Glossary Term
Sarcomere
A segment of a myofibril (muscle cell) from one Z disk to the next. This is the smallest functional unit of a muscle cell. A muscle shortens because all of the individual sarcomeres shorten, pulling Z disks closer to one another. Example: A sarcomere is the smallest functional unit of a muscle cell, discussed when teaching contractile proteins, the sliding filament theory and length/tension relationships.
