Kerry Rowe September 9, 2010 Section 001 BIOL 3350 Fall 2009 Test 1 Review 1.   Define Anatomy-  science dealing with the structure of human body          2.   Define Physiology-  physical and chemical mechanisms by which anatomy works.  Functions of  the human body .          3.   Define Metabolism and its two categories-  chemical reactions that turn one molecule into another.  Catabolism-  reproducing simple from complex; Anabolism-  produce complex from simple 4.   List the levels of structural organization in increasing order-  chemical-cell-tissue-organ-organ  system-organism           5.   Define Homeostasis-  the same state or condition 6.   Define the two feedback mechanisms and give examples of each mechanism-  negative feedback   mechanism-  when the function or value increases or decreases beyond a certain level, this  mechanism brings that function or value back to the set point. Ex: when there is too much or not  enough glucose in the blood, the liver receives a signal to increase or decrease the level of glucose  being secreted into the blood.  Positive feedback mechanisms-  produces a cycle initiating stimulus to  produce more of the same value or function. Ex: an increase in environmental temperature would  cause an increase in body temperature. 7.   List the three major components of a negative feedback mechanism-  sensor (nerves), integrator  (brain or spinal cord) and effector  (muscle-pulls away)   8.    Principle of Complementarity of structure and function- connection and interdependence of body structures; how the structure and function work together 9.   Examples of ectoparasites-  fleas, ticks, lice 10.   Vectors of infectious disease the transmitters of disease-causing organisms that carry the pathogens from one host to another.   11.   Define Incidence-  the rate at which a certain event occurs

12.   Define Normal Micro flora-  harmless bacteria that are normally found on the internal and  external exposed areas of the human body 13.   Define Opportunistic Pathogens-  a usually harmless microorganism that may produce an  infectious disease when the host is in a weakened state from illness, famine, or medical therapy 14.   Define Prokaryotes-  organism with cells lacking a true nucleus and nuclear membrane that  reproduces through simple fusion. 15.   Gram Staining is used on  bacteria to separate and indentify different types of bacteria. 16.   Fungi that reproduce by budding-
