1 Prepare the dissection tray and get your frog. Frogs and other small animals are typically dissected in biology labs to learn anatomy. If your class is going to dissect a frog, your teacher should provide all the necessary tools for the job. It doesn't take much, though.

Frog Dissection Diagram and Labeling
Dissection Instructions. Place the frog in the dissecting pan ventral side up. Use scissors to lift the abdominal muscles away from the body cavity. Cut along the midline of the body to the forelimbs. Make transverse (horizontal) cuts near the arms and legs. Life the flaps of the body wall and pin back. Frog Internal Anatomy - Dissection Guide. Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Background: As members of the class Amphibia, frogs may live some of their adult lives on land, but they must return to water to reproduce. Eggs are laid and fertilized in water. On the outside of the frog's head are two external nares, or nostrils; two tympani, or eardrums; and two eyes, each of which has three lids.

Frog Dissection Frogs are excellent model organisms for scientific studies of development, behavior, anatomy, and physiology. They are commonly used in biology classes as representative vertebrates with specialized amphibian characteristics and behaviors. Frog dissection is a common laboratory technique used to study the anatomy of the amphibian. The procedure involves opening up the frog's body and examining its internal organs, skeletal system, and circulatory system. Dissection and Anatomy Resources. HS-LS1-2 Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. Students use this guide to dissect the frog. Worksheet includes external and internal anatomy with instructions. Students answer questions and label.
Frog Dissection
Label the diagram of the external anatomy of a frog's body: (Word bank: head, trunk, forelimb, upper arm, wrist, hand, finger, digits, male pad, hindlimb, thigh, shank, ankle, foot, webbed toes). 1 2 9 6 4 8 5 7 3 11 12 13 10 14 15 2. 5. First, cut the length of the frog, then cut across the frog horizontally just under the arms and at the top of the thighs. Be careful that you cut muscle. Avoid cutting into the organs of the frog. The trick to this is to go slowly, revealing a little at a time.
Frog dissection is a process of examining the internal anatomy of a frog by making cuts through the skin and muscles. During the dissection, students typically examine the organs, including the heart, lungs, liver, stomach, and intestines. In fact, this is quite a sensitive process and requires some specific tools. The Virtual Frog Dissection by Steve Velie and Tim Hall is an exceptional resource, taking teachers and students step by step through a frog dissection and identifying structures both internally and externally.. Teachers may find the labeled diagrams of selected body systems useful. Standards Grade 7 Structure and Function in Living Systems.
