The Prerequisite Problem in the A&P Course | Episode 61

Host Kevin Patton discusses issues caused by our expectations of anatomy & physiology course prerequisites and answers the question: which prerequisites work best? Recent reports of a bone-marrow recipient with donor DNA in his semen prompts a brief review of what happened. Wi-Fi fields can produce biological effects. What are they and how does Wi-Fi produce them?

Bone Marrow Genome in Transplant Recipients

7 minutes

Recently, the case of a bone marrow transplant recipient made the rounds. Reports mentioned that his semen contained only DNA from his donor, with none of his own DNA, which sounds weird—and perhaps not really possible. We explore what really happened—and how we might use this story to teach A&P.

Watch Out for Wi-Fi

7 minutes

Wi-Fi forms an EMF (electromagnetic field) that can produce unwanted biological effects in humans. In this segment, we explore them, as well as the proposed mechanism. That mechanisms is based on a core concept of physiology that we can leverage for showing students how "all that detail" can help them understand contemporary health issues.
