A & P Lecture Chapter 1
Show Answers:

  1. Feeling a structure with hands, such as palpating a swollen lymph node or taking a pulse.
  2. Study of Structure
  3. Study of function physiology
    Study of functions
  4. Is listening to natural sounds made by the body, such as heart and lung sounds.
    Auscultation (AWS-cul-TAY-shun)
  5. The examiner taps on the body, feels for abnormal resistance, and listens to the emitted sound for signs of abnormalities such as pockets of fluid or air
  6. Ultimately, the functions of the body results from its individual cells. To see those, we usually take tissue specimens, thinly slice stain them. and observe them under microscope. This approach is called
  7. The"Father of medicine" however is usually considered to be the Greek physicans
  8. 1839 Botanist and Zoologist, concluded that all organs were composed of cells. Although it took another century for the idea to be generally accepted. Its became the first tenet 
    of the cell theory.
    Schleiden & Schwann
  9. Perhaps the most important break through in bio medical history; all functions of the body are now interpreted.
    Cell Theory
  10. The number of subjects(animals or people) used in a study is the
    Sample size
  11. In this procedure, neither the subject to whom a treatment is given nor the person giving it and recording the results knows whether that subject is receiving the experiment treatment or placebo
    Double blind method
  12. The principle of theory of how evolution works. This brings about the genetic change in the population that contributes evolution
    Natural Selection
  13. Standing and walking on two legs-easier
  14. Is a group of organs with unique collective functions, such as circulation, respiration, or digestion
    Organ system
  15. Structure composed of two or more tissue types that work together to carry out a particular function
  16. Is a mass of similar cells and cell products that forms a discrete region of an organ and performs a specific function
  17. Are smallest unit of organisms that carry out all the basic functions of life; Nothing smaller then a this is considered alive
  18. Are microscopic structure n a cell that carry out its individual functions.  Ex: Mitochondria, Centrioles, and lysosomes
  19. Although the environment around an organism changes, the organism maintains relatively stable internal conditions. This ability to maintain internal stability is called
  20. The fundamental mechanism that keeps a variable close to its set point is? A process in which the body senses a change and activities mechanisms that negate or reverse it. By maintaining stability in this, it is the mechanism for maintaining health
    Negative Feedback
  21. Because feedback mechanism alter the original changes that triggered them (temperature, for example), they are often called 
    Feedback Loops
  22. Is a structure that senses a change in the body. Such as the stretch ________ that monitor blood pressure
  23. Such as the cardiac center of the brain, is a mechanism that processes this information, relates it to other available information( for example, comparing what the blood pressure is with what should be), and "makes a decision" about what the appropriate response should be
    Integrating (control) center
  24. Is the cell or organ that carries out the final corrective action
  25. Is a self-amplifying cycle in which a physiological change leads to greater change in the same direction, rather than producing the corrective effects of 
    Positive feedback
  26. Is an explanatory statement or set of statements derived from facts, laws, and confirmed hypothesis
  27. Is information that can be independently verified by any trained person
  28. Can be applied to data
    Statistical tests
  29. A substance with no physiological effect on the body
  30. Consist of subjects that are as much like treatment group as possible except with respect to the variable being tested
    Control Group
  31. Living things exhibit a far higher level of organization than the nonliving world around them.
  32. Living matter is always compartmentalized into one or more cells
    Cellular Composition
  33. Living things take in molecules from the environment and chemically change them into molecules that form their own structures, control their physiology, or provide them with energy.Is the sum of all this internal change
