INTRODUCTION

In this lab, we studied the anatomy of a frog. By doing this, we got a better understanding of the different systems and how they work, further reflecting on those of the human body. Due to personal preference, I did not participate in the dissection. As an alternative, my peers and I were able to complete our lab by research. In the lab, we studied the external anatomy, the mouth, the overall internal anatomy, the skeleton system, the muscular system, the circulatory system, the respiratory system, the digestive system, the reproductive system, the excretory system, and the nervous system of a frog as well as a few comparisons between specific parts of the human and frog body.

BACKGROUND INFORMATION

Frogs are amphibians that belong to the chordate and deuterostome phylum. Animals of the chordata phylum all have a notochord, a dorsal nerve chord, and gill slits. Meanwhile, those of the deuterostome phylum all go through deuterostomy during their embryonic development.

Reflection

The anatomy of a frog in comparison to the anatomy of a human differ in many ways. For example, the human heart has four chambers while the frog heart only has three. Also the frogs tongue is attached to the front of the mouth while ours is attached to the back. Lastly, frogs only have one bone in their lower leg (tibia-fibula bone) but humans have two (tibula bone and fibula bone). Before the lab, I had a hard time processing the fact that we would be touching the internal anatomy of a frog. Because of that, I really appreciated the fact that I was granted the privilege to complete the lab outside of the classroom as a research study vs a dissection. Although, I would've rather completed fewer essays and put more effort into them instead of many essays with minimal effort. One thing that I would like to further learn about is the nervous system.

Throughout the lab, the amount of collaboration and communication was clearly present. Together, my peers and I were efficiently able to work together to find the correct information to complete this lab. Although, I would like to become more culturally competent and be more open-minded towards participating in the actual dissection.
