Winter Short: Mitochondria, Platelets, Golgi, & Green Pens TAPP 127

The A&P Professor

Nov 18 2022 • 17 mins

Episode 127 is one of our winter shorts, where I replay interesting segments from previous episodes. In this one, you'll hear about the role of platelets in immunity, how the Golgi apparatus gets its weird shape, exactly how hot mitochondria get, and why we may want to consider marking assignments and tests with a green pen, rather than a red one.

Guess what? this is one of our winter shorts! Yep, that's right, it's a shorter-than-usual episode in which I present one or two, or maybe three or four, classic, evergreen segments from previous episodes that are remastered, reconstituted, and recycled for your listening and learning pleasure. But mainly it's to give me a break for self-care over the holiday season. We'll be back to our regular programming in late January.


1.5 minute

Mitochondria run about 10 °C hotter than the other components of the cell. This number may be helpful when discussing thermoregulation, metabolism, cell biology, and more.


5 minutes

I summarize the newly described functions of motile platelets (not the sticky ones) in grabbing and bundling bacteria from a site of injury. The motile platelets then deliver the bacteria to neutrophils, which gobble up the bacteria. I offer suggestions on when (and if) one could use this information in teaching an A&P course.

The Master of Science in Human Anatomy & Physiology Instruction—the MS-HAPI—is a graduate program for A&P teachers, especially for those who already have a graduate/professional degree. A combination of science courses (enough to qualify you to teach at the college level) and courses in contemporary instructional practice, this program helps you be your best in both on-campus and remote teaching. Kevin Patton is a faculty member in this program at Northeast College of Health Sciences. Check it out!

Golgi Apparatus

5 minutes

The Golgi apparatus has a distinctive flattened shape. It turns out that it's the functioning of the cytoskeleton that is responsible for that shape.

GOLPH3 bridges phosphatidylinositol-4-phosphate and actomyosin to stretch and shape the golgi to promote budding. (research article)

Green Pens

2.5 minutes

It's a small thing, for sure, but the color pen we use for grading student work can have an impact on the tone of communication in a class.
