The correct spelling of the word "laboratory animal" is /ləˈbɒrət(ə)ri/ /ˈænɪməl/. The first part, "laboratory," is spelled with an "o" after the "r" and pronounced as "a" because of the unstressed syllable, as denoted by the schwa symbol /ə/. The second part, "animal," is pronounced with stress on the first syllable, symbolized by /ˈ/, and with the letter "i" pronounced as "e" because of the following "m." This term refers to animals used for experimental research in an laboratory setting.
A laboratory animal refers to any living creature that is specifically used for scientific research and experimentation in a controlled laboratory setting. These animals can include a wide range of species, such as mice, rats, rabbits, guinea pigs, hamsters, dogs, cats, monkeys, and even certain reptiles and fishes. Their primary purpose is to serve as models for mimicking various biological processes, diseases, or conditions that closely resemble those found in humans.
Laboratory animals are meticulously selected and bred to possess particular genetic characteristics or traits that make them suitable for specific research objectives. They are typically housed and maintained under strict laboratory conditions, ensuring their proper care, nutrition, and hygiene. These animals are used to study various aspects of biology, genetics, physiology, medicine, psychology, toxicology, and pharmacology.
The utilization of laboratory animals allows scientists and researchers to perform controlled experiments, closely monitor and analyze their responses to different treatments or interventions, and more accurately predict potential outcomes in human subjects. However, it is essential to adhere to stringent ethical guidelines and regulations to protect the welfare and minimize any potential harm to these animals. The development of alternative methods, such as in vitro tests, computer simulations, and tissue cultures, continues to reduce the reliance on laboratory animals in scientific research, aiming to promote their humane and responsible use.
The term "laboratory animal" combines two words: "laboratory" and "animal".
The word "laboratory" originates from the Latin word "laboratorium", which referred to a workplace or a place of labor. It was derived from the Latin word "laborare", meaning "to labor or work". Over time, the term "laboratory" evolved to specifically denote a place equipped for scientific research and experimentation.
The word "animal" comes from the Latin word "anima", meaning "breath" or "soul". In Latin, "animal" was used to describe any living creature capable of movement and sensation.
When combined, "laboratory animal" refers to an animal used in scientific research or experimentation within a laboratory setting.
