The laboratory rat (Rattus norvegicus) is a widely used model organism in scientific research, particularly in the fields of biology, medicine, and psychology. Rats are mammals that share many similarities with humans in terms of their anatomy, physiology, and genetic makeup, making them an ideal species for studying human biology and disease. The rat dissection lab offers a unique opportunity for students to explore the anatomy of a mammal, gaining insights into the organization and function of various organ systems, and developing a deeper appreciation for the complexity and beauty of biological systems.
Begin by establishing the importance of mammalian biology. Mammals represent a highly successful group of vertebrates characterized by homeothermy (warm-bloodedness), hair, and specialized reproductive mechanisms. The brown rat ( Rattus norvegicus ) is an excellent representative of the class Mammalia, exhibiting a highly developed nervous system, a complex, closed double-circuit circulatory system, and distinct compartmentalized body cavities. 2.

For a rat dissection specifically, the introduction is your opportunity to explain why the rat ( Rattus norvegicus ) is an ideal model organism for studying mammalian anatomy and how the dissection connects to broader concepts in comparative anatomy, medicine, and evolutionary biology.

The rat's diet demands hindgut fermentation to break down cellulose. Continuous foraging eliminates the need for bile storage.
Feature a duplex uterus consisting of two distinct uterine horns ( cornua ). This structural divergence from the simplex human uterus accommodates large litters (superfetation and multiparity). 4. Rationale for Using the Rat as a Comparative Model
