All or Nothing: A Case Study in Muscle Contraction

In this interrupted case study, students pose as an intern of a neuromuscular/skeletal specialist and discover how sarin and myasthenia gravis influence muscle function. Students are given background information about the patients and their situations, as well as results from blood tests. Students are asked incremental questions that build on each other with the end goal of students describing the process of muscle contraction, from motor neuron to sarcomere shortening, and learning what happens when parts of that process are disrupted. This activity was developed for use in a physiology course where the majority of the students were pre-medical, pre-nursing, or other allied health majors.
