inspection | General observation of the patient as a hole progressing to specific body areas. |
palpation | Gentle application of the hands to a specific structure or body area to determine size, consistency, texture, symmetry, and tenderness of underlying structures. |
US (ultrasound) | High-frequency sound waves (ultrasound) are directed at soft tissue and reflected as "echoes" to produce an image on a monitor of an internal body structure; also called ultrasound, sonography, and echo. |
perforation | Hole that completely penetrates a structure. |
CT (computed tomography) | Imaging technique in which an x-ray emitter rotates around the area to be scanned and a computer measures the intensity of transmitted x-rays from different angles; formerly called computerized axial tomography. |
I & D (incision and drainage) | Incision made to allow the free flow or withdrawal of fluids from a wound or cavity. |
peritonitis | Inflammation of the peritoneum, the serous membrane that surrounds the abdominal cavity and covers its organs. |
blood chemistry | Laboratory test, usually performed on serum, to evaluate various substances to determine whether they fall within a normal range. |
auscultation | Listening to the heart, bowel and lungs with or without a stethoscope to assess the presence and quality of sounds. |
DNA (deoxyribonucleic acid) | Molecule that holds genetic information capable of replicating and producing an exact copy whenever the cell divides. |
diaphragm | Muscular wall that divides the thoracic cavity from the abdominopelvic cavity. |
CBC (complete blood count) | Panel of blood tests used as a broad screening test for anemias, infections, and other diseases. |
febrile | Pertaining to a fever; also called pyretic. |
suppuration | Producing or associated with the generation of pus. |
hernia | Protrusion of any organ through the structure that normally contains it. |
SPECT (single-photon emission computed tomography) | Radiological technique that integrates computed tomography and a radioactive material (tracer). |
ablation | Removal of a part, pathway, or function by surgery, chemical destruction, electrocautery, freezing, or radio frequency. |
biopsy | Removal of a representative tissue sample from a body site for microscopic examination, usually to establish a diagnosis. |
resection | Removal of part or all of a structure, organ, or tissue. |
curettage | Scraping of a body cavity with a spoon-shaped instrument called a curette. |
assessment techniques | Sequence of procedures designed to evaluate the health status of a patient. |
organ-disease panels | Series of blood tests used to evaluate a specific organ (liver panel) or disease (anemia panel). |
chromatin | Structural component of the nucleus, composed of nucleic acids and proteins. |
rupture | Sudden breaking or bursting of a structure or organ. |
metabolism | Sum of all physical and chemical changes that take place in a cell or an organism. |
anastomosis | Surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another. |
revision | Surgical procedure used to replace or compensate for a previously implanted device or correct an undesirable result or effect of a previous surgery. |
percussion | Tapping a structure with the hand or fingers to assess consistency and the presence or absence of fluids within the underlying structure. |
nuclear scan | Technique in which a radioactive material (radiopharmaceutical) called a tracer is introduced into the body (inhaled, ingested, or injected) and a specialized camera (gamma camera) is used to produce images of organs and structures. |
fluoroscopy | Technique in which x-rays are directed through the body to a fluorescent screen that displays internal structures in continuous motion. |
radiography | Technique in which x-rays are passed through the body or area and captured on a film to generate an image; also called an x-ray. |
MRI (magnetic resonance imaging) | Technique that uses radio waves and a strong magnetic field, rather than an x-ray beam, to produce highly detailed, multiplanar, cross-sectional views of soft tissues. |
chromosome | Threadlike structures within the nucleus composed of deoxyribonucleic acid (DNA) that carries hereditary information encoded in genes. |
laser surgery | Use of a high intensity laser light beam to remove diseased tissues, stop bleeding blood vessels, or for cosmetic purposes. |
endoscopy | Visual examination of a body cavity or canal using a specialized lighted instrument called an endoscope. |
sepsis | Pathological state, usually febrile, resulting from the presence of microorganisims or their products in the bloodstream. |
