Exploring the Muscle System
Learning Objective
I can identify the major muscles in the human body and their functions.
Key Concepts
The muscular system is composed of three main muscle types: skeletal, cardiac, and smooth.
Fast-twitch muscle fibers react quickly but tire easily, while slow-twitch fibers are endurance cells that work for longer periods.
The autonomic nervous system controls cardiac and smooth muscles, while the somatic nervous system controls skeletal muscles.
