#1
Which of the following laboratory animals is commonly used in immunology research?
Mouse
ExplanationMice are commonly used in immunology research due to their genetic and immunological similarities to humans.
#2
What does the term 'biosecurity' refer to in laboratory animal facilities?
Protecting animals from disease and preventing the spread of pathogens
ExplanationBiosecurity measures aim to safeguard animals from diseases and prevent the transmission of pathogens within the facility.
#3
Which organization provides guidelines and standards for the care and use of laboratory animals?
NIH (National Institutes of Health)
ExplanationThe NIH sets guidelines and standards to ensure the ethical and humane treatment of laboratory animals.
#4
Which of the following is a commonly used analgesic (pain reliever) for laboratory animals?
Morphine
ExplanationMorphine is a commonly used analgesic for relieving pain in laboratory animals, although its use requires careful consideration of potential side effects.
#5
What is the purpose of using anesthetics during surgical procedures on laboratory animals?
To induce unconsciousness and prevent pain
ExplanationAnesthetics are used during surgical procedures on laboratory animals to induce unconsciousness and prevent pain, ensuring the welfare of the animals.
#6
Which term describes the process of removing an animal from the study due to illness or other factors?
Exclusion
ExplanationExclusion refers to the removal of an animal from a study due to illness, non-compliance, or other factors that could compromise the research.
#7
What does the term 'inbred strain' refer to in laboratory animal science?
A group of animals from the same species and strain, bred to be genetically identical
ExplanationInbred strains are genetically uniform groups of animals, ensuring consistency in research results.
#8
What is the purpose of a sentinel animal in laboratory animal facilities?
To detect the presence of pathogens by being deliberately exposed to them
ExplanationSentinel animals help monitor the health status of other animals in the facility by being intentionally exposed to pathogens.
#9
Which term refers to the process of introducing an animal to a new environment to adapt to it before experimentation?
Acclimatization
ExplanationAcclimatization is the process of helping animals adjust to a new environment or conditions before experimentation to minimize stress.
#10
Which laboratory animal is commonly used in cardiovascular research due to its similar heart anatomy to humans?
Dog
ExplanationDogs are often used in cardiovascular research because of their cardiac similarities to humans.
#11
What is the term for the process of breeding animals with specific genetic traits for research purposes?
Selective breeding
ExplanationSelective breeding involves breeding animals to express desired traits over successive generations.
#12
Which of the following is NOT a commonly used method for identifying laboratory animals?
Facial recognition
ExplanationFacial recognition is not commonly used for identifying laboratory animals compared to other methods like ear tags or microchips.
#13
What is the approximate body temperature range (in Celsius) of laboratory mice?
35-37°C
ExplanationLaboratory mice typically maintain body temperatures between 35-37°C, similar to humans.
#14
What is the term for the process of breeding animals to express a particular trait over several generations?
Selectively breeding
ExplanationSelectively breeding involves breeding animals to express specific traits through controlled mating over multiple generations.
