Most biology classes will have some form of dissection – the frog is the most common.  However, if you do not do an actual dissection, many of the sections below contain links to virtual dissections and image files.


Frog Dissection

Frog External Anatomy  – legs, eyes, mouth structures
Frog Dissection   –  major organs of the digestive, urogenital, and circulatory and respiratory systems
Frog Brain and Bones – remove the frog’s brain, expose the bones of the lower leg

Frog Dissection Crossword – review terms and procedures
Observe a Living Frog – non dissection, behavior and characteristics
Bullfrog Dissection – bullfrog dissection guides, more advanced than basic frog dissection

Frog Dissection Alternative – for students who do not wish to dissect a frog, project using internet resources
Frog Anatomy Review – resource site for virtual frogs and practice quizzes
Frog Anatomy Labeling – basic pictures of frogs for students to label, serves as a review for the lab test

Frog Dissection Gallery – collection of labeled and unlabeled images of the frog

Fetal Pig

Fetal Pig Dissection  – procedure for the dissection
Fetal Pig Dissection Review  – resources for studying
Fetal Pig Lab Guide – lists structures and check boxes

Fetal Pig Gallery – collection of labeled and unlabeled images

Other Organisms

Planarian Observation – test response to light and food, observe regeneration

Observation of a Live Earthworm – examine an annelid, observe its behavior
Earthworm Anatomy – dissect an earthworm, locate major structures
Earthworm Virtual Dissection – using animation and photos, alternative to real dissection
Earthworm Labeling – image of an earthworm, label its parts

Squid Dissection – describes procedure for dissecting a squid and identifying structures
Virtual Squid Dissection – walk-through guide with photos of the squid

Crayfish External Anatomy  – focusing on the appendages and mouthparts
Crayfish Dissection – the body cavity is exposed to reveal structures such as gills and the green gland
Crayfish Virtual Dissection – images and walk-through of crayfish dissection

Grasshopper Anatomy – examines the appendages and mouth parts
Fish Anatomy – coloring guide, fish organs and analyze fish age by scale rings
Fish Observation – view a live goldfish, take data on breathing rates

Rat Dissection

Introduction – rat classification, body regions, terminology
External – general external structures, skinning of the rat to expose muscles and bone
Head, Thoracic, Abdominal – digestive system, heart, lungs
Urogenital System – kidneys, reproductive organs
Circulatory – major veins and arteries
