Human Diseases students dissect anatomical structures Sullivan's class observes bones; Smith's class observes hearts

To accompany Human Diseases unit material, students have begun dissecting anatomical structures and observing them under microscopes. Dissections began this week.

“We’re looking at what bones are composed of, starting from the outside in,” Dr. Janet Sullivan said. “On the outside, there is a fibrous coat called the periosteum. Under that, there’s compact bone, then spongy bone. The students have been excited about dissecting out actual blood vessels.”

Sullivan’s students dissected bovine bones and separated arteries for individual inspection as part of the skeletal system unit. Smith’s students observed pig hearts as part of the cardiopulmonary unit.

“We looked at cow bones and took apart certain body parts,” freshman Yousef Jalal said. “It’s pretty interesting to see them all up close.”

During the dissections, students cut bones in half and verbally identified the various layers present in the specimens. The same procedure was done during heart dissections.

“I think the most interesting thing about cutting up the heart was seeing the ventricles and how they connect to the valves,” sophomore Russel Grimares said. ” I’ve only seen the heart in pictures and it was fun to see a visual representation of it.”

Dissections will end this week. A test following the procedures will be administered to students next Friday. No announcements regarding future dissection plans have been made.

“It’s really exciting to dig around and find interesting things while dissecting,” freshman Yahida Peregrina said. “I hope we get to do this activity again in the future. I feel like it’s helped me learn a lot better.”
