MODULE 1: INTRODUCTION TO LAB.AN. Flashcards
Refers to the scientific study of animals, usually in the laboratory, for the purpose of gaining new biological knowledge or solving medical problems
Animal experimentation
Application of veterinary medicine and animal science to the acquisition of laboratory animals and to their management
Laboratory animal care
Specialty field within veterinary medicine that is concerned with the diagnosis, treatment, and disease prevention in animals
Laboratory animal medicine
Study of nature, cause and cure of abnormal structure and function in people, animals and plants
Comparative medicine
Body of scientific and technical information that bears on both laboratory animal care and medicine
Laboratory animal science
Group of animals constantly used in laboratories for general research
Laboratory animals
- Founder of biology
- First to conduct disections that revealed internal differences among animals
Aristotle
- First to perform experiments on living animals
- Established in pigs that the trachea was an air tube and the lungs were pneumatic organs
Erasistratus
Perform anatomical dissection of pigs and monkeys
Galen

Reported the first measurement of bp. using a horse
Stephen Hales
Studied infectious disease in a variety of animals:
Silkworms = pebrine
Sheep = anthrax
Dogs = rabies

Prototherians
Give birth to partly-developed embryos that complete their development in the marsupium pouch
Metatherians
Possess a placenta
Eutherians
Born at a very early stage of development, eyes closed, no hairs, no dentary-squamosal joint.
Altricial offspring
Open eyes in 1 or 2 days and are capable of getting up and walking around shortly after birth
Precocial young
