| Purkinje c.’s |
1. large neurons in the cerebellar cortex that have piriform cell bodies in the Purkinje layer (the stratum purkinjense cerebelli) and large branching dendrite trees going through the outer (molecular) layer towards the surface. 2. cells of the Purkinje fibers of the heart; they are large, clear, tightly packed cells with many gap junctions between them and thus conduct impulses rapidly.

| Purkinje f.’s |
modified cardiac fibers composed of Purkinje cells, occurring as an interlaced network in the subendocardial tissue and constituting the terminal ramifications of the conducting system of the heart. The term is sometimes used loosely to denote the entire system of conducting fibers. See also rami subendocardiales and systema conducens cordis.
