Definitions:

Z Disk

Delicate, membranelike structure found at each end of a sarcomere to which actin myofilaments attach.

T Tubule

T Tubules, or transverse tubules, are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells, playing a crucial role in muscle contraction.

Sliding Filament Model

A theory describing the mechanism of muscle contraction, where actin and myosin filaments slide past each other to shorten the muscle fiber length.

Sarcomere

The basic unit of a muscle's cross-striated myofibril, responsible for the muscle's contractile properties.
