Human Anatomy
Intro Terms
| Question | Answer |
|---|---|
| Anatomy | the cutting up or dissection of the body; a study of the structure of an organism and the relationship of its parts |
| Surface Anatomy | study of form (morphology) and markings on the surface of the body |
| Gross Anatomy | structure observed with the unaided eye (without a microscope) i.e. cadavers Two approaches: regional and systematic |
| Microscopic Anatomy | devoted to finer detail; microscope is used as an aid |
| Cytology | the study of cells |
| Histology | the study of tissues |
| Optical (Light) Microscopes | phase contrast, ultraviolet, etc. |
| Transmission Electron Microscope | see ultrastructure |
| Scanning Electron Microscope | see ultrustructure |
| Developmental Anatomy | the study of the human body from conception (zygote, i.e. unicellular embryo formation) to adult form |
| Embryology | unicellular sygote to the end of the 8th week in utero |
| Fetology | 9th week to parturition |
| Endoscopy | a narrow, flexible tube with light is inserted into hollow organs via external openings |
| Endoscope | mouth to throat to esophagus to stomach (to see ulcers) |
| Proctoscope or Sigmoidoscope | anal opening to anal canal to rectum to colon (to see hemorrhoids meaning flowing blood, or polyps with colonoscopy) |
| Pathological Anatomy | the study of structureal changes associated with disease |
| Radiographic Anatomy | x-rays are passed through organs and shadows are cast on photographic film |
| Single Barrage (x-ray) or Roentgenogram | a flat image |
| Computer Assisted Tomography | 3-D image of a cross sectional picture |
| Digital Subtraction Angiography | an x-ray image before and after intraveneous iodine allows isolation of arteries |
| Dynamic Spatial Reconstructor | constructs a moving, 3-D lifesize image of an internal organ |
| Ultrasound or Sonography | a device emits a high-frequency sound (radar) and records the echo on a monitor |
| Scintigraphy (Nuclear Medicine) | unstable radioisotopes are introduced into the body, different organs collect and concentrate them; a scintillation counter scans the body and produces and image |
| Positron Emission Tomography | radioisotopes are mroe precisely localized with the aid of computer imaging techniques |
| Magnetic Resonance Imaging or Nuclear Magnetic Resonance | determines if the nuclei of a single element behave normally in response to magnetism; Noninvasive and does not use radiation |
| Systems | integumentary, skeletal, muscular, cardiovascular, lymphatic, nervous, endocrine, respiratory, digestive, urinary, reproductive |
