Muscle Structure Describe the hierarchy of organization in muscle Distinguish smooth, skeletal and cardiac muscle based on histology Understand and rationalize the differences between fiber types Know the skeletal muscle sarcomere structure cold.
Muscle Contraction Know each step in transmission across the neuromuscular junction Know each step in E-C Coupling for striated muscle Know each step in the cross-bridge cycle for striated muscle Know the differences between smooth and striated (skeletal + cardiac) muscle
Preload and Afterload Preload The force (load) a muscle exerts prior to contraction. Pre-contraction Afterload Force muscle exerts during contraction. After [the start of] contraction Demonstration
