Overview
The sarcomere is the fundamental unit of muscle contraction, composed of actin and myosin filaments. These filaments interact through a process known as the sliding filament theory, where they slide past each other to shorten the muscle. Understanding the structure and function of sarcomeres is cruc...
Key Terms
Example: Actin filaments are essential for muscle contraction.
Example: Myosin interacts with actin to facilitate muscle contraction.
Example: Z-lines anchor actin filaments.
Example: The A-band contains myosin filaments.
Example: The I-band shortens during muscle contraction.
Example: According to the sliding filament theory, muscle contraction occurs when actin slides over myosin.
