Rye Neck High School students who are enrolled in science teacher Matt DeBellis’ Anatomy class have been learning about the skeletal system and different tissue types. During a recent lab activity, they were tasked with dissecting a chicken wing to further deepen their knowledge.
“The bones and overall structure of the chicken wing are homologous with the human arm, meaning the bone structure and muscle function of the wing is markedly similar to human anatomy,” DeBellis said. “By dissecting the chicken wing, the students uncovered and identified connective tissues, such as ligaments, tendons, cartilage and fat along with muscle tissue.”
During the lab, the students removed the skin with dissecting scissors and identified each muscle and bone. They recorded observations about the appearance, texture and integrity of the different structures and tissues. They also compared and contrasted the structure of the wing to a human arm and pulled on different muscles to observe the extensor and flexor articulation effect on the overall movement of the arm.
“Some of them even cut the bone in half using a bone saw, which was gifted from an orthopedic surgeon, to gain access to the bone marrow in the cavity of the long bones, which they extracted using a dissecting needle,” DeBellis said.
DeBellis said he hoped his students gained a visceral experience of what real tissue looks and feels like.
“I hope they gained insight into how the tissues and systems that we have been learning about come together in a complex yet graceful way to achieve a simple function,” he said.
