The Purkinje system includes the bundle branches and the peripheral fibers.

Purkinje System

A network of fibers in the heart that distributes electrical impulses, contributing to the coordination of heart muscle contractions.

Bundle Branches

The paths of specialized heart muscle cells that transmit electrical impulses from the heart's atrioventricular node to the ventricles, ensuring coordinated heart muscle contractions.

Peripheral Fibers

Nerves located outside the central nervous system, involved in the transmission of sensory and motor signals to and from the central body.
