The Muscular System
Manage episode 425565242 series 2770060
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 flexion.
