1. The rapid and transient redistribution of Ca2+ from intracellular membrane-bound compartments (stores) is a key event of cell activation. 2. The cytological nature and molecular composition of such Ca2+ stores have been the object of intense investigation in recent years. 3. Here we review: (a) the current knowledge on intracellular Ca2+ stores of Purkinje neurons at the functional, biochemical, molecular, morphological and ultrastructural level; and discuss: (b) the relationship between Ca2+ stores and the endoplasmic reticulum, and (c) the occurrence of multiple/heterogeneous Ca2+ stores.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D004721	Endoplasmic Reticulum	A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
