    This lab is designed to take place over two 3-hour lab periods, with one lab period devoted to comparison of invertebrate and vertebrate systems and one devoted to comparison across vertebrate systems. The lab manual and instructor guidelines are formatted in this way to support two lab periods.

    Comparative Anatomy Lab I

    Edit section

    Objectives: Introduce students to the animal anatomy and physiology, with a focus on form and function. Compare invertebrate and vertebrate systems.

    At Evergreen Valley College we use squid and frogs as representative dissections for invertebrates and vertebrates.

    How do animal bodies solve problems? All animals need to obtain oxygen, transport things within the body, obtain and digest food, move, protect their bodies, reproduce, and more. Shaped by evolutionary pressures, animals will have different anatomy to support the physiology (function) of their systems in their environment.

    Pull sheets contain materials for a 25 student lab, with three of each animal dissected during the lab period. Students begin by drawing and labeling external anatomy of both the squid and the frog. Groups of 4-5 students are paired up with another group, such that one group of students dissects the squid, the other dissects the frog, and all students examine, draw, and label the internal anatomy of both the squid and the frog. Use of six total animals per class allows for contact and opportunity for all students, while being aware of budget limitations and maximal educational value of the use of animals.

    Pull sheets include personal protective equipment (PPE) for students and appropriate disposal mechanisms for biohazardous material. Ensure dissections completed at your institution are using appropriate safety procedures and disposal adheres to local and federal guidelines.

    Comparative Anatomy Lab II

    Edit section

    Objectives: Compare body systems of animals across vertebrate taxa. Students dissect birds and mammals, and compare these dissections to their previous work on amphibians. Dissection comparison is enhanced by a comparison of vertebrate skeletal systems, with full skeletons and skull models on display.

    Pull sheets contain specimens, models, slides, and posters in use at Evergreen Valley College. Lab may be modified depending on resources and availability of specimens at adopting institution.
