The Muscular System show art The Muscular System

MCAT Basics (from MedSchoolCoach)

This MCAT BAsics episode covers the muscular system. It begins with the differences and similarities between the three types of muscle (smooth, cardiac, and skeletal). Then, the podcast explores the basic structure of a skeletal muscle cell and the various organelles unique to this cell type, including the sarcolemma, sarcoplasm, myofibrils, sarcomeres, and more. Next, it discusses three main differences between Type 1 and Type 2 muscle fibers. Finally, it delves into muscle contraction, starting at the neuromuscular junction and ending with the shortening of sarcomeres, which causes muscle...

More Episodes

In this episode, we cover motivation and emotion–key concepts that will show up in the Psychological, Social, and Biological Foundations of Behavior section of the MCAT.

We start with the difference between intrinsic and extrinsic motivation. We then go into various theories including evolutionary, arousal, drive-reduction, incentive, three needs theory, Maslow’s hierarchy, and the correlation between harmful behaviors like addiction and motivation. 

Lastly we get into emotion, covering its three components, the relationship between emotion and the brain, and an array of theories including evolutionary, James-Lange, Cannon-Bard, Schachter-Singer, Lazarus, and facial feedback theories. Additionally, we discuss the influence of culture on emotion and delves into emotional disorders.
