Definitions:

G-Actin

G-Actin (Globular Actin) is a monomeric form of actin that polymerizes to form F-actin filaments, crucial for muscle contraction and cell mobility.

Cross-Bridges

Molecular links between actin and myosin filaments in muscle fibers that are responsible for muscle contraction.

Incomplete Tetanus

A condition where muscle fibers produce almost peak tension during rapid cycles of contraction and relaxation.

Complete Tetanus

A condition of sustained muscle contraction resulting from rapid, repetitive stimulation that does not allow for relaxation between stimuli.
