Identify the glottis and the opening to the esophagus.Cut through the jaw joints on each side of the mouth and open the mouth wide.The cloacal opening, or anus, is the single exit from the urinary, reproductive, and digestive systems. Locate the cloaca at the specimen’s posterior end.When done, you should be able to easily open the mouth to examine these internal mouth structures. Use the scissors to cut the back of the mouth where the mandible attaches to the maxilla.

Some of these photos were used to create a a Quizlet: Frog Anatomy to help students prepare for the frog practical. Most of the photos have two versions, a labeled version and an unlabeled one which can be useful for quizzing students. Frog : 1-organs are labeled and color coded, 2-on the back of the page, organs are defined. The linked photo album shows all of the structures that are visible during a frog dissection, such as the liver, gall bladder, stomach, intestine, spleen, eggs. The optional third day allows for students to catch up or make up any of the required activities from day 1 and 2. which the students will label and give the function of the parts and organs of the frog. Frog specimens are ordered from biology supply companies, or can be ordered from Amazon: Nasco Grass Frogs and students spend about 3 days on the dissection: 1 day for the external anatomy, 1 day for the digestive, and then a third day where students can optionally remove the brain and leg bones.
