This blog is devoted to BIOL 6988, a graduate level seminar in the biological sciences at Youngstown State University. While targeted towards graduate students, BIOL 6988 actively incorporates undergraduate participants in their scholastic endeavors in the biological sciences. This blog is intended as a educational tool not just for YSU students and faculty, but for anyone who wishes to contribute to an active-learning environment.
Due to the coronavirus pandemic, Angela shall send out her presentation as
a voice-over PowerPoint. This post represents the spot where grad
students in BIOL 6988 are to comment on her presentation.
Angela Mosser has been working in Dr. Butchers Lab and presented her seminar presentation titled "A horse of a different color?: Tensile strength of bones and tendons in sloth limbs". While it may appear comical comparing the musculature of a sloth and horse, there are some interesting parallels that can be drawn. For one, horses and sloths have ample suspensory ligaments in their bodies, which demands relatively low amount of energy compared to other animals which stand/hang most of their active periods. Sloth limbs specifically aren't built for compression forces because of this, compared for instance to us humans who have dense bones because we fight gravity when we stand. Sloth tensile strength and their musculoskeletal system is build more for slow, controlled brachiation through trees, which may be a hint as to why it's bones withstand less compression.
Angela plans to continue this and other research at Kent State University/NEOMed where she will be pursuing her Ph.D. Congratulations Angela.
Excellent presentation and congratulations on getting accepted to Kent State/NEOMED, Angela! I thoroughly enjoyed this presentation. I got a kick out of the upside down horse statue. I was impressed by her data and results. In particular I thought the 3 point compression tests on the bones was cool cause in the video she showed it looked as if one end of the bone experienced some internal rotation as more force was applied, but was able to return to its normal shape once the force was backed off. Also, side note the title kinda made me think of an old meme, "Who would win, a lion or the same lion but upside down" except with sloths and horses.
Angela gave a great presentation! It is very clear how passionate she is about her field of research and it shows through when she presents. I never realized how much could go into studying sloths, especially their bones. The compression strength testing was especially interesting and cool to watch a small video of! Who knew sloth bones wouldn't break under all of that pressure!
Angela presentation was very engaging especially the pictures she used in her power point.The title itself was interesting "A horse of a different color?: Tensile strength of bones and tendons in sloth limbs".The video showing the compression strength test on sloth bones showed interesting results as to how much much pressure they can withstand.
Having Angela present her talk as an actual presentation was quite a change versus the rest of our talks. She had quite a lot of background on the mechanics of her research. I don't know much about biomechanics, but there is a hope that this research will continue to grow and develop.
First, congratulations Angela for your admission at Kent State university/NEO-MED. Angela's presentation was tremendous. I loved the way she used pictures and videos to show tensile and compression strengths and musculoskeletal systems.Her area of research is truly one of its own and her passion as demonstrated when presenting gonna land her to greater heights. Good job.
Angela gave a wonderful presentation on the comparison of the musculoskeletal systems of horses and sloths. I listened to Dr. Butcher’s seminar presentation from last semester on creatine kinase’s involvement in sloth suspension, so it was interesting to compare the biomolecular aspect of suspension to the biomechanical aspect of suspension. Also, congratulations on your acceptance into the PhD program at NEOMED!
