| tissues | Groups of cells that perform a specialized activity |
| histology | The study of tissues |
| four major tissues | epithelial, connective, muscle, & nervous |
| epithelial tissue | forms the epidermis of skin, covers surfaces oforgans, lines cavities, forms tubes etc |
| connective tissue | supports and connects other tissues and organs |
| muscle tissue | all contractile tissue of body |
| nervous tissue | all tissue capable of transmitting electrical impulses |
| organs | body sturctures composed of at least two different tissue types |
| systems | composed of at least one organ and accessory structure |
| organism | highest level of organization. complete living entity |
| levels of organization | cells, tissues, organs, systems, organism |
| disease | pathological or morbid condition |
| signs | objective indicators that are observable by others |
| symptoms | subjective and is experienced by patient |
| clincal findings | results of laboratory examiniations |
| homeostasis | stable internal environment required by body cells for survival |
| pathology | when homeostasis is interrupted |
| pathogenesis | study of progression of a disease |
| etiology | study of all factors involved in development of a disease |
| metabolic | diabetes |
| infectious | measles, mumps |
| congenital | harelip |
| hereditary | hemophilia |
| environmental | burns, trama |
| neoplastic | cancer |
| diagnosis | establishing the cause and nature of a disease |
| prognosis | prediction of course of disease and its probable outcome. |
| idiopathic | any disease whose cause is unknown |
| anatomical position | placement of body accepted by anatomists throughout world. |
| planes of the body | midsagittal, sagittal, coronal, transverse |
| midsagittal | right and left halves |
| sagittal | unequal right and left sides |
| coronal or frontal | front side(anterior or ventral aspect) and back side ( posterior or dorsal aspect) |
| transverse or horizontal | upper portion (superior aspect) and lower portion ( inferior aspect) |
| dorsal cavities | cranial and spinal |
| ventrial cavities | thoracic, pelvic |
| visceral | internal |
| abdominopelvic region | consist of nine regions |
| rt hypochondriac | ur region beneath the ribs |
| epigastric | region of the stomach |
| left hypochondriac | ul region beneath the ribs |
| rt lumbar | rt middle lat region |
| umbilical | region of the navel |
| left lumbar | left middle lateral region |
| rt inguinal | rl lat region |
| hypogastric | lower midle region beneath the navel |
| left inguinal | left lower lat region |
| four quadrants | RUQ, LUQ, RLQ, LLQ |
| radiography | roentgenographny |
| x-ray examination | oldest method of examining underlying structures |
| radiopaque materials | substances that absorb x-rays |
| CT scan | computed tomography scan |
| MRI | magnetic resonance imaging |
| RF waves | radiofrequency waves |
| ultrasonography | reflects high-frequency sound waves off internal tissues |
| spine | spina |
| division of spine | cervical, thoracic, lumbar, sacral, coccyx |
| cervical | neck |
| thoracic | chest |
| lumbar | loin |
| sacral | lower back |
| coccyx | tailbone |
| nucle/o | nucleus |
| poster/o | back(of body), behind, posterior |
| proxim/o | near |
| radi/o | radiation, x-ray |
| ventr/o | belly, belly-side |
| viscer/o | internal orgns |
