Skeletal Muscle and Mitochondria Physiology


Course Description

This advanced muscle physiology course will focus predominately on the biology of mitochondria and the physiology of one cell type in which the mitochondria live, skeletal muscle. Topics and discussions will range from mitochondrial biogenesis during skeletal muscle adaptation to mitochondrial dysfunction in diseases such as aging, diabetes, and Alzheimer’s.

Additional Requirements for Graduate Students:
Graduate students will have different exams than the undergraduates in order to document their advanced ability to integrate and apply research-based information about skeletal muscle and mitochondrial physiology. Also, graduate students will be required to do the following to document their advanced skills in critical thinking, appropriately evaluating the research literature, and competency in applying this research-based information: write a research-based paper that reviews a selected mitochondrial disease and treatment topic (5 to 10 pages, with 5 to 10 references).
