Did you know that neural signals can travel as fast as 154-270 miles per hour? In anatomy class students uncover the answers to many questions they may have about the human body To better learn about the brain, dissected sheep brains.

Ms. Jessica Baker’s third period anatomy class dissected a sheep’s brain as part of their Nervous System unit. “We spend a whole unit learning about the nervous system, so dissecting the brain gives students a perspective on where the parts are located and how they function,” said Baker. 

Ms. Baker handed out supplies to students.

Students were given a tray that included the brain, utensils, and gloves to make sure they stayed protected.

Before they could dissect, students had to show either Baker or SSL Conner Jackson that they could locate the four lobes of the brain, the brain stem, the cerebellum, and the meninges.

“Students learned the tools and the directional terms in the introductory unit of the class. They practiced using the dissection tools during our anatomy of a potato lab and have had to practice using the terms throughout the semester. Students were provided a guidebook to walk them through the dissection. My SSL and I split the class in half in order to help with the discussion and answer questions more efficiently,” said Baker. 

Groups of two or three worked on guide that included step by step instructions on how to dissect the brain. “It was very easy to follow. We had a packet that guided us, and included articles we had to read with questions as we went through the dissection,” said senior Brynne McKinney. 

The students were consumed with curiosity as they read through their packet and began cutting. As students went through their dissection, they were able to see a very similar replica of what the human brain looks like, only smaller.

“I think the dissection was a useful experience. It was nice to get to identify the different parts of the brain with an actual brain in front of us, it makes it easier to picture the different parts of the brain,” said McKinney. 

Each group had a sheep brain and the tools for dissection.

The brain was just the first organ of many that they would have to dissect. There are four total organs used for dissection ,and they all come from sheep. Students will have to dissect the brain, the eyes, the heart, and the kidneys. Once they arrive to the dissection of the heart, they will be taught how to properly suture an organ.

Students were extremely eager to dissect, but were hesitant at the sight of a brain. Even though it may have been an odd experience, it would have a positive impact on the students, especially those who wish to pursue a career regarding anatomy, and the brain (human or animal).

Baker said,” The goal is to have students identify the parts and relate them to what we covered in class. They need to practice dissections if they hope to become doctors or nurses some day.”
